Love is in the air!

Spring is coming and soon love will be in the air!  Whether it’s the pheromones of animals or the pollen of plants, the air around us is positively brimming with the scent of reproduction.

Winged creatures like butterflies often engage in courtship flights, dancing around each other as part of a pre-copulation ritual.  The courtship ritual of the bald eagle involves locking talons and tumbling toward earth…  And then there are insects which engage in aerobatic sex, mid air, such as flies and dragonflies.

When it comes to humans (and other animals) we all have a unique smell, a chemical signature that we refer to as pheromones.  They play a role in who we are attracted to which I think is fairly well known, but also, probably lesser known, is that they also help us to identify people we are related to – useful if you want to avoid sleeping with your secret cousin that no one knew about… Having different genetic make up means healthier children and less inbreeding which is why we’ve evolved to detect this.  Couples which are more genetically similar have fewer orgasms which sounds pretty rubbish but things go one step further and couples who are more genetically alike also have a higher rate of cheating…  Basically, evolution is doing everything it can to reduce the chance of inbreeding.

Pheromones are also used to help a guy to detect where in her menstrual cycle a woman is and his body releases testosterone according to ovulation status.

However, the use of hormonal contraception appears to be changing how humans react to these chemical signatures.  When taking birth control pills, the natural ability to distinguish between males who are genetically alike and genetically different is disrupted and instead, women are attracted to the males who are most similar.  Verdolin gives a great example:

“I was discussing this with my friend Stacey, who exclaimed, “That must be why I couldn’t stand the smell of my ex-husband!”  She went on to explain that when she met her first husband she had been taking birth control pills.  Several years into their marriage, after she discontinued the pill, not only was she unable to get pregnant, but she no longer cared for the smell of her husband.”

Aside: pheromones are found in underarm hair and public hair so maybe go au naturale if you’re seeking a partner?

Animals use pheromones to communicate with each other, to mark their territory and to induce aggression.  They are also used in parental bonding, to keep group behaviour in check and of course to attract mates – some creatures can even smell out virgins.  They are also used to mark your mate in order to keep away other potential mates.  Squirrels secrete pheromones onto their partners onto their partner to tell other males that she’s taken.  Queen bees use pheromones to control hive behaviour and stop workers from reproducing.  Plants use pheromones to attract pollinators, for example a kind of orchid can mimic bee pheromones to pollinate them.

Male lemmings can not only sniff out a female who’s ready to mate, but they can also distinguish between those who have mated already and those who have not.

“From beetles to bees and lizards, females do give off a different scent if they have already mated or if they are ready to mate.”
– Verdolin

A large number of male creatures will include anti-aphrodisiac pheromones in their bodily secretions so that the female they are mating will have less interest in sex.  The pheromones can also make her less attractive to other males.

What of other ways that love is in the air?  Well, plants can reproduce in a couple of ways, both involving the air; insect pollination and wind pollination.  The latter means that large amounts of pollen are released to the breeze in the hope that they find another plant to fertilise.  Whilst this does mean hayfever for many of us, it’s nice to think that it’s all in the aid of making baby trees and flowers!

“Mum, who do you love best?” – Parental favouritism in the animal kingdom

Whilst this is a question we tend to think of as being asked by a child with siblings, it turns out, animal parents have favourites too…

For example, there’s a species of budgie that regurgitates food for its young and males will feed in response to chicks begging whereas females will seek out the smallest offspring and prioritise them.  In bearded vultures, it really does pay to be the favourite; it’s common for parents to only feed the first born chick…  But it’s not just size and birth order that parents prioritise.  Sticking with the bird world, let’s have a look at a few more examples.

Eastern bluebird dads favour their sons, protecting them from danger whilst exposing their daughters.  But sons aren’t equal either, the baby which is brightest in colour will garner dads protection more so than his duller brother.  Mums on the other hand didn’t discriminate.  If we turn to coots, we find much the same, with parents preferentially feeding nestlings which have ornamental plumes over their duller nestmates.  But it isn’t always about how attractive the offspring are:

“In birds, female blue tits, for instance, are better parents to the offspring they had with sexy males.  Not only that, but if the male they have mated with has his colouring dulled, the equivalent of being made less attractive, the female will actively reduce her efforts to feed their offspring.”
– Verdolin

So, what’s going on with parents?  Why do they play favourites with their children?

Well, what resources are available is an essential part of understanding this.  If you have five chicks and food is scarce, you could split it all equally and end up with five slightly less healthy chicks, or you could allocate them in an unequal way and thus play favourites with your children.

With chinstrap penguins who have more than one chick, they will make their kids chase them for food.  The chick that wins the race gets the food and the one that lags behind will ultimately die.  It sounds incredibly harsh but if you only have enough food for one chick, you need to make sure it goes to the one who has the highest chance of surviving to adulthood and having their own chicks.  This explains why parents tend to favour the fastest and strongest of their young, but what about those eastern bluebird dads and the female blue tits?

This type of favouritism, based on appearances, is again about trying to ensure that your lineage will continue.  With the blue tits, sexy males mean sexy children who in turn will have more sex and hence more chicks themselves.  By putting more resources into caring for the chicks from the sexy male, the mummy blue tit is worker harder to ensure her young will become healthy, sexy and successful breeders themselves.  For bluebirds, the females prefer to mate with brighter males and thus in the example above, where dad is trying to protect his brightest son, he is attempting to protect the son who has the best chance of mating when he grows up.

You might be wondering though, why are daddy bluebirds so concerned with their sons and not their daughters.  It’s not just that bluebirds want to have daddy son time, it happens in other species as well.  For example, wandering albatrosses feed their sons more than their daughters and I’m sure there are many more examples out there of dads putting their effort into ensuring their sons grow up to be big, strong, sexy adults.  Essentially it comes down to wanting to continue the family line and sexy males (in species where an individual male has more sex than an individual female) will achieve that.

But it’s not even just after birth that parents play favourites, in some species there can be a disproportionate ratio of males and females born, taking the idea of parental preference to an extreme.  One example of this is the red deer which has more sons if mum is in good condition and more daughters is she is afflicted by parasites, ill health, in a lower rank etc.  This means that more dominant females have more sons than their non dominant counterparts, something that we see with macaques as well.

The Trivers-Willard hypothesis suggests an explanation for this favouritism.  The hypothesis is that with conditions are great, females should give birth to and invest in raising sons over daughters.  When conditions are poorer, the reverse should occur.  As with the other types of favouritism we’ve looked at, this is about ensuring that your children have lots of children and your line continues.  To understand why the Trivers-Willard hypothesis might hold, we need to note a few things:

  • If a mother is in great condition, she is more likely to have a child who is in great condition.
  • If a child is in great condition, they have a better chance of surviving to adulthood.
  • If the species is such that males have the potential to produce more offspring than females, then being sexy is important. If you aren’t a sexy male, then you might not attract any females, thus you won’t have any children and essentially the resources that your mother chose to give you are wasted.  Basically, mum would have been better having a daughter.

Essentially, a male in great condition will have significantly more offspring than a female in the same condition and thus is a better investment.  A male in poorer condition will potentially have less offspring than a female in the same condition and so is a bad choice to invest in.

Whilst it may not be of comfort to you if you aren’t the favourite child, at least you know you’re not alone… And just in case you were wondering, its thought that two thirds to three quarters of human parents favour one child over another…

A recipe for life

“Hence without parents by spontaneous birth
Rise the first specks of animated earth”
– E. Darwin, 1803

Spontaneous generation is the idea that life can arise from non living material at any given moment and one of the earliest references I found to the concept was from Anaximander in the 3rd century BC.  Not long after, Aristotle was writing in the 4th century about eels.  They troubled him as he could find no trace of their sex.  He concluded that eels “proceeds neither from pair, nor from an egg” but that instead they were born of the “earth’s guts”, that is spontaneously emerging from mud.  Aristotle believed that worm casts were actually embryonic eels boiling out of the ground.  Pliny the Elder had another idea, that eels would rub themselves against rocks and the scrapings would come to life.  Other eel theories included young emerging from the gills of fish, from dew or being created by electrical disturbances.  The reason that eels caused natural history such issues is because of their lifecycle which starts out at sea, away from the eyes of man.

Aristotle also thought that spontaneous generation applied to a few other creatures, often small, including flies and frogs, which were considered to be lower life forms.  Some were thought to be produced in putrefying mud and dung, in wood, in excrement, and dew.  Later, naturalists would claim that insects spontaneously generated out of old wax, vinegar, damp dust and books.  Even decaying larger animals were thought to generate these smaller lifeforms.  Horses were thought to be transmogrified into hornets, crocodiles into scorpions, mules into locusts and bulls into bees.  Rats were said to come from garbage, aphids from bamboo, flies from sweat and ants from sour wine.

Athanasius Kircher included ‘recipes’ for life in his 1665 book, for example, to create frogs, you needed to collect clay from a ditch where frogs have lived, incubate it in a large vessel, add rainwater and voila!

Jan Baptist van Helmont in the 17th century tells us how to make poisonous, predatory arachnids; fill a hole in a brick with basil, cover with a second brick and leave in the sun.  To make mice, he instructs us to place wheat and water in a flask, cover with the skirt of an unclean woman, leave for 21 days and there you’ll have baby mice.  Another mouse suggestion was that they emerged from the earth and in some places you could see them fully formed as far as the breast and front feet, the rest still just mud.

To make flies, you collect fly cadaver’s, crush them slightly, put them on a brass plate and sprinkle with honey water.  You can make bees by killing a bull, putting the corpse on branches and herbs during spring and by summer you’d have your bees.  Oysters would grow from slime, cockles from sand and salamanders from fire.

Whilst all of this sounds absurd to us today, if you put yourself in their shoes, I think you’d struggle to find a better theory.  After all, caterpillars don’t have parents that resemble them, and when they die (turn into a chrysalis), they create a butterfly.  Mushrooms grow from dead logs, mould appears out of nowhere and then there are the ‘annual’ fishes of Africa and South America:

“Their lifestyle is almost magical.  They live in puddles, ponds and ditches that dry up for part of the year.  When the puddles dry up, they die.  Only their eggs survive, buried under the dried mud, waiting for the next rains.  Collect mud, add water – and presto, you get fish.  You can see why people believed in spontaneous generation.”
– Olivia Judson

Over time, the idea of spontaneous generation began to be questioned.  In 1646 a sceptic was ridiculed for questioning the idea but Francesco Redi would seek to disprove the idea that maggots grew out of raw meat with experiments in the 17th century (he still believed that living matter could create other living matter eg trees creating wasps and gallflies).  Unfortunately, his results were questioned, holes were poking in the methods and John Needham would go onto ‘prove’ via another experiment that spontaneous generation was of course real.  Needham’s experiment took gravy and heated it, then sealed the end of the flask and the idea was that nothing could survive the heat or get it as it was sealed.  When life started to form, Needham was validated in his belief.  However, he hadn’t heated the flask high enough to kill the bacteria enclosed in it so they survived the process.

Other people would work at disproving spontaneous generation including Lazzaro Spallanzani who built on the work of Redi, but it wasn’t until Louis Pasteur came onto the scene in the 19th century that the theory was conclusively disproved.

Ultimately, by investigating the theory of spontaneous generation, we would come across pasteurisation and the field of microbiology would be born.

The holly and the ivy (part two)

So, I sat down to write a post about holly and ivy… And then realised I did that last year… In my defence, I was very ill and very starved so my memories of that period are a bit vague…

That being said, I have got new books and new sources and so on since so I thought I would revisit this seasonal topic anyway, possibly focusing more on the mistletoe instead.

Holly

Holly is a plant of lightening, eternal life and the White Goddess (before it was co-opted by Christianity).  The berries, being scarlet, could be used to repel witches and Pliny the Elder went a step further and said that holly trees around the house prevent sorcery.  Self seeded holly plants would bring good luck as well as protection from storms and fires.

There are two kinds of holly, the male prickly version and the female smoother type, and according to a Derbyshire tradition, they should be brought into the home at the same time.  This would ensure that the year ahead would be prosperous.  If you accidentally brought the male holly in first, the master of the house would have absolute rule in the year ahead and if you brought the female holly in first then the mistress would be in charge.  Despite this, there is also a tradition that says that holly shouldn’t be brought indoors at all.

Whether you decorate your house with holly or not, you shouldn’t harm a holly tree.  One explanation is that holly was the tree on which Jesus was crucified and so hurting the tree would lead to his blood and tears flowing out of the wound.  Another is that holly sprang from Christ’s footsteps.  Holly is also said to be representative of his crown of thorns, the red berries his blood and the white flowers a reminder of purity and his virgin birth.

Ivy

Like holly, ivy has a mixed reputation.  During the 19th and 20th century, some people considered it unlucky and wouldn’t bring it into the house at any point in the year, possibly because ivy is associated with graveyards.

“Anyone who wishes to dream of the devil; should pin four ivy-leaves to the corners of his pillow”
– Cornish Folklore, The Penguin Guide to Superstitions of Britain and Ireland

Other uses for ivy in divination include popping a leaf in your pocket before you leave the home and the first male you see will be your future husband.  Ivy can also be used to foretell death.

Ivy leaves have been recommended as a cure for various ills including corns which could be treated by wrapping the leaf around the corn.  Cups made out of ivy wood were thought to cure whooping cough.

Ivy was said to be sacred to Dionysus and Bacchus, gods of wine, and thus was hung outside inns to show that good wine could be found there.

“In ancient Greece it was called cissos because, according to a mythological legend it was named after the nymph Cissos, who, at a feast of the gods, danced with such joy and abandon before Dionysus that she fell dead from exhaustion at his feet.  Dionysus was so moved by her performance and untimely death, that he turned her body into ivy, a plant which graciously and joyfully entwines and embraces everything near it.”
– Folklore and Symbolism of flowers, Plants and Trees

Ivy growing on a home would protect the inhabitants from witchcraft although if it starts to wither, watch out for disaster, infertility, infidelity or financial problems.

Ivy has become associated with love and fertility, possibly as it clings to all it touches…

Mistletoe

And talking of love… I don’t mean to put you off kissing under the mistletoe but…

The toe of mistletoe meant twig and mistel may be connected to the Germanic word for dung… Possibly because a common belief was that mistletoe didn’t grow from seeds but instead was the result of bird droppings, because it only grows high in trees and never on the ground.

In Scandinavia, we have stories of the gods and the much loved Balder began to have nightmares.  In order to try and ease his fears, his mum, Frigg, stepped in:

“Goddess Frigg made all swear never to harm Balder the god of light, but she overlooked the insignificant mistletoe plant, deeming it too young to swear the oath.  Loki, spirit of evil, gave a mistletoe dart to Hod, the blind god, who, unseeing, threw it and killed Balder.”
– Discovering the Folklore of Plants

The idea of kissing under mistletoe in Britain at Christmas was first reported in 1813 and may well be the result of misunderstanding that dates back to Pliny the Elder in AD77…  With this in mind I’m not going to look at the idea that it has links with paganism and druidy, this is covered in detail elsewhere and may be part of convoluted information initiated by Pliny…  That said, one article I read (I accidentally deleted the link) suggested the shape of mistletoe was reflective of a certain piece of anatomy and thus might be the reason for the link with sexuality and love…

In terms of superstitions and traditions, there are limited associations beyond kissing, however:

“It is considered very unlucky for a house unless some mistletoe is brought in at Christmas.”
– Derbyshire tradition recorded 1871

“If you want to have extra good luck to your dairy, give your bunch of mistletoe to the first cow that calves after New Year’s Day.”
– Yorkshire tradition recorded 1866

“If you hang up mistletoe at Christmas, your house will never be struck by lightening.”
– Staffordshire tradition recorded 1891

In Herefordshire, mistletoe was thought to be associated with dark magic and wouldn’t have been taken into the home lightly or used to encourage kissing.  So think carefully the next time you find yourself under a sprig with someone else…

Let’s do it like they do on the Discovery Channel…

Whilst my last post focused on sex primarily in a reproductive context, animals have sex for many reasons, just like humans do.  However, “for decades, biologists, anthropologists and psychologists have suppressed inconvenient evidence of homosexual behaviour among the human and nonhuman animals they observed” (Julien Dugnoille).

I’m going to start by looking at same sex activity as it’s one clear thread of evidence that not all animal sex is for reproduction.

There are many more bisexual animals than we tend to think and note I’m saying bisexual because often the animals aren’t solely engaging in same sex activity (which I’m going to say because same sex sex is a mouthful!).  Often, they are also having sex with the opposite sex when the opportunities arise.  The BBC also discusses whether we can claim some animals are homosexual as opposed to bisexual.

Ultimately, these are human enforced labels and as Eric Anderson says:

“Animals don’t do sexual identity.  They just do sex.”

You’ve quite possibly heard about the ‘gay’ penguins in a zoo.  They coupled up and started building their nest and sitting on rocks.  When the zoo realised what was going on, they placed an egg from a female penguin who was struggling to care for it in the nest.  The male penguins successfully incubated and raised the chick.

Same sex dolphins can become partners for life engaging in sexual behaviour, for example males can have a temporary female relationship but will return to the initial male partner afterwards.  Further, two male couples can join up to become a foursome.  One theory is that it helps to have a companion when feeding and resting because they can look out for danger.

Some male greylag geese pair up and when it’s time to raise children, they find a female and raise them together as a trio.  Some don’t but research shows the advantage of a trio; there is better defence against predators, the female has a higher social rank and better chance of survival and the female has more time to devote to her chicks because two males are helping.  After the chicks are raised, the males stay together whilst the female leaves.

In a reverse make up, roughly 2% of oystercatcher breeding groups are made up of two females and one male.  Additionally, up to a quarter of black swan families include parents of the same sex (Scientific American) and in some bird species, males steal eggs from females and raise them in same-sex unions.

Whilst these examples might feel like the exception to the rule, observers have witnessed as many as 1500 species of wild and captive animals engaging in same sex activity.

“Homosexual behaviours is surprisingly common in their animal kingdom.  It may be adaptive- helping animals to get along, maintain fecundity and protect their young.”
– Emily Driscoll, ScientificAmerican.com

Moving on from same sex activity to other non reproductive sexual activity, we find types of fruit bats who engage in oral sex, both female on male and male on female.  There is also masturbation and attempts to mate with the dead…

But what is all this sexual activity about?  Obviously, some sex is about reproduction, but pleasure, bonding and keeping the peace are all reasons for engaging in sex.

Bonding can be important for group species and strong bonds can be very helpful when facing off rivals or seeking protection from other group members.  This bond is also important in maintaining a strong group dynamic and sexual activities can diffuse social tensions.  Another type of bond is that of a parenting couple who may engage in sexual activity to maintain their bond whilst raising their young.

It’s interesting to look at an example, the bonobo.  Bonobos use sex to greet each other, to resolve conflict and for pleasure.  They engage in mutual masturbation, oral sex and penis fencing and are in general a very peaceful species.  Perhaps humans would be more chilled out if we had more sex?

But lets take a second to focus back on masturbation.  As well as humans, many other primates engage in masturbation and this can range from simple stimulation with their hands through to using twigs and leaves and other inanimate objects.  Females have been observed inserting objects into their vaginas and one male orangutan created his own sex toy:

“In one display of sexual ingenuity, a male orangutan created his own ‘sex toy’ using a large leaf, through which he poked a hole with his finger.  He then proceeded to thrust his erect penis through the hole for additional stimulation.”
– Carin Bondar

Sexual activity may also help some animals to reiterate their social hierarchy and may allow individuals to climb the ranks.

In some cases, animals may engage in non reproductive sexual activities such as same sex sex in order to gain sexual experience.  It’s interesting to note that it seems that same sex activity appears to be more common in captivity (although that could just be because its easier to observe), possibly because of a lack of alternative options and greater need for stress release.  In a similar way, you tend to find higher than ‘natural’ rates of same sex activity in prisons.

Time for another example!  Most penguins are not monogamous but it is by turning to Adelie penguins that we really get our eyes opened.  A scientific paper from 1915 had been hidden away for years, labelled not for publication and when it was rediscovered in 2009, it became clear why scientists of the time were reluctant to publicise the observations.

“They were ‘gangs of hooligan cocks’ whose ‘passions seem to have passed beyond their control’ and whose ‘constant acts of depravity’ run the gamut of masturbation, recreational sex and homosexual behaviour to gang rape, necrophilia and paedophilia.  Chicks were ‘sexually misused by these hooligans’, including one who ‘misused it before the very eyes of its parent’.  Strayed chicks were crushed and ‘very often suffer indignity and death at the hands of these hooligan cocks’.”
– Lucy Cooke quoting Dr George Murray Levick

Whilst this all sounds incredibly shocking, there is an explanation.  Adelies get together in October, flooded with hormones and only a few weeks to mate.  Young males are inexperienced and don’t really know what to do or how to act and this can lead to some questionable activity…  In their hormonal eyes, a frozen penguin in the right position can look a lot like an interested female… Apparently necrophilia isn’t just restricted to penguins…  Lucy Cooke references pigeons mounting dead house martins, male house sparrows attempting to mate with dead females and the same going on with a couple of pheasants…

In addition to all of this wonderfully interesting and fun goings on, we have those animals which change sex.

Birds do it, bees do it, even educated fleas do it…

Sex in the animal kingdom is vastly more exciting than much of human sex.  Just look at the praying mantis – she literally eats her mate!

The sex lives of animals are just as diverse as the different species are and, despite what some people might have you think, sex in the animal kingdom isn’t just for reproduction.  We can be sure of this because some animals have sex when they aren’t in season and so reproduction is not an option, and others engage in masturbation and same sex sexual activity.  That being said, in this post, I’m going to look at the sex itself and consider other sexual activity in another post.  To start with, let’s take a quick look at how you might attract a mate.

If you’re a male hippo, you might try spraying urine and faeces over the female that’s caught your eye.  A male bowerbird will build an elaborate bower to entice a female.  Other creatures might identify an appropriate male through song or scent or via chemical signals in urine markers.  For sea slugs, it’s a poke between the eyes that gets your partner in the mood…  Violence is also a hallmark for elephant seals, with the male being much bigger than the females.  A male will fight for a beach and then mate with all the females on it.  Whether they want to or not.  Some creatures will even use electricity to try and attract a suitable mate.

In different species, what makes an attractive mate differs.  For female zebra finches, it’s the level of exploratory behaviour that matters whereas for orangutans, it’s all about the males ability to share.  In the orangutan world, a male who shares is important because males can be coercive and sexually violent towards females.

If none of this convinces you of the complex nature of animal sex, perhaps you should check out the leopard slugs mating process, of which there is a handy youtube video.

Lets also take a quick look at pandas; pandas are well known for being terrible at sex but this isn’t the case.  A big issue with breeding in captivity has been trying to pair up same sex pandas and expecting baby pandas…

“The wild panda is a secret stud, fond of threesomes and rough sex… Female pandas prefer the males that can leave their sexy scent marks the highest up a tree.  Scientists have described males adopting a selection of athletic poses – ‘squat’, ‘leg-cock’ and, most remarkably, ‘handstand’ – in order to squirt their pee as high as possible.”
– Lucy Cook

We often assume in the animal kingdom that if monogamy is not the norm for a species, that it’s the male who has multiple partners whilst females have one.  This is not the case.  And biologically it makes sense.  If a female mates with a male and then realises there’s a better male, she’s going to want her babies to come from the second male so they are of the best genetic quality.  Additionally, there is a lot of sexual violence and coercion so the female may have been forced into mating with a male she doesn’t want to reproduce with.  For some males, a gift can entice the female and, in those species, it makes a lot of sense for the female to play the field!

“Female fallow deer deliver only a single offspring per year and therefore have limited chances to get it right.  They often seek the most dominant eligible bachelors for sperm deposits: however if too many females have ‘come-a-calling’ he’s liable to be sperm-depleted or may provide ejaculates with a more limited supply.  With only one offspring per year, it’s vital for females to ensure successful fertilisation, so they often engage in polyandry as a form of insurance.”
– Carin Bondar

When it comes to sex organs, the animal world is also pretty diverse.  Opossoms have bifurcated penises and vaginas which can accommodate these.  Hyena’s clitoris very closely resembles a penis and extends to an impressive 20cm!  The female spotted hyena is the only known mammal with no external vaginal opening, instead they have to urinate, copulate and give birth through the pseudo-penis… Painful!

Looking to the males of the world, we find a beetle with a spiny penis and ducks with corkscrew penises (and females with corkscrew vaginas of course).  Slugs also have corckscrew penises and if they happen to be reluctant to come out again after sex, the partner will just, er, nibble it off…  For the tuberous bush cricket, it’s the testes that cause the problem, taking up most of their abdomen:

“At nearly 14% of their body weight, they are disproportionately large when compared to other species. Just think, a 100kg human would be walking around with 14kg of testicles, which would be mighty uncomfortable.”
Susan Lawler

But if you thought that was mind blowing, wait till you hear about the Drosophila bifurca, or to you and me, a kind of fly.  The male produces 6cm sperm, more than 20 times the length of the male!

We tend to assume that orgasms are strictly a human affair but this isn’t the case at all.  scientists have detected orgasm in many different species including macaques, orangutans, gorillas and chimpanzees, although it should be noted these are generally the males of the species.  Perhaps because most human research about orgasms is about men and so the markers of an orgasm are male centric…  But that’s just this feminist’s ponderings about why…

There are also those animals that never have penis in vagina sex.  For example, African mouthbrooder cichlids reproduce orally.  Males will approach a female who then opens her mouth, which is where she carries her eggs, the male then sprays the eggs with sperm and fertilises them. Females will carry the eggs in her mouth until they hatch…

The argonaut octopus also doesn’t need to have ‘traditional’ sex.  Despite being very sexual, they engage in something called tele-sex where sperm is produced in a specially adapted penis which then detaches from the body and swims off to find a female. This penis then impregnants her and eventually the male regrows a new penis.

In another post I will consider animal sexuality but as a taster of what is to come, consider the whiptail lizards – a species made up entirely of females.  Instead of mating in the conventional way, or as a result of having both sets of organs, they make clones of themselves!  That said, they still need to engage in a mating ritual to stimulate egg production…  As only females are available, they take it in turns to act of the roles of males and females.

All of these weird and wonderful sounding sex lives just scratch the surface of how animals reproduce.  And as sex isn’t confined to reproduction, in another blog post, I’ll be looking more into the types of activity animals engage in without expecting babies to come along.

The Mother of the Mountains

If a mama bear gets angry, imagine the Mother of the Mountains.
Mess with Her children, She’ll dust off an avalanche;
step out of line, She’ll realign your bones.
She’s a blue-eyed beauty,
and the mountains have their Mother’s eyes: deep lakes.
Gaze into them, you’ll see their thoughts like fish –
quick schools, slow rainbows – look deeper,
and you’ll learn to dream like a stone.
What does She feed them? Rain for breakfast.
Anything else? She peels them the sun for lunch.
And at night? Big helpings of quiet,
then the Mother of the Mountains sings them to sleep with snow.
The trees are Her grandkids; She brings them birds to play with.
Whenever it’s their birthday, She gives them an owl
’cause though She’s a blue-eyed beauty, She’s still kind.
Even soft  . . . even fragile . . .
Wolves howl to Her to show their gratitude. What about you?

Rob Carney

I love this way of looking at the mountain, a true deep personification, the mountain as mother, as provider and as oh so loving.

If a mama bear gets angry, imagine the Mother of the Stars.
Mess with Her children, she’ll scatter white hot embers
and comets that burn
slowly
making Icarus seem like the lucky one.

Step out of line, She’ll set Draco on your trail.

She’s a wild eyed goddess
and the stars have their Mothers smile: radiating luminosity, intensity
burning bright.
Daring you to look and
punishing if you try.

What does she feed them? Diamonds and moon dust,
meteorites and wonderment.
She picks planets as though they were grapes,
offering them out as treats.

And at night? She drapes the sky with lush black velvet
then the Mother of the Stars steps back into the wings and lets her lovelies shine.

The milky way hides her grandkids as they grow;
She brings them tales from the cosmos, millennia old,
to fuel their fires and light the sparkles in their eyes.
Whenever it’s their birthday, she gives them pencils of sunlight
to practice joining dots into constellations.

Down on earth, eyes heavenwards, owls gaze in awe and gratitude.
What about you?
