Once Were Hairy

Aesthetically, humans are somewhat standout from the rest of natural creation. We are multicellular organisms, instantly making us completely different to the vast majority of the species’ currently on earth today, and warm-blooded, differentiating us from every plant, fungi, invertebrate, fish, amphibian and reptile. We stand on two legs, but at the same time cannot fly, differentiating us from almost every species of bird and mammal. But this is only so much basic classification; the one trait that aesthetically differentiates from nearly all of these is our hairlessness. Brian May excepted.

Technically, there are other members of the order mammalia who go without fur; the simultaneously cute and horrifying naked mole rat is but one land-borne example, and no swimming mammal (whales, dolphins etc.) have fur. And yes, we technically do have a full layer of fur covering us, meaning that you have more hairs (in terms of number, rather than volume) than a chimpanzee- but our hairy covering is so small as to be practically not there, and the amount of insulation and protection that it provides is minimal. Across most of our body, the only natural protection we have against our enemies and the elements is our bare skin.

Exactly why this is the case is somewhat unclear, because fur is very useful stuff. It offers a surprising degree of protection against cuts and attacks, and is just as effective at keeping out the elements, be they cold, wind or rain. Length can and does vary widely depending on location and need, and many species (including some humans) have incorporated their fur as a form of bodily decoration to attract mates and intimidate rivals; the lion’s mane is the most obvious example.

Also confusing is why we have hair where we do; upon our heads and around the pubic regions. It is thought that hair on the head may be either an almost vestigial thing, left over from the days when our ancestors did have hair, although this theory doesn’t explain why it remained on our head. Better explanations include the slight degree of extra shielding it provides to our brain, our greatest evolutionary advantage, or because the obviousness of the head makes it a natural point for us to rig our hair into elaborate, ceremonial styles and headdresses, raising the social standing of those who are able to get away with such things and helping them attract a mate and further their genes. However, the pubic region is of particular interest to evolutionary biologists, in part because hair there seems counter-productive; the body keeps the testicles outside the body because they need to be kept slightly cooler than the body’s interior temperature in order to keep sperm count high and ensure fertility (an interesting side effect of which is that people who take regular hot baths tend to have a lower sperm count). Surrounding such an area with hair seems evolutionarily dumb, reducing our fertility and reducing our chances of passing our genes onto the next generation. It is however thought that hair around these regions may aid the release of sexual pheremones, helping us to attract a mate, or that it may have helped to reduce chafing during sex and that women tended to choose men with pubic hair (and vice versa) to make sex comfortable. This is an example of sexual selection, where evolution is powered by our sexual preferences rather than environmental necessity, and this itself has been suggested as a theory as to why we humans lost our hair in the first place, or at least stayed that way once we lost it; we just found it more attractive that way. This theory was proposed by Charles Darwin, which seems odd given the truly magnificent beard he wore. However, the ‘chafing’ theory regarding pubic hair is rather heavily disputed from a number of angles, among them the fact that many couples choose to shave their pubic region in order to enhance sexual satisfaction. Our preferences could, of course, have changed over time.

One of the more bizarre theories concerning human hairlessness is the ‘aquatic apes’ theory; it is well known that all swimming mammals, from river dolphins to sea lions, favour fat (or ‘blubber’) in place of fur as it is more streamlined and efficient for swimming and is better for warmth underwater. Therefore, some scientists have suggested that humans went through a period of evolution where we adopted a semi-aquatic lifestyle, fishing in shallow waters and making our homes in and around the water. They also point to the slight webbing effect between our fingers as evidence of a change that was just starting to happen before we left our waterborne lifestyle, and to humanity’s ability to swim (I am told that if a newborn baby falls into water he will not sink but will instinctively ‘swim’, an ability we lose once we become toddlers and must re-learn later, but I feel it may be inappropriate to test this theory out). However, there is no evidence for these aquatic apes, so most scientists feel we should look elsewhere.

Others have suggested that the reason may have been lice; one only needs to hear the horror stories of the First World War to know of the horrible-ness of a lice infestation, and such parasites are frequently the vectors for virulent diseases that can wipe out a population with ease. Many animals spend the majority of their time picking through their fur to remove them (in other apes this is a crucial part of social bonding), but if we have no fur then the business becomes infinitely simpler because we can actually see the lice. Once again, adherents point to sexual selection- without hair we can display our untarnished, healthy, parasite-free skin to the world and our prospective mates (along with any impressive scars we want to show off), allowing them to know they are choosing a healthy partner, and this may go some way to explaining why the ultimate expression of male bodily beauty is considered a strong, hairless chest and six-pack, symbolising both strength and health. Ironically, a loss of fur and our subsequent use of clothes developed an entire new species; the body louse lives only within the folds of our clothes, and was thought to have evolved from hair lice some 50,000 years ago (interestingly, over a million years passed between our African ancestors passing through the hairless phase and our use of clothes, during which time we diverged as a species from Neanderthals, discovered tools and lived through an Ice Age. Must have been chilly, even in Africa). It’s a nice theory, but one considered redundant by some in the face of another; homeostasis.

Apart from our brainpower, homeostasis (or the ability to regulate our body temperature) is humanity’s greatest evolutionary advantage; warm blooded mammals are naturally adept at it anyway, giving us the ability to hunt & forage in all weathers, times and climates, and in cold weather fur provides a natural advantage in this regard. However, without fur to slow the process of heat regulation (sweating, dilation of blood vessels and such all become less effective when insulated by fur) human beings are able to maintain an ambient bodily temperature almost regardless of the weather or climate. African tribesmen have been known to run through the bush for an hour straight and raise their body temperature by less than a degree, whilst our ability to regulate heat in colder climates was enough for scores of Ice Age-era human bones to be found across the then-freezing Europe. Our ability to regulate temperature surpasses even those other ‘naked’ land mammals, the elephant and rhinoceros, thanks to our prominent nose and extremities that allow us to control heat even more precisely. In short, we’re not 100% sure exactly why we humans evolved to be hairless, but it has proved a surprisingly useful trait.

Leaning Right

The political spectrum (yes, politics again) has, for over 200 years now, been the standard model for representing political views, adopted by both the media and laymen alike. It’s not hard to see why; the concept of judging every political view or party by a measure of left-ness and right-ness makes it very simple to understand and easily all-encompassing, allowing various groups to be easily compared to one another without a lot of complicated analysis and wordy explanations. The idea comes from the French revolution towards the end of the 18th century; in the revolutionary parliament, factions among political figures were incredibly divisive and the source of open conflict, so much like home & away fans at a football match they attempted to separate themselves. Those sitting to the left of the parliamentary president were the revolutionaries, the radicals, the secular and the republican, those who had driven the waves of chaotic change that characterised the revolutionary period. However, as the revolution went on, another set of views formed running counter to the revolutionary ideas of the left-sitters, and who quickly found their way into an equally tight-knit group on the right hand side of the hall; those who supported the principles of the monarchy, the prominence of the church in French society and politics, and the concepts of hierarchy and rank. It goes without saying, of course, that those populating the right-wing, as it would become known were mainly those who would benefit from these principles; the rich, the upper class (well, what little of it that hadn’t been killed off) and the high-standing.

And, according to the Big Book of Political Cliche’s, right wing=bad. Right wing means uber-capitalist, aristocratic, a semi-tyrannical overseer extorting money from the poor, innocent, repressed working classes and supportive of stealing from the poor to give to the rich. The right is where racists are to be found, old-fashioned bigots out of touch with the real world, those who think slavery was an excellent business model, and the neo-Nazis (I realise I may be pushing the envelope on what the stereotype actually is, but you get my point).

However, when one analyses the concept of right-wingedness (far more interesting than the left, which is all the same philosophy with varying degrees of mental instability), we begin to find a disparity, something that hints that our method of classification itself may be somewhat out of change and in need of a rethink. Right wing is considered to incorporate both a socio-economic position (pro-capitalist, laissez-faire and ‘get the poor working’ in very broad terms) and a social equality one (racism, sexism, discrimination etc.) akin to Nazism, and nowadays the two simply do not align themselves with the same demographic any more.

I mean, consider it purely from the ‘who votes for them’ angle. In Britain, the (nowadays fairly nominally) right-leaning Conservative party finds it power base in the country’s richer areas, such as the Home Counties, and among the rich & successful capitalists, since their quality of life can be put down to the capitalist model that Conservatism is so supportive of (and their benefits from taxation are relatively small compared to the help it provides the poorer demographics with). However, far-right parties and political groups such as the British National Party (BNP) and English Defence League (EDL) tend to seek support from right at the opposite end of the social ladder, seeking support from the young, working-class, white skinhead male sphere of existence. Both of them draw support from a predominantly white power base, but beyond that there is little connection.

This is not something solely prevalent today; the Nazi party are often held up as the epitomy of right-wing for their vehemently racist ‘far-right’ policies, but we often seem to forget that ‘Nazi’ is just a corruption of ‘Natso’, short for ‘National Socialist German Workers Party’. The party’s very title indicates that one of their key areas of support was for ‘the German Workers’, making a similar appeal as the communists of the time. Although their main support was eventually found in the middle  and lower-middle classes (the upper end of the social ladder considering Hitler a poor upstart who would never make anything of himself, demonstrating exactly how out of touch they were with the real world), the Nazi economic policy that put Germany through an astonishing economic turnaround between 1933 (when the Nazis took power) and 1939 was closely centred around the socialist ‘public works & state-controlled business’ model that Franklin D. Roosevelt had recently adopted to lead the USA out of The Great Depression. Many socialists and communists would doubtless have approved, if any of them hadn’t been locked up, beaten up or on their way to forced labour camps. In terms of socio-economic policy then, the Natso’s were clearly less ‘National’ and more ‘Socialist’.

We are, then, presented with this strange disparity between the economic-policy based ‘right’ and the racism-centric ‘far right’. The two were originally linked by the concepts of nationalism and traditionalism; from the earliest days of the political spectrum the right wing have always been very much supportive of a return ‘to the old ways’, of thinking nostalgically of the past (usually because there was less left-wingedness in it) and that the modern world is getting steadily worse in the name of ‘progress’. One feature identified in this vein is that of immigration, of foreign-born workers entering the country and ‘stealing our jobs’ (et cetera), in their view devaluing the worthiness of their own country. This has made the idea of nationalism and extreme patriotism a stereotypically right wing trait, and the associated view that ‘my country is better than yours’. This basic sense of the superiority of various races is the key rhetoric of ‘Social Darwinism’, a concept pioneered by the Nazis (among others) that suggests that Charles Darwin’s ‘Survival of the Fittest’ principle should be applied to the various races of humanity too, and that the ‘better’ races have a right of superiority over the ‘lesser’ ones (traditionally ethnic minorities in the west, such as middle eastern and black), and this too is a feature of many far-right viewpoints.

But the field has changed since those ideas were pioneered; the modern world that we live in is for one thing a lot easier to traverse than before, meaning that those rich enough to afford it can easily see the whole globe in all its glorious diversity and wonder for themselves, and our increasingly diverse western society has seen a significant number of ‘minorities’ enter the top echelons of society. It is also true that using cheap, hard working labour from immigrants rather than from workers with trade unions makes good economic (if often not moral) sense for large corporations, meaning that the ‘rich capitalist’ demographic who are so supportive of conservative economic policy are no longer the kind of people who worry about those ‘stealing our jobs’. This viewpoint has turned to the opposite end of the social spectrum, the kind of people who can genuinely see their jobs being done by ‘foreigners’ and get jealous and resentful about it; it is these people who form the support bas for right-wing populists and think the EDL know what they’re talking about, and in many ways that is more worrying. The rich having dangerous, extreme views is a serious danger, but there are comparatively few of them and democracy entails just one vote each. The number of young, angry, working class white men is far larger, and it is this demographic that won the BNP a seat in the House of Commons at the last election. Will this view get more or less prevalent as time goes on? I would like to think the latter, but maybe we’ll just have to wait and see…
