Gender Evolution: Division of Tasks and Groups

Gender is innate.  It is not a social construct This article discusses how it evolved.

Early human society was fluid, with survival always the goal. It was, in general, divided by sex. Women and children formed a home group, which focussed on protection of the children and nursing mothers, foraging, perhaps trapping small game and birds, and the preparation and cooking of food. This group would have been a sisterhood of equals, but led, in all probability, by the elder women, the grandmothers, who were also the teachers, the midwives and shamans.

The other group was of men and older boys, based on the hunt. This group had to be able to respond quickly to the changing circumstances of the hunt, which could, especially when hunting large game, be lethal. A command system developed, probably around the best and most experienced hunters. We call this the ‘away’ group.

These two groups have long been identified and are still obvious in non-Western societies today. They are the evolutionary basis of gender.

Men and Not men

Professor Don Kulick, in his 1998 book ‘Travesti’ describes these groups as ‘men’ and ‘not-men’. Others use different terminology; we will use ‘home’ and ‘away’ to avoid any gender confusion.

The home group is built around the grandmothers, who are the matriarchs. with them are the younger mothers and their children. Here too, are the great-grandmothers and even older generations. These form a ‘council of the wise’, but the day-to-day management is handled by the grandmothers. In this group, too, we find Gender Non-Conforming males. These, in traditional culture, often adopt the dress and behavioural characteristics of the women surrounding them. Principal within this group are homosexual men. Also a part of this group, but somewhat at arm’s length, are the grandfathers and older generations of men who can no longer hunt, or, in modern societies, go out to work. They tend to socialise together, but they stay close tot he orbit of the home group.

The away group consists of the remaining men and older adolescent boys who are physically fit and able to hunt, or, again today, go to work. This group’s membership is strictly policed in terms of behaviour. Those in it, when not hunting or working, the modern equivalent for most, will smoke, drink, talk about sex, encourage each other to pursue women, relate their triumphs and so on. In today’s cultures they may play sport, and if they do, it will be a contact sport like soccer or basketball.

Sexual behaviour is extremely important within this group; although, in many cultures, the men will have sexual relations with adolescent boys, they must not allow themselves to be penetrated, or they will lose status. They may be shunned, ejected from the group, beaten or even killed.

If a man is ejected, then his life becomes very difficult. He will not be accepted within the home group, which will reinforce the away group’s opprobrium. He will likely become an outcast, a lost soul with allegiance to neither his away group nor his home group, Reduced to desperation and starving, he may become a sort of bandit, joining with men rejected from other groups to form new bands — which may prey on the ones they were forced out of.

Men’s susceptibility to peer pressure and their deep sensitivity about homosexual activities may well have its root here, in the dire social consequences of transgressing the away group’s rules.

The Evolution of Gender

These two social models, the home and away groups, give us the

archetypes of the two earliest deities we know of: the Mother Goddess and the God of the Hunt. The former represents the idealisation of the women at the centre of the home group and the latter the idealisation of the hunters and the complementary ‘out’ group. This tells us that gender, the physiological, social and behavioural differences consistent with birth sex, is an essential part of being human.

This ‘two-group’ arrangement minimised the risk to fertile women and young children, and meant that hunters could move quickly and silently, an impossible thing to do with babies or toddlers. Neither group was superior. Each had its area of life, which did not interfere with the other. The hunters could provide meat, animal fat, skin and bone, and the gatherers would catch small game and collect vegetables and grains, nuts, berries, roots and fungi, as well as firewood. The division of roles by gender was the beginning of task specialisation, which always leads to improvements in performance. It is likely that without such a social structure, Homo sapiens would not have been nearly as successful as a species.

Discussing this separation of tasks by gender, Steven Kuhn, from the University of Arizona, says:
‘The competitive advantage enjoyed by modern humans came not just from new weapons and devices but from the ways in which their … lives were organized around…roles for men, women, and children,’

Task Divisions

The task divisions between groups were not quite rigid. When game was scarce or the weather too bad to hunt, the men would join in to help the women to forage, set snares for small game and catch fish in the rivers. When a herd of big game that could feed and clothe the tribe for months was spotted, everyone, men, women, and children, might have joined in to drive them towards the spears or over the edge of a cliff. In some modern hunter-gatherer cultures, women and children even follow the hunting men, as spectators.
The divisions, which we still find in extant hunter-gatherer societies, may have had a consequence that remains important. When men hunted for bigger game they would travel far from their bases, and inevitably would have come into contact with other people. Should the two tribes come together and cooperate? If they do, who will lead them? There is game nearby – should we cooperate just on this occasion, to improve the chance of success? Suppose the other group is hostile – should we stand our ground and fight for this territory, move on, or just agree on a boundary? These difficult and important decisions, which impacted the whole tribe, would necessarily have been made there and then by men. Perhaps here we see the beginning of political activity between societies, and already the separation of tasks tended to ensure that it would be the domain of men.

Adult Human Males and Females are Different

Human males and females have morphological, skeletal and physiological differences. Women are on average 20% smaller and lighter than men. Women’s pelvises are different from men’s, in order for them to pass the large head of a human baby. Instead of the strong, boxy male pelvis, women have a wide, shallow one, which forces their hips out. The legs have to turn in toward the midline, causing the classic reverse angle at the knee so that their tibias can be more vertical. Women’s upper bodies are very much less massive than men’s, and their shoulders tend to be narrow.

The differences are not just skeletal. There are two types of muscle fibre, one adapted for the explosive release of large amounts of energy and one for repetitive but long-lasting release. Men mostly have the first type, women the second. Normal, healthy women of appropriate weight carry a greater percentage of body fat than any other land animal except polar bears. Far more of their body mass is fat than in men, enabling them to build up reserves to sustain them through childbirth and breastfeeding. Women’s weight is lower down, to help them balance when heavily pregnant and carrying children. Men’s weight is higher up, in powerful muscular torsos perfect for running and throwing, and their high centre of balance lets them knock down a prey animal. There are differences in the brain, too. These are all species characteristics: all humans, everywhere, on average, hold true to this model. In other words, women are morphologically suited to one set of tasks, and men to another; women are indeed, on average, better adapted to gathering and raising children, and men to hunting.

An Essential Part of Human Development

The division of tasks by gender and the consequent establishment of two complementary groups with differing roles and responsibilities was an essential part of human development. Since the underlying function of human society is to continue through reproduction and the survival of the young, which was dependent on women, in matters concerning the home and children they had authority. There was a balance, an equilibrium that allowed the two groups to function independently yet in a co-operative manner. However, the division of tasks exposed men to higher risk of violent death or life-shortening injury. Since age and experience were regarded as important and the elder mothers were probably the oldest and wisest people in the tribe, they were natural candidates for leadership.

Here we see a birth-oriented culture in which the leader, certainly of the home group and probably of the entire tribe, would have been the most trusted mother. She was sacred in her motherhood, respected for her wisdom, knowledge and shamanistic power, loved by and loving the people around her, many of whom would have been her children.

At the same time, a large party making as much noise as possible would be likely to drive off any other predators. So this was a relatively safe form of hunting.

  1. You give a very convincing and well-supported argument for how socially-important tasks devolved onto ‘men and not-men’ for the benefit, survival and reproduction of the group. It would seem that you are working towards a contrast with today’s demand for equality in all things between these two membership groups. I think we are all beginning to see the less fortunate consequences of such demands and I look forward to reading your arguments that seem to be leading to a discussion of this line of thinking. As you well know, it will attract the opprobrium of those who pursue an opposed and currently dominant orthodoxy and brook no deviation from it let alone an open discussion of it.

    1. Hello Ronald

      Thank you. A lot depends on what you mean by ‘equality’. I mean ‘Equality under the law and before the State.’ This should be strict. But no more than that.

      I do not mean ‘equality of outcome’ because that is essentially Marxism and negates any purpose there might be in individual effort. On a whole range of parameters, humans are manifestly not ‘equal’ and there is nothing can change that. I was born with one ball. Are these SJW’s going to magic me another one so that I can be more ‘equal’ to other men? Like hell they are.

      Similarly, I do not believe that it is any business of the State to redistribute wealth. The function of the State is the protection of citizens; I fail to see how that can be achieved by robbing some to give to others. Further, if the State cannot protect the citizenry, why are we paying taxes at all?

      Finally, I hear a lot of feminists and other juvenile pests going on about ‘safe spaces’. Yet these very people have been doing away with safe spaces for decades. What happened to all the Gentlemen’s Clubs where one could be free of the irritation of women? Golf Clubs? The good pubs where you could go for a pint and a scratch of the arse accompanied by a game of darts? Women have invaded every single safe space that existed for men, and now they want, by the way, to establish safe spaces where ONLY women may go.They want to REESTABLISH segregated schools. Talk about hypocrisy? Feminism is steeped in it. OK, fine, let them have their ‘safe spaces’ as long as we can have our clubs and our pubs and all the other female-free zones back.
