Our tribal nature

Since Sex at Dawn, it is finally beyond doubt that humankind is not a monogamous creature. Nonetheless, there are lot of details still to be filled in as regards the exact role of sexuality in the social organization of our species, both past and present. In this regard, we are only possessed at present of a few, tantalizing clues. However, both brief introspection and sheer logic suffice to conclude that sexual behavior in our species does not serve simply or primarily as some kind of casual, diffuse and undifferentiated social glue. Such an extreme view appears to be a gross simplification even for bonobos.

What I have observed, purely from self-study and from listening to others who have similarly tried to understand themselves, is that there remains a fundamental difference between men and women as regards their emotional response to situations in which their sexuality comes to contemporary expression, at least when it is expressed within a holistic response to another individual where attraction is felt on a number of levels. This difference appears to me to be irreducible to purely cultural and contingent factors, and to play a plausible role in primitive societies as well.

Sticking to bonobos, and we should be careful in extrapolating too naively to our own species, we know that they live in philopatric groups. This means that the male composition of groups is constant over time, whilst females migrate into groups other than that in which they were born. Whilst homosexual behavior takes place in both sexes, it appears to play more of a bonding role amongst females, whereas amongst males its role is more as an outlet for sexual tension and to reinforce mating hierarchies: males exhibit markedly less intra-sex solidarity than females.

Now I have not read anything about this, applying either to bonobos or our own species, but the question obviously arises of the factors which come into play in inciting a female to join another group. There is clearly a push factor – the desire to avoid incestuous pregnancy – but it is still necessary to choose the new host group. It is hard to believe that this choice is entirely left to chance.

Looking at our own species – methodological rigor is not claimed – and trying to think a little bit how this would have worked in primitive tribal societies (though contemporary evidence should also be available), I have remarked and postulate that men, when they feel a high degree of attraction to a new female (“fall in love”), seek to bring her into the tribe. “Falling in love” does not cause men to wish to abandon their existing family and other social ties, though it may be so strong on occasion and encounter such opposing forces that this less-preferred option nevertheless comes out on top. Essentially, male sexuality is inclusive. Males also have a strong wish for new females to bond with existing females and will make efforts in this sense, however fruitlessly and apparently, perhaps, naively. Bonding with existing females will be a factor in the ultimate inclusion or otherwise of a new female in the group. Translated into contemporary society, the bottom line is that men do not want to leave their wives (never mind their children), but at the same time do wish to offer protection and security to new sexual partners as well.

On the female side, other forces are at work. A woman who feels a deep attraction to a new man is likely to feel a desire to be with him, and to consider abandoning her existing social roles in order to realize that goal. The frustration of this desire can result in dramatic behavior,  à la Madame Bovary. It is nonetheless held in check by certain factors, principal amongst which are children and female friends. To leave her existing mate is less inconceivable for a woman than for a man and sentimental ties are less important relative to the force of her new passion.

In bonobos, for a female to leave a group would mean to leave her immature children behind. The males will never rejoin her, and the females, once they enter into adulthood, are unlikely to. I do not know if females ever produce children in more than one group but am guessing it is most uncommon. It’s likely that a female who has become a mother remains henceforth with the group in which that event has occurred. Romantic attachments to extra-group males, whilst they might still happen, would not achieve the critical momentum necessary to sever existing ties. Female sexuality eventually settles into a more nurturing and more inclusive form, but the initial choice of group is made on the basis of a single male considered as a desirable mate – not on the basis of an assessment of the group as a whole.

This postulate shows us how what we now consider as “monogamous” sexual attraction may have existed and played a role in the social processes leading to the formation of primitive tribal groups, in particular to resolve the problem of choice of group faced by the newly adult female. In this perspective, it is not something anomalous grafted onto a fundamentally polygamous nature. When, however, it encounters contemporary social structures, it misfires for several reasons.

Our existing “tribes” are tiny nuclear families or, at best, kinship groups. Woman have been given legal rights (without my taking any view on these rights) which make it likely that separation from children will not be a cost of divorce. Under these circumstances, leaving the “tribe” is much easier. This creates a risk of breakdown in the tribe which a man’s efforts to strengthen the tribe by bringing in new females and new children may only hasten. The same drives which developed, in other words, to generate stable social structures under the constraint of maintaining genetic diversity, now generate unstable social structures in which childcare inevitably suffers.

This picture is not, perhaps, as hopeless as it sounds. In primitive times also, many factors would have frustrated the wishes of many individuals, and yet these factors would not have led to massive neurosis and social breakdown. We are far more robust to disappointment than we perhaps realize.

That certain desired outcomes cannot be realized is not in itself the problem. The dramatically dysfunctional outcomes that we see all around us are rather due to the fact that we cannot even own the truth of our nature and respect that of the other. Under these circumstances, it is not only particular wishes that cannot be accommodated, but the whole prospect that such wishes will be accommodated, ever and to any degree. This systemic, existential frustration generates ill-feeling and potentially violence and abuse which goes on to undermine our tiny tribes from inside, making their undermining from outside ever more probable.

As ever, a wise and adaptive response can only come through awareness and empathy.
