Blood Relations: Menstruation and the Origins of Culture

Every generation of Marxists has to fight its battle against those who produce the latest proofs – strangely enough, always the same old proofs – that Marxism is finished. But we have also had, repeatedly, to fight another, even more tiresome battle against people who claim to be on our own side. Ever since Herr Professor Dühring beguiled half the intellectuals of the German socialist movement with his ‘revolution in science’ in the 1880s, Marxists have had to expose a series of intellectual quacks who have tried to present their pet systems of myths and half-truths as the latest thing in scientific advance.

Chris Knight’s book about the origins of human culture falls straight into the same tradition of quackery. Every chapter is headed by a quote from Marx. But the intellectual basis of the book owes little to Marx’s insistence that social production is the key to the development of humanity. Rather Knight acknowledges his debt to: ‘sociobiology’s achievements’ in seeing that ‘what animates ... the flesh and blood individual ... are ... genes ... whose only law is to survive ...’; to the mystical poets Peter Redgrove and Penelope Sharp, whose ‘style and tone’, he tells us, is ‘Jungian’; to those ‘involved in the Greenham Common anti-missile campaigns of the early 1980s’ who refused ‘to collaborate in the whole masculinist political set up ...’; and to his ‘political friends’ which include prominent Labour MP Ken Livingstone and two lesser known luminaries of the London Labour left, Keith Veness and Graham Bash.

His politics are those of the Labour left of a decade ago – when Knight himself edited the ‘personal politics’ section of Labour Briefing, mixing Greenham Common feminism with municipal socialism – and his methodology is similarly eclectic. The resulting confusion leads to absurdities like speaking of a ‘class conflict ... between genders’ among ‘monkeys and apes’.

Most pop sociobiologists do not go beyond the 17th century mechanical materialist, Thomas Hobbes, who described life for humans in the ‘state of nature’ as ‘nasty, brutish and short’, with a ‘war of all against all’ making the development of civilisation impossible until people were forcibly compelled to behave themselves. Knight is no exception. He argues ‘genetic imperatives’ necessarily caused continual, bitter, bloody competition among our primate ancestors. Their behaviour, like that of present day primates, he describes as like ‘primitive capitalists’, their battles with each other as reminiscent ‘of some of Lenin’s descriptions of inter-imperialist rivalry’. And this prevented any real development of culture among our ancestors until about 50,000 or 60,000 years ago when co-operation replaced conflict.

His ‘theory’ is a Just So story about how such a change could have occurred – instead of telling how the elephant got its trunk, it claims to tell how humans got culture. It depends on adding a number of dubious claims to the initial postulate of endless conflict.

Firstly, males and females of all species are said to have different ‘genetic imperatives’. Males can have innumerable offspring if they can squirt their sperm around widely enough, while females are restricted to those they carry inside their own bodies. So the genetically successful male will always be the one that fights other males for ‘dominance’ over as many females as possible and does nothing to help in the upbringing of progeny. But the genetically successful female will pay attention to rearing her offspring. In this way the motherly female and the philandering male are genetically fixed, and males, given the chance, will behave as parasites and oppressors, a ‘leisured class’, lording it over an exploited class of female reproducers. These, suffering from the incessant competition of animal society, have an interest in bringing about its revolutionary overthrow.

Secondly, human beings differ biologically from other primates in a way that alters the balance of power between the sexes, without changing the fundamental genetic disposition of either sex. The oestrus cycle, in which the female is only ‘on heat’ and of sexual interest to the male at the time of ovulation, is replaced by the menstrual cycle, with sex possible at all times – except, according to Knight, at the time of menstruation itself, when it is a fairly bloody business.

Thirdly, late on in human evolution women apparently discovered how to take advantage of this by synchronising their periods so as to deny men sex until they went out hunting and returned to share the catch with them. Such a ‘sex strike’ forced the innately competitive males to co-operate to the benefit of the females and of humanity in general.

Fourthly, all this allegedly triggered off the development of culture and language some 50,000 to 60,000 years ago.

Finally, the myths and taboos of ‘traditional societies’ are said to bear witness to this today. They re-enact elements of the sex strike by forbidding sex or cooking during menstruation, by banning hunters from eating their own kill, and by extolling the moon. Their tales of wondrous snakes or dragons are a celebration of women’s power and solidarity, even if this has since been usurped by men. ‘Such beliefs are in essence good science.’

This equation of myth with science is based on a linking together of half-truths, false generalisations, unproven assertions and the occasional fact.

Take Knight’s initial presupposition, the alleged, state-of-nature, bloody competition between male primates over food and females. Knight justifies himself by reference to Solly Zukerman’s study of the chimps in London Zoo in the early 1930s. But there have been scores of further studies since, many based in the wild, which give a very different picture. [1] They reveal differences of social behaviour between different ape species as great as those between any of them and modern humans. [2] And in many cases there are far more instances of cooperation between individuals than conflict.

The social life of chimps, and still less gorillas, is certainly not one of endless battles by males to dominate females. [3] Cases of aggressive behaviour do occur among chimps – but they are not all pervasive and only occasionally end in fights. [4] Nor are there continual fights over food. When common chimpanzees make ‘occasional forays into meat eating’ they ‘share out morsels among individuals who beg persistently enough’. [5] With pygmy chimpanzees, ‘Food and feeding are a focus for social interactions ... Plant food is frequently shared.’ [6]

And any hunting is, itself, likely to involve co-operation between different members of the chimp group – and not only the males. It involves action that ‘implies a lot of restraint, a good deal of cooperation, and not a little communication’. [7] So much for Knight’s most basic sociobiological postulate, that cooperation was impossible until the ‘sex strike’! With it his whole construction collapses. Every other point of his argument is similarly flawed.

  1. ‘Genetic success’ for individual males does not, in all situations and at all times, depend upon males ignoring the interests of everyone else. To say the most successful genetic strategy will be to fertilise as many females as possible, rather than helping one female rear her offspring, is rather like saying a successful gambling strategy always involves putting small sums of money on many horses rather than the lot on a near certainty. Of course it doesn’t. It all depends on the odds. If material conditions mean an unaided female will almost certainly lose her offspring to predators or through starvation, then any male who fails to help with child rearing will not be able to pass on his genes. ‘Survival of the fittest’ will then be the survival of the most fatherly. As Gigliari tells: ‘In many species of mammals, the parental investment by males is considerable, and apparently enhances the reproductive potential of both sexes.’ He refers to Callicebus monkeys, white handed gibbons, wild dogs, wolves, and Hartman Zebras. [8] I don’t think Knight would want to argue a sex strike had to take place in all these cases!
     
  2. Human females are not unique in the replacement of the oestrus cycle by the menstrual cycle or in their readiness for sex at any point in the cycle. ‘The menstrual cycle is a process common to old world monkeys, apes and men’ [9] and, as a result, ‘In anthropoid apes the sexual cycle is not expressed nearly as markedly as in other animals’. [10] Among chimps ‘mating may occur at any time during the female’s cycle’ although ‘significantly more sexual behaviour occurs during the follicular phase’ [11], ‘orangutangs mate throughout the female’s menstrual cycle without pronounced cyclical changes in behaviour’ [12], and gorilla ‘females may present themselves to males throughout the cycle, but males accept a greater proportion when the female’s labia are fully swollen’. [13] Among both chimps and gorillas, it can be either males or females who take the initiative sexually. [14] Knight’s picture of the philandering male, driven by an overpowering instinct to fight other males to fertilise as many females as possible, hardly matches up with the facts.
     
  3. Sychronisation of periods among females in close contact with each other is not, as Knight claims, an adaptive mechanism specific to humans which can explain some sudden invention of culture a few thousand years ago. It occurs among rats, gelada baboons, hamadryas baboons, rhesus monkeys and chimpanzees. [15] What is more, it is certainly not a conscious mechanism, as is implied by talk of women choosing to synchronise periods to go on ‘sex strike’. It is a completely unconscious process, arising as physical stimuli, probably of an olfactory nature, cause changes in hormonal balances. [16]
     
  4. There is overwhelming evidence for the existence of culture and language long before Knight’s 50,000 to 60,000 years ago. Stone implements have been found that are more than 2 million years old [17] and by half a million years ago they were being designed according to common patterns. By the time of the neanderthals, 200,000 years ago, there is evidence of ritual burial. There was already a marked growth of the parts of the brain responsible for speech in modern man – Broca’s and Wernicke’s – in homo erectus 500,000 to 1,000,000 years ago (and possibly in homo habilis more than a million years before this) [18], while the vocal organs of the neanderthals would have been able to make most of the sounds we can. [19]

    All this suggests there was a long drawn out development of symbolic culture and language out of rudimentary sounds and gestures similar to those used by chimps and gorillas today. There would have been all sorts of quantitative changes and qualitative leaps at different points during the 2 million years of this development, as humans evolved larger brains and learnt new ways of using them – archaeologists have long distinguished between the different ‘cultures’ that characterise tools to be found at different times in this long history. But this does not at all mean that humans accidentally managed to quadruple the size of the primate brain over a 3 or 4 million year period before suddenly 50,000 to 60,000 years ago discovering how to use it.
     
  5. Among many surviving hunter-gatherer societies – those closest in their lifestyle to our ancestors of 50,000 to 60,000 years ago – myths and taboo are not all what Knight’s model demands. He himself admits, ‘It is certainly not the case that [Australian] Aboriginal women everywhere synchronised their periods with one another or with the moon in the recent pre-contact period’, and that ‘we have little hard evidence for either the presence or absence of real menstrual synchrony among the hunter-gatherer peoples of Africa’.

Nor are menstrual taboos by any means universal in such societies. The Mbuti pygmies of the central African rainforest ignore the strict menstrual taboos that prevail among their agricultural Bantu neighbours [20], while the Kung regard menstruation as a relatively minor event. [21] So desperate is Knight for evidence that he claims painting the body red has menstrual significance. Does he apply that to all women who use make-up? As for his other great taboo, the ‘first kill’ one, Knight himself writes that it is ‘not always rigidly adhered to’, that ‘it is in fact systematically evaded or undermined in a multiplicity of historically determined ways’. Put more simply: it does not apply universally as he claims!

What we are faced with in this book, then, is a series of phoney facts linked together by an intricate cobweb of speculation and then dressed up as ‘Marxism’. This is particularly regrettable since there has developed, in recent years, a body of evolutionary theory among a minority of archaeologists and anthropologists that fits in with what genuine Marxists have long argued. [22]

The starting point of this approach is to recognise that in certain situations natural selection favours groups whose genetic make-up enables them to learn from each other, co-operating to get a livelihood. This happened some millions of years ago among certain ape like creatures. Faced with climatic changes different groups of this species responded differently. While the ancestors of the gorilla and the chimp adapted to forest and woodland life, our ancestors were able to survive in savannah (open grassland dotted with clumps of trees) because three characteristics present in all African apes became more marked in them – the ability to stand upright, the ability to co-operate in gathering food and the ability to make rudimentary tools.

Their mode of existence gave selective advantage to traits – both biological and cultural – that only exist in embryonic form in other primates: co-operation, the use of the hand to make and carry tools, the development of communication through gesture and voice, the detailed observation of animal life to be hunted and plant life to be collected, increased concern with the socialisation of the young while they learnt from their elders, the establishment of friendly links with other groups through intermating.

What we have here is the beginnings of a labour theory of human origins and of culture, something which then enables us to begin to explain other epochal changes in human existence, like the rise of agriculture, the growth of a surplus, and the origin of classes, the state, systematic warfare and women’s oppression. A few of those who practise this approach are conscious Marxists. Most are not. But they are driven to materialist conclusions by the desire to explain the factual material they have discovered about the history of humanity. We can learn a lot from them – providing we are not put off the whole topic by Knight’s menstrual moonshine.
