Evolutionary theory of Patriarchy

Patriarchy has always surprised me. Why should one gender class, the females surrender almost everything at the feet of males? Was it always like this? Is it changing? Let me try to find some answers.

There is no definite evidence to show when Patriarchy originated, or whether it was present even before Homo sapiens were evolved. Many other animals including many of the non-human primates exhibit patriarchy. But many other species of both primates and non-primates do not exhibit patriarchy. This shows that as different species evolved differently they adhered to different systems regarding Gender relations.
 As per evolutionary anthropology there is a natural selection of behaviour which gives the species maximum survival benefit.
In case of early Homo sapiens specialisation into a section  who hunt and a section which do not hunt but only gather food is an important change from rest of primates which helped in its survival. The human baby needed adult care and support for a long time compared to other species. This meant many of the women were not available for going out to hunt. Also the increased physical strength exhibited by males might have been more suitable for hunting. Thus hunting more or less became the domain of males while child rearing and gathering the domain of females.
 Many believe that compared to most other species humans exhibit the strongest male to male bonding. This might have been the result of group hunting of large animals several times the size of humans. At the same time humans show the least female to female bonding. May be the way of life of a gatherer might have been to see a competition in every one else.
As the hunter-gatherer society evolved, incest taboo that prevents sexual act between close relatives resulted in females going out to join other groups. Many of the non human primates shows same behaviour,though in some others it is the males who go out of the parental group.

Why women went out and not men? Is this again because of the strong male to male bonding in humans?
 In most of the primates where females go out of their parental group (chimpanzees,hamadrayas baboons), patriarchy is very strong. One reason for this is it is difficult for the new-comer female to make any sort of bonding with females of her adopted group.

In contrast in some species, females remain in their birth communities their whole lives. Here females  form alliances against aggressive males. Vervet monkeys  macaques, olive baboons, patas and rhesus monkeys are examples for this 'female bonding' . Thus in these species the males behave with much more respect towards females.

As human society developed from hunter-gatherer system to cultivation and feudalism patriarchy became stronger. Surplus wealth created had to be transferred to off springs. But if it had to be given to girls who go out of the house in marriage also,it meant  diluting of the family wealth. So a male only inheritance was developed for the survival advantage of the family as a unit but at a distinct disadvantage to females.

 Why females agreed to this?  By then men had almost complete control over tools for production of wealth like land,agricultural implements, weapons,domestic animals etc. It was also men who went out to wage war to capture more land and slave labourers.Women  might have perceived that their interests is best served through alliances with men, not with other women.

 Feudalism was slowly replaced by Capitalism due to the scientific revolution and advent of mass production of goods. Joint families got disbanded as they could not survive the new economic system.  Women who were small scale producers of goods with in the joint family system became either confined to household work or had to go out to work in factories. As production became more and more mechanised the importance of physical strength in production diminished. But still women who did the same work as men were under paid by the Capitalists.  Thus even though Capitalism helped in reducing gender discrimination by allowing women to sell their labour in the market, it was at a lower wage and  the unpaid house work and child rearing still remained the sole responsibility of women. When ever family needed more of her unpaid work, she had to sacrifice her paid work.

 Change in economic system to Capitalism also resulted in change in political system. More and more Nation states were formed and monarchies were replaced by democratic system of  governance. Initially only the rich men were able to contest or even  vote. Great struggles by working classes and women forced the ruling capitalists to allow universal franchise.  Legislators passed many gender sensitive laws.
 Thus now in most of the countries legally there is not much gender discrimination. Even there are positive discrimination for women in many ways. But still women are discriminated widely in the society though much less than before.
 Study of animals shows us that female to female alliances and alliance with like minded oppressed males are important in creating more egalitarian societies.
  Let us hope that such an alliance of oppressed classes can create not only a gender-equitable but also a social-equitable society in near future.

Darwin 200: Let us remember a great Scientist and a revolutionary theory



Today the World is celebrating the bicentenary of the birth one of the greatest Scientist it has ever seen, Charles Robert Darwin (1809-1882).

His theory of evolution by natural selection, now the unifying theory of the life sciences, explained where all of the astonishingly diverse kinds of living things came from and how they became exquisitely adapted to their particular environments. Darwin demonstrated that the difference between humans and other animals is one of degree not kind. Darwin's writings produced profound reactions in geology, zoology, taxonomy, botany, palaeontology, philosophy, anthropology, psychology, literature and theology, many of which are still ongoing.
Darwin presented compelling evidence for evolution in On the Origin of Species [1959] and, since his time, the case has become overwhelming. Countless fossil discoveries allow us to trace the evolution of today's organisms from earlier forms. DNA sequencing has confirmed beyond any doubt that all living creatures share a common origin. Innumerable examples of evolution in action can be seen all around us, from the pollution-matching peppered moth to fast-changing viruses such as HIV and H5N1 bird flu. Evolution is as firmly established a scientific fact as the roundness of the Earth.





And yet despite an ever-growing mountain of evidence most people around the world are not taught the truth about evolution, if they are taught about it at all. Even in the UK, the birthplace of Darwin with an educated and increasingly secular population, one recent poll suggests less than half the population accepts evolution. Even lesser number of US citizens believe in it.In US controversy regarding Creation and theory of intelligent design continues. Many Islamic Countries[Saudi Arabia,Sudan] do not teach it in Schools.


Some misconceptions about Evolution


Evolution must be the best-known yet worst-understood of all scientific theories. Here are some popular misconceptions


Natural selection explains everything we see today
There are two fundamental mechanisms of evolution. Natural selection is only one of them. The less realised mechanism is the random genetic drift. The anti-evolutionists fail to recognise genetic drift. Darwin did not know about it either.
Genetic drift is the random change in the genetic composition of a population due to chance events. It all boils down to how the two alleles, one inherited from each parent, get affected. The smaller a population, the bigger the role of genetic drift.


Evolution always increases the chances of survival


The theory of survival of the fittest is widely misunderstood.
Evolution does not always increase the chances of a species’ survival. Mutations, which provide the vital mechanism for natural selection, need to be helpful.
Detrimental mutations are a common phenomenon. Species may not survive if such mutations happen rapidly and if they keep accumulating.
Again, if the rate at which mutations happens is slow, then a species may not be able to cope with changing environmental conditions.


'Survival of the fittest' justifies 'everyone for themselves'


Fittest does not always go with the most aggressive or strongest species. On the contrary, the ‘fittest’ label may be more appropriate to animals that are the most co-operative like the bees, the best camouflaged or the cleverest. The "fittest" can be the most loving and selfless, not the most aggressive and violent.
The ‘lowly’ sponge and the jellyfish with a few simple cell types have persisted from the Precambrian, and have changed very little. It is the same with fungi, mosses, sharks, and horseshoe crabs.


Man occupies the pinnacle


Till recently scientists believed that “modern invertebrates, fish, amphibians, reptiles, birds, mammals and humans were living representatives of successive evolutionary steps toward a more complex brain,” (Scientific American, December 2008).
But the fact is that complex brains — and sophisticated cognition — have evolved from simpler brains multiple times independently in separate lineages.
This can be seen in molluscs such as octopuses; in bony fishes such as goldfish and, separately again, in cartilagenous fishes such as sharks and manta rays; and in reptiles and birds.

On his birthday today let us applaud the contribution of this great scientist to humanity.
