Surely, speech more disruptive than genes?

"The story of human migration is very expansive and inexact," wrote C Rajghatta. "It is agreed on the basis of reasonable evidence that humankind took its first outbound steps from Africa to Asia." It is now accepted that several types of human species evolved at around the same time and probably reproduced with each other until finally Homo sapiens took over the world. So, "...it would seem Native Americans are of Asian stock, and even before that of African stock, because everything flowed out of the Rift Valley. In that sense, we are all black." True, but if you go back even further we are all bacteria, and further back than that we were just amino acids. Rajghatta is making the point that since we originated from the same genetic stock we must not differentiate between races. "Of course, you can't expect white nationalists in the US and hypernationalists in India -- which is also periodically in the throes of nativism -- to absorb or process all this." In short, nationalists are racists. This has been taken even further by the concept of gender neutrality, in which men and women are the same and any difference that we see is because of the way we are brought up. Problem is that humans are genetically very close to chimpanzees, and, although men are 99.9% similar to each other, we are only 98.5% similar to women. Which means that the difference between men and women is 15 times greater than between two men or two women. Mathematics is racist, wrote R Gutierrez, Professor of maths at the University of Illinois. "School mathematics curricula emphasizing terms like Pythagorean Theorem and pi perpetuate a perception that mathematics was largely developed by Greeks and other Europeans," she wrote, "On many levels, mathematics itself operates as whiteness." The concept of 'zero' arose in Mesopotamia but was first used as 'sunya', or 'nothingness', in India. So are we genetically similar or different? This kind of debate led to an evil social experiment, in which triplets were separated at birth and given to different families to bring up. They found each other as adults and even started a business together, but could not adjust, and one brother committed suicide. So, on the one hand, men are same as women and all races are the same, but, on the other, identical twins are not the same, it's all nurture. This kind of discussion is futile. The difference in human beings is because of culture, which comes from speech, spoken, written and numerical, which lead to music, literature and art. The development of science and the theory of evolution have not been able to eradicate religions, which are held responsible for most of the strife in today's world. Human beings are social animals and like to belong to groups which are culturally similar. It is nothing to do with genetics.
