From a genetic point of view, this point could be the origin of modern humans.
All animals have unique variations in genes from individual to individual.
This variation can be meaningless, or can make the difference in, for instance, susceptibility to disease. They also looked at bonobos, commonly known as pygmy chimpanzees. They looked at one gene called Xq13.3, which is found on the X chromosome, one of the two chromosomes related to sex. It has no known function, but it is known to have a low mutation rate and has been well studied in people. They found Xq13.3 has almost four times as many variants and is three times as old in chimps as in humans.
