This also explains why some of our closest relatives in the animal kingdom suffer from hair loss. With the women now outnumbering the men, men got to be more choosy about which mate they selected. But of course, there are bald black men and bald Asian men, too. Because of that stress, their bodies created more cortisol, which in turn lowered their testosterone levels. Then, in a few thousand years, some curious gorilla with a laptop and a receding hairline may investigate why it is so many of his fellow apes are also going bald.

The stresses of prehistoric life may also have contributed to the persistence of baldness in yet another way.

Did Otherwise Hairy Cavemen Suffer from Male-Pattern Baldness, Too?
Then, in a few thousand years, some curious gorilla with a laptop and a receding hairline may investigate why it is so many of his fellow apes are also going bald. Ryan explains that there are genetic markers for male-pattern baldness that are found in Europeans, but not in Asians or Africans, which means that these genes originated after humans migrated to Europe some 40, years ago. This is in contrast to places like Africa, where the population was more even and thus mating rituals were a little more balanced. In this way we likely stalked large prey animals, pursued them on foot with our more efficient bipedal form of locomotion and then, after they overheated and stopped, our Homo erectus ancestors caught up with them and killed them.
