Why do men have a television?

That part reminds us that gender is something that is clearly transparent, even before birth. No matter what gender you are, everyone starts to be female in the womb.

During the first few weeks of birth, the embryo will carry the female mark, from the genitalia to the nipple. Only after 60 days of development, does the male hormone testoterone appear, altering the genetic activity of the cells in the genitals and brain. But the vestiges of the nipples are not lost anywhere.

So the question is: Why is the male head still connected to nerves and blood vessels? In many mammals, the formation of a nipple in a male is stunted by hormones, but not in humans. Will ancient men raise children? Evidence is not. It is possible that such harmless growth tips have not been eliminated by natural selection, the researchers said.
