Quote by Melvin Konner

“There is a birth defect that is surprisingly common, due to a change in a key pair of chromosomes. In the normal condition the two look the same, but in this disorder one is shrunken beyond recognition. The result is shortened life span, higher mortality at all ages, an inability to reproduce, premature hair loss, and brain defects variously resulting in attention deficit, hyperactivity, conduct disorder, hypersexuality, and an enormous excess of both outward and self-directed aggression. The main physiological mechanism is androgen poisoning, although there may be others. I call it the X-chromosome deficiency syndrome, and a stunning 49 percent of the human species is affected. It is also called maleness.”
