Did Testosterone and Female Breasts Drive Evolution? Posted on: 2003-09-24 22:35:16 [ Printer friendly ]
James Michael Howard has put forward the thesis that testosterone and other hormones are major forces in human evolution, a theory with numerous racial, sexual, and eugenic implications. "Testosterone is known to increase sex drive in both males and females. This would increase the percentage of higher testosterone hominids with time. Increased testosterone would reduce hair, increase sweat glands and activity and, in the female would reduce labial displays, normally dependent upon increased estrogen to testosterone. The exposed breast, also indicative of sexual maturity, would become the primary sexual display. This combination would eventually lead to bipedalism. Other events, dependent upon the hormones DHEA and melatonin, would, much later, result in an enlarged brain." (image: Psyche, by Arno Breker)
"As testosterone increased in hominid females, along with upright locomotion and reduced hair, competition among females must have increased, especially with increased sex drive. I suggest this produced a selection pressure for development of the breast as a primary sexual attractive device; the same mechanism that produced the estrus display in chimpanzees. We are the only group of mammals that use the breast as a sexual display. Breast development is directly tied to the abundant form of DHEA, called DHEA sulfate, from which DHEA is made."
"My work suggests testosterone increases periodically in civilizations. That is, where food and shelter are beneficial, people of higher testosterone will increase rapidly, compared to low testosterone people. They are more sexual and impulsive; they make more babies."
"Testosterone will increase in a group, because it increases sexual opportunity. Aggressive, high T males force less aggressive, less massive males away from females. Over time, therefore, T increases in hominids and pongids; this is the driving force that causes all lines in the chart above to move to the right, i.e., increased size. This is supported in the fossil record; early Australopithecines were smaller: '...it is notable that the more ancient Australopithecines had thin skull bones and only modest protuberances on his cranium' (Encyclopædia Britannica 1984; 8: 1033.) Eventually, extremely massive males, such as Australopithecus robustus and A. boisei, were produced. These species became extinct without contributing to the hominid line; too much testosterone is a bad thing."
"Children are reaching puberty earlier with each generation, and early puberty arrests final development of the brain. This means that, on average, our advanced brain is increasingly underdeveloped with each generation. This is why so many children cannot control their sexual or aggressive impulses. It is fact that, on average, the behaviors mentioned above, occur in higher incidence in the black population."
