Because Experience Matters

"Male chimps, unlike their human counterparts, show a distinct sexual preference for females on the riper side of life, an American anthropologist reported in a paper.

Contrary to his own expectations, Martin Muller of Boston University found after years of observation that male chimpanzees consistently sought out the oldest females within a troop for sexual intercourse.

The startling discovery — especially when contrasted with the sexual proclivities of humans, a close evolutionary cousin — suggests that socialization plays a larger role in male-female relations than is commonly assumed.

Given this common ancestry between chimps and Homo sapiens, "the masculine preference for young women is a derived human trait, probably due to the tendency to form long-term relationships between couples," Muller and his co-authors concluded.

The rest is here.
