Male chimpanzees exchange meat for sex is the headline but it is really an argument for human commitment to relationship, and responsibility on the part of the male, as well. Male chimps that are willing to share the proceeds of their hunting expeditions mate twice as often as their more selfish counterparts. "By sharing, the males increase the number of times they mate, and the females increase their intake of calories," said Dr Gomes.
"What's amazing is that if a male shares with a particular female, he doubles the number of times he copulates with her, which is likely to increase the probability of fertilising that female."
As mankind moves away from the primate origins, the primates seem to be moving forward to emulate man, with primitive tools and behaving purposefully to get what they wan, more offspring. Whoops, man went over the curve on that one and wants more sex but fewer children. While instinct still reigns to make mankind want toimpregnate every fertile female, the current laws which demand that those men remain fiscally responsible for those offspring seems to have that instinct gradually evolving to extinction.
