By Colin Barras. Humans, meanwhile, show a variety of mating behaviours but often form monogamous couples. Michael Jensen-Seaman and Scott Hergenrother at Duquesne University in Pennsylvania think that it is the chimps — not humans — that have experimented with new sexual behaviours since our lineages diverged. But did male chimps inherit their mating plugs from the last common ancestor they shared with us or did they evolve it later? They found that the enzyme is four times as abundant in human semen as it is in chimp semen. The change is related to the way the ACPP gene is turned on and off. For clues about whether the human-chimp ancestor had similar levels of the enzyme to humans or chimps, the team turned to gorillas. The gorilla lineage separated from the human-chimp ancestor a few million years earlier, so offers a perspective on mating habits in the human-chimp ancestor. The analysis showed gorillas regulate ACPP in the same way as humans, suggesting that the human-chimp ancestor did as well.

After the ordeal the alhaji went to drop her and drove off, few hours later she started complaining of stomach ache, she thought it was normal thing, but from what we gathered fews hours later, maggots start coming out from her private parts, her friend tried to rush her to the hospital but it was too late…………. She died before they could do anything. That's a pretty expensive hooker for a monkey with a maggot STD. Makes me feel bad for my choices. How do we know that the maggots were from the monkey? I mean, look at that ass, there could be anything in there. They need to make sure they thoroughly check that thing. Who knows how many secrets are in there. I swear I could see Hoffa's shoe sticking out a little bit.

Male chimps apparently can win over the opposite sex with the aid of fruit stolen from nearby farms and orchards. The discovery could shed light on the evolution of the sharing of food and more complex behaviors among humans, Hockings added. Over the course of a year, Hockings and her colleagues investigated how wild chimpanzees coexisted with people at the West African village of Bossou in the Republic of Guinea. They're the totem of the village, so people don't kill them," Hockings told LiveScience. The researchers found male chimps often pilfered crops, especially targeting papayas. They also took bananas, oranges and pineapples, as well as rice, maize, cassava, okra, sugarcane and cacao. The chimps typically looked nervous while raiding crops, scratching themselves often. Males especially chose to share food with a preferred female, one who took part in the most "consortships"—where she spent time alone with a male so he got an exclusive chance at sex. These findings could shed light on how the sharing of food and more complex behaviors developed among the ancestors of humans.
Though chimpanzees and humans share about 99 percent of the same DNA, numerous physical and behavioral traits separate us from our closest living relatives. But are we different even when it comes to sex? Just how do chimpanzees "do it?
