摘要
最近，科学家们对大约二十只成年野生黑猩猩进行了跟踪研究，发现在野生黑猩猩种群中存在以肉换性的行为。这就意味着，与雌猩猩分享食物的雄猩猩能够获得更多的交配机会，从而大大有利于繁育后代。黑猩猩是世上现存的与人类亲缘关系最近的物种，这一发现揭示了黑猩猩种群与人类狩猎采集社会的关联——无论是人类还是黑猩猩，生存的强者都有更多繁育后代的机会。
The oldest profession isn＇t restricted to humans. A new study found that wild chimpanzees exchange meat for sex.
By stealthily following a group of about 20 adult chimpanzees in GSte d＇ Ivoire＇ s Ta ？ National Park, behavioral ecologists Cristina Gomes and Christophe Boesch of Max Planck Institute for Evolutionary Anthropology in Germany carefully noted which male chimpanzees copulated with which females. The researchers found that she-chimps put out more often for males that shared food with them at least once, compared to stingy males who never offered meat.
