    Human-like altruism shown in chimpanzees





    Debates about altruism are often based on the assumption that it is either unique to humans or else the human version differs from that of other animals in important ways. Thus, only humans are supposed to act on behalf of others, even toward genetically unrelated individuals, without personal gain, at a cost to themselves. Studies investigating such behaviors in nonhuman primates, especially our close relative the chimpanzee, form an important contribution to this debate.

    This week in PLoS Biology, Felix Warneken and colleagues from the Max Planck Institute for Evolutionary Anthropology present experimental evidence that chimpanzees act altruistically toward genetically unrelated conspecifics. In addition, in two comparative experiments, they found that both chimpanzees and human infants helped altruistically regardless of any expectation of reward, even when some effort was required, and even when the recipient was an unfamiliar individual—all features previously thought to be unique to humans.

    The evolutionary roots of human altruism may thus go deeper than previously thought, reaching as far back as the last common ancestor of humans and chimpanzees. In a related article, Frans de Waal discusses the issues brought out by this discovery.

    Trong khi khỉ nó c̣n giúp đỡ những động vật khác loài của nó.. th́ đám dă nhân người Việt lại đi hại, cướp của đồng loại; mà c̣n đi cướp của của người nghèo, người đói, người có con nhỏ không đủ ăn uống.. Để chúng có thể xây nhà to, cữa lớn.

    Phải gọi lũ dă nhân Việt là ǵ!!!!!!!
