    Wakuu nimeshtuka kusikia kuwa chimpazee nao wanapenda sana kale kamchezo ka wakubwa, wako tayari kuhonga windo lote ili apate. Wanyama wengi sayansi inatuambia wanafanya hako kamchezo kwa ajili ya kuzaliana tu, si kujifurahisha, naona hawa nao wamo katika wale wachache au kwa kuwa ni karibu binadamu?. Hiyo si yangu, ni watafiti soma hapa:
    BBC NEWS | Science & Environment | Chimpanzees exchange meat for sex

    Chimpanzees exchange meat for sex
    By Victoria Gill
    Science reporter, BBC News

    Male chimp shares meat with female
    Share and share alike: a male chimp will give up his hard-earned catch for sex

    Chimpanzees enter into "deals" whereby they exchange meat for sex, according to researchers.

    Male chimps that are willing to share the proceeds of their hunting expeditions mate twice as often as their more selfish counterparts.

    This is a long-term exchange, so males continue to share their catch with females when they are not fertile, copulating with them when they are.

    The team describe their findings in the journal PLoS One.

    Male chimp with meat
    Meat is an important, protein-rich food for chimpanzees

    Cristina Gomes and her colleagues, from the Max Planck Institute for Evolutionary Anthropology in Germany, studied chimps in the Tai Forest reserve in Ivory Coast.

    She and her team observed the animals as they hunted, and monitored the number of times they copulated.

    "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."

    High value

    Meat is important for the animals' diet because it is so high in protein. Since female chimps do not usually hunt, "they have a hard time getting it on their own," explained Dr Gomes.

    The "meat for sex hypothesis" had already been proposed to explain why male chimps might share with females.

    But previous attempts to record the phenomenon failed, because researchers looked for direct exchanges, where a male shared meat with a fertile female and copulated with her right away.

    Dr Gomes' team took a new approach. In a previous study, she had found that grooming exchange - where the animals take it in turns to groom each other - happens over long periods, she related. "So we thought, why not meat and sex?

    "We looked at chimps when they were not in oestrus, this means they don't have sexual swellings and aren't copulating."

    "The males still share with them - they might share meat with a female one day, and only copulate with her a day or two later."

    Dr Gomes thinks that her findings could even provide clues about human evolution.

    She suggests this study could lay the foundations for human studies exploring the link between "good hunting skills and reproductive success".

    "This has got me really interested in humans," she said. "I'm thinking of moving on to working with hunter-gatherers."

    Michael Gurven from the University of California in Santa Barbara studies human behaviour in communities of hunter-gatherers in South America.

    He told BBC News that the direct link between success in hunting and reproduction highlighted by this study could "help in our thinking about humans".

    Professor Gurven, who was not involved in this study, added that the nature of this exchange of meat for sex is "kind of like pair bonding in humans, because it's long-term.

    "This highlights something we haven't seen in chimps before."

    [h=1]Chimpanzee Hunting Behavior and Human Evolution[/h]Chimpanzees are efficient predators that use meat as a political and reproductive tool. Are there implications for the evolution of human behavior?
    Craig Stanford


    .....In the past five years I have been mindful of such questions as I observed the chimpanzees and their primary prey at Gombe, the red colobus monkey. Although we are only beginning to understand some of the causes and consequences of the chimpanzees' actions, what we have discovered is more complicated and more interesting than anyone suspected. For chimpanzees, meat is not only another way to get nutrients like fat and protein, but a means to make political bonds and gain access to sexually receptive females......
