    Bonobo Mothers Supervise Their Sons' Monkey Business

    倭黑猩猩母親全權打理兒子的私生活

    Some parents get overly involved in their kids' personal lives. But bonobo mothers take this tendency to the extreme. They fix up their adult sons with a female of their choosing. And they even keep other males from getting near their future daughter-in-law. The behavior may seem overbearing, but it boosts the odds they'll be surrounded by grandkids. That's according to a study in the journal Current Biology.

    有些父母會過分干涉孩子的私生活,但是倭黑猩猩媽媽們把這種傾向發揮到了極致。她們會給成年的兒子安排她們選擇的雌倭黑猩猩,它們甚至親自出馬阻止其它雄性倭黑猩猩接近她們未來的兒媳。這種行為可能看起來很霸道,但卻增加了她們被孫輩包圍的可能性。這是根據《當代生物學》雜志上的一項研究得出的結論。

    Researchers studying wild bonobos in the Congo noticed that some females behaved a bit like males…fighting over fertile females and fending off some of the males who come a-courtin'. That observation struck primatologist Martin Surbeck as odd.“So I just wondered, hey what is it actually of their business, no? Most of the mammals it's just a male business, this competition over the access to females.”

    研究剛果野生倭黑猩猩的研究人員注意到,一些雌性倭黑猩猩表現的有點像雄性,她們會為爭奪有生育能力的雌性倭黑猩猩打架,還會擊退前來求愛的雄性倭黑猩猩。這一發現讓靈長類動物學家馬丁·蘇貝克(Martin Surbeck)驚訝不已。“所以我只是奇怪,嘿,這到底和她們雌性有什么關系,不是嗎?對于大多數哺乳動物來說,這種爭奪雌性的斗爭不都是雄性的事兒么。”

    To get to the bottom of this unusual activity, Surbeck, who is currently at the Max Planck Institute for Evolutionary Anthropology, got DNA samples from the players in this melodrama. “And so it became more apparent when we did the paternity analysis and it turned out these females were mothers of some males. And in this female dominated society of bonobos the mother acts kind of like a social passport allowing their sons to be more central in the group and therefore having more opportunities to interact with other females.”

    為了弄清這種不同尋常的行為背后的真相,目前在馬克斯普朗克進化人類學研究所任職的蘇貝克從這出鬧劇的主角身上提取了DNA樣本。“當我們作親子鑒定分析時,事情逐漸變得明朗,結果發現這些雌性倭黑猩猩其實是某些雄性倭黑猩猩的母親。在這個由女性為主導的倭黑猩猩群體中,母親的行為就像一張讓她們的兒子在群體中處于更重要位置的“社交護照”,因而(其兒子)也就有更多與其他雌性互動的機會。”

    And after the moms introduce their sons to the most desirable ladies, they make sure the couple won't be interrupted. As a result:“We found that males have about 3 times higher likelihood to sire offspring while their mom was still alive in the community.”

    當媽媽們把將她們的兒子介紹給最搶手的雌性之后,她們要確保這對夫婦不會被打擾。因而:“我們發現,(與其它母親不在世的雄性相比),當雄倭黑猩猩的母親在世時,其繁衍后代的可能性大了三倍。”

    In contrast, mothers of the closely related chimpanzees don't chaperone their sons. In fact, male chimps are less likely to sire offspring when their moms are around. Seems that chimps prefer privacy for their monkey business.

    與此相反,其近親黑猩猩的母親不會陪護兒子。事實上,當黑猩猩的母親在身邊時,身為兒子的雄性黑猩猩是不太可能繁殖后代的??磥?,黑猩猩在“敦倫”時似乎更注重隱私。
