我们报告了一个严重残疾的雌性婴儿黑猩猩（Pan troglodytes schweinfurthii）的身体和行为发育的良好习惯的M组在Mahale山脉国家公园。我们记录了婴儿与母亲以及其他小组成员之间的互动。先天性残疾发生在许多灵长类动物中，包括黑猩猩。然而，只有少数关于先天残疾的黑猩猩婴儿的案例研究，也没有关于黑猩猩母亲如何在野外处理这种残疾婴儿的报告。观察到的婴儿表现出类似唐氏综合症的症状，类似于以前报道的圈养黑猩猩。母亲不允许非亲属照顾婴儿，尽管她以前对非亲属的异母繁殖相对宽容。母亲对婴儿残疾的补偿性照顾和妹妹对婴儿的异母异父可能有助于婴儿在野外生存23个月。其他小组成员对残疾婴儿没有表现出任何厌恶或恐惧的反应。
We report the physical and behavioral development of one severely disabled female infant chimpanzee (Pan troglodytes schweinfurthii) of the well-habituated M group in the Mahale Mountains National Park. We documented interactions between the infant and its mother and with other group members. Congenital disabilities occur in many primate species, including chimpanzees. However, there have been only a few case studies of congenitally disabled chimpanzee infants and no reports examining how a chimpanzee mother copes with such a disabled infant in the wild. The observed infant exhibited symptoms resembling Down syndrome, similar to those reported previously for a captive chimpanzee. The mother did not allow nonrelatives to take care of the infant even though she had been previously relatively tolerant of allomothering by nonrelatives. The mother's compensatory care for her infant's disabilities and allomothering of the infant by its sister might have helped it to survive for 23 months in the wild. Other group members did not show any aversive or fearful reactions to the disabled infant.
