Chimpanzee

　　The most striking single fact about chimpanzees is the flexibilityof their social life, the lack of any rigid form of organization. It representsabout as far a departure from the baboon type of organization  as one canfind among the higher primates, and serves to  emphasize the  great variety of primate adaptations. Chimpanzees are morehuman than baboons, or rather they jibe better with  the way we liketo  picture  ourselves, as free-wheeling individuals whotend  to  be unpredictable, do not take  readily to any form ofregimentation,  and  are frequently  charming.(Charm isrelatively rare among baboons.) Two researchers have described what they foundduring more than eight months spent among chimpanzees in their naturalhabitat the forest:"We were quite surprised to observe that there is nosingle distinct social unit in chimpanzee society. Not only is there no'family' or 'harem' organization; neither is there a 'troop'  organization - that is to say, no  particular chimpanzees keep permanently together. On the  contrary, individuals move about atwill, alone or in small groups best described as bands, which sometimes forminto large aggregations.
　　They leave their associates if they want to, and joinup with new ones without conflict. " The general  practice is   best   described  as  "easy come,  easy   go",   although  there are  certain group-forming tendencies. As a rule chimpanzees moveabout in one of four types of band: adult males only; mothers andoffspring and occasionally a few other 
females; adults and adolescents of both sexes, but no mothers with youngand representatives of all categories mixed together. The composition  of  bands  may  change  a number  of  times  during  the   course  of  a  day as individuals wander off and groups split orcombine with other groups. On the other hand, certain individuals prefer oneanother's company. One of the researchers observed that four males oftenroamed  together    over  a four-month period,  and  mothers  often  associated  with their  older offsprings.

　　黑猩猩最突出的一個特征是它們社會生活的靈活性，即缺乏固定的組織形式。它的這一特征與狒狒的那種組織形態間的差別，在靈長動物中最為突出。由此可見靈長類動物中 適應性變化的多樣性。黑猩猩比狒狒更接近人類，或者說它與我們心愿的自我形象更為接近：自由自在，不落窠臼，不喜歡任何形式的約束并且往往魅力十足(在狒狒中魅力比較罕 見)。通過在黑猩猩的自然棲息地森林中對它們進行了8月的觀察，兩名研究人員得出這樣結論："我們注意到在黑猩猩的社會中似乎沒有任何一種獨立的社會基本單位，這一點令我們很吃驚。  
　　它們不僅沒有'家庭'或'妻妾'組織，也沒有'團隊'組織，也就是說黑猩猩沒有固 定地生活在一起。相反，每只黑猩猩隨意流動，或是獨自一人，或是作為最好稱之為團伙的一員。 團伙有時會與其它團伙合并成大的聚合體。它們可以隨意離開同伴，并與其它黑猩猩組成新的團伙而不會產生任何糾紛。"把黑猩猩這一總的特性稱之為"來得容易去得快" 是最恰當不過了。但它們也有一定的群體傾向性。通常，黑猩猩群的構成有以下4種：僅有成年雄性；母猩猩及其子女而且偶爾有幾只其它的雌性猩猩；雄性和雌性的成年和未成 年黑猩猩但不包括有子女的雌性黑猩猩； 以及各種類型混雜在一起。一天之中一個團伙的組成可能變化好幾次，因為有的成員可能離開，而且群體可能會與其它群體合并。另一方 面，有些黑猩猩有自己喜歡的伙伴。一名研究人員發現四只雄性黑猩猩在4個月中常常共 同游蕩，還有母親們常與她們較年長的子女們在一起。
