The patterning of intraspecific variation among the great apes is proving more complex than has been recognized previously. The great ape species, as currently defined, may include markedly different subspecies, alternatively, the majority of intraspeclflc variation may be observed at the populational level within a single subspecies. Recent studies have raised a number of questions about great ape evolutionary biology. How many species of living great apes exist? What was the original dietary adaptation of gorillas? How should we define male orang-utan adulthood?
大猿种内变异模式比以前认识到的更为复杂。目前所定义的大猿物种可能包括明显不同的亚种，或者，大多数种内变异可能在单一亚种的种群水平上观察到。最近的研究对大猿进化生物学提出了一些问题。现存大猿有多少个物种？大猩猩最初的饮食适应是什么？我们应该如何定义雄性猩猩的成年期？
