Apes Open Access Journals

 Apes are our closest wild relatives, but we push them to the brink. Today, they are among the most endangered groups anywhere. WCS continues to help lead the struggle to save them. Humans are primates, but the most similar primates are apes. We are therefore classified together with all the other apes in the primate sub-group known as hominoids (Superfamily Hominoidea). Apes are branches of the Old World tailed simian originating from Africa and Southeast Asia. They are a group of Old World ape brothers, together forming a catarrhine clade. Apes are distinguished from monkeys by the absence of tails and the presence of appendicitis and by their more complex brains. Although humans are zoologically categorized as members of the wider superfamily of apes, they are usually placed in their own subcategories due to their larger brain size, more advanced cognitive abilities (especially the ability to speak), and two-foot walking steps.
