The Naked Ape: A Zoologist's Study of the Human Animal by Morris, Desmond - 1968

London: Jonathan Cape, 1968. 7th Printing. Hard Cover. Very Good/No Jacket. Seventh printing. No jacket, boards very faintly toned. 1968 Hard Cover. 252 pp. The Naked Ape looks at humans as a species and compares them to other animals. The Naked Ape, which was serialised in the Daily Mirror newspaper and has been translated into 23 languages, depicts human behaviour as largely evolved to meet the challenges of prehistoric life as a hunter (see Nature versus nurture). The book was so named because out of 193 species of monkeys and apes, only humans (Homo sapiens sapiens) are not covered in hair. Desmond Morris, the author, who had been the curator of mammals at London Zoo, said his book was intended to popularise and demystify science.[1] Morris said that Homo sapiens not only have the largest brains of all higher primates, but that sexual selection in human evolution has caused humans to have the highest ratio of penis size to body mass. Morris conjectured that human ear-lobes developed as an additional erogenous zone to facilitate the extended sexuality necessary in the evolution of human monogamous pair bonding. Morris further stated that the more rounded shape of human female breasts means they are mainly a sexual signalling device rather than simply for providing milk for infants.[1] Morris framed many features of human behaviour in the context of evolution at a time when cultural explanations were more orthodox. For example, Morris wrote that the intense human pair bond evolved so that men who were out hunting could trust that their mates back home were not having sex with other men, and suggested the possibility that sparse body hair evolved because the "nakedness" helped intensify pair bonding by increasing tactile pleasure.[2] Like many other writers in the late 1960s and 1970s, Morris warned against the "population explosion" and overcrowding that might cause terminal damage to heretofore relatively stable social structures that humans had evolved in the long course of their development.
