Synopsis
A renowned scientist examines the less than two percent of human genes that distinguish us from chimpanzees and that link human behaviors--such as genocide, drug addiction, and the extermination of other species--to our animal predecessors
Reviews
Plenty of provocative ideas in this grand sweep of evolutionary biology and anthropology: not surprising for this MacArthur ``genius'' Award-winner, Natural History columnist, and UCLA Medical School physiology professor. With only 1.6 percent difference between the human genome and the genomes of two species of chimps, Diamond declares that we should call ourselves ``the third chimpanzee.'' (Curiously, he fails to mention neoteny as making a world of genetic difference.) Diamond first reviews human evolution, ending with the great leap forward that he attributes to language. New in this area is a discussion of animal art and communication (e.g., bowerbird constructions, vervet-monkey talk) and creolization (the development of sophisticated human languages from pidgin forms). With respect to other human features, Diamond reprises all the theories you've ever heard about sexual behavior, selection, menstruation, menopause, etc. Ditto for aging. He steers a common- sense course between extremes, opting for the games-theory approach of optimizing one's genes and of group survival. Old-but-not- fertile elders are essential imparters of knowledge for the group. A chapter on self-destructive behaviors (smoking, drinking, drug abuse) offers the peculiar theory that we do it to advertise that we are really superior because we can flaunt handicaps! No mention is made of the fit of the chemicals to receptors in the brain and to circuits evoking pleasure. Later, drawing on his special knowledge of New Guinea, Australia, and Polynesia, and his research on birds, Diamond provides a fascinating if overwhelmingly pessimistic view of human predation through genocide, species and resource destruction, and potential nuclear disaster. Conclusions of continued human, species, and planetary destruction are inescapable, in spite of Diamond's optimism that we can learn from the past and some modest success he has had with conservation programs. Quirky arguments at times, yes, but generally Diamond is as sharp as his name. (Twenty-five line drawings and halftones.) -- Copyright ©1992, Kirkus Associates, LP. All rights reserved.
Research biologist (Papua New Guinea, Solomon Islands) Diamond argues that the human being is just a third species of chimpanzee but nevertheless a unique animal essentially due to its capacity for innovation, which caused a great leap forward in hominoid evolution. After stressing the significance of spoken language, along with art and technology, Diamond focuses on the self-destructive propensities of our species to kill each other (genocide and drug abuse) and to destroy the environment (mass extinctions). He also discusses human sexuality, geographic variability, and ramifications of agriculture (metallurgy, cultivated plants, and domesticated animals). Absent from Diamond's work is the role religion plays in causing both war and the population explosion as well as long-range speculations on the future of our species. This informative, most fascinating, and very readable book is highly recommended for all libraries.
