One of science's greatest intellects examines how people and animals display fear, anger, and pleasure. Darwin based this 1872 study on his personal observations, which anticipated later findings in neuroscience. Abounding in anecdotes and literary quotations, the book is illustrated with 21 figures and seven photographic plates. Its direct approach, accessible to professionals and amateurs alike, continues to inspire and inform modern research in psychology. AUTHOR: English naturalist and geologist Charles Darwin (1809 82) attended the University of Edinburgh as a medical student, later enrolling at Christ College, Cambridge, where he earned a degree in theology. During an expedition to Africa and South America, Darwin continued his studies in natural science and began writing about his theories of natural selection. His work led to the publication of On the Origin of Species, one of the world's most important and influential books and the keystone of evolutionary thought.
