On the origins of human emotions

the long version

"Language and culture are often seen as unique characteristics of human beings. In this book the author argues that our ability to use a wide array of emotions evolved long before spoken language and, in fact, constituted a preadaptation for the speech and culture that developed among later hominids. Long before humans could speak with words, they communicated their emotional dispositions through body language; and it is the neurological wiring of the brain for these emotional languages that represented the key evolutionary breakthrough for our species."--BOOK JACKET.
