As concepções evolutivas de Darwin sobre a expressão das emoções no homem e nos animais

Abstract

Charles Darwin’s most known work is the Origin of species. However in such book, he did not deal with man. So he did in two other books: The descent of man and The expression of emotions in man and animals. This article aims to discuss some evolutionary conceptions present in these two works, as well as its background. This study led to the conclusion that although Darwin considered natural selection as being an important way of modification concerning the expression of emotions in man and animals, he stressed the role of the inheritance of acquired characteristics by use and disuse in relation to this subject
