Beskrivelse
Originally published in 1914, this book contains a study of the causes that lead to the appearance of males and females in a number of species, including humans. Doncaster uses simple language to appeal to a non-specialist audience, and the text is illustrated with a number of plates illustrating the differences between the sexes in insects, birds and mammals. This book will be of value to anyone with an interest in the history of science.
