In this book I attempt to find a solution of some of the most difficult of the problems of evolution. First I try to show that Lamarck's explanation of evolution will not bear investigation. But if the dovetailing of species into their environment has not been brought about, as he maintained that it had, by the moulding influence of the environment itself and the development of the organism by exercise, how have adaptations been effected? To account for them, the Neo-D arwinian, the follower of Weismann, has at his service only variations - he assumes that a tendency to vary pervades the whole organic world - and, as a regulating principle. Natural Selection. Nothing further, as I hope to make clear, is wanted to account for all the niceties of adaptation. Moreover, evolution appears to follow certain lines, and species group themselves in orderly series. This becomes intelligible, if we realise that all species, even the lowest, to a certain extent, pilot themselves. In other words, heredity limits the range of variation, and limits it more narrowly as evolution advances. Sexual selection and isolation present problems, which though perhaps of less importance, are of the utmost interest. The second part of the book deals with human evolution.

Paperback. Etat : New. Print on Demand. This book tackles questions of evolution, a topic that has fascinated scientists for centuries. While grounded in the well-respected Darwinian theory of natural selection, the author goes further, introducing the ideas of other influential thinkers such as Lamarck. The book explores the concepts of heredity, variation, and death, and questions whether acquired characteristics can be passed on genetically. The author examines the mechanisms of evolution, such as natural selection and sexual selection, and discusses the role of isolation in the formation of new species. This book is essential reading for anyone interested in evolution and the history of life on Earth.
