Species and Varieties: Their Origin by Mutation is a scientific book written by Hugo de Vries, a Dutch botanist and geneticist. This book is a comprehensive study of the concept of mutation and its role in the evolution of species and varieties. De Vries argues that mutation is the primary mechanism of evolution, and that natural selection plays a secondary role. He provides a detailed analysis of the different types of mutations, their causes, and their effects on organisms. The book also includes case studies and experiments that support de Vries' theory. It is an important work in the field of genetics and evolutionary biology, and has influenced many subsequent studies in the field.From time to time the idea has suggested itself to some of the best authorities on the amelioration of plants, that this atavism was not due to an innate tendency, but, in many cases at least, was produced by crosses between neighboring varieties. It is especially owing to Verlot that this side of the question was brought forward. But breeders as a rule have not attached much importance to this supposition, chiefly because of the great practical difficulties attending any attempt to guard the species of the larger cultures against intermixture with other varieties. Bees and humble-bees fly from bud to bud, and carry the pollen from one sort to another, and separation by great distances would be required to avoid this source of impurity.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions, that are true to their original work.
