Paperback. Etat : New. Print on Demand. This book delves into the inheritance of coat colors and coat patterns in rats and guinea pigs, analyzing the role of variation and heredity in the development of these traits. The author challenges the prevailing view that evolution is solely driven by the accumulation of small, continuous variations, instead arguing that discontinuous variations, or mutations, can also play a significant role. Through meticulous experiments involving selective breeding and cross-breeding, the author demonstrates the malleability of discontinuous variations, challenging the notion that they are not subject to evolutionary change. The book thus expands our understanding of the mechanisms underlying evolution, suggesting that both continuous and discontinuous variations contribute to the formation of new species. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
