Print on Demand. This book argues that evolutionary change takes place not through sudden, large-scale mutations, as put forward by the mutation theory, but rather through a slow accumulation of small, gradual variations. The author contends that mutations are often very small, unstable, and difficult to distinguish from ordinary variation. Drawing evidence from genetics, paleontology, and breeding experiments, the author challenges the idea that species can be sharply categorized and instead suggests that they exist on a continuum of variation. By questioning the validity of the mutation theory and offering an alternative perspective on the mechanisms of evolution, this book provides valuable insights into the nature of species and the processes that shape their diversity. 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.…

- Evolutionary Biology
This extract surveys key questions in heredity and variation, showing how researchers test ideas about Mendelian inheritance, mutation, and the role of selection. It weighs evidence from experiments, debates about stability and discontinuity, and the limits of crossing tests, all while tracing how views have shifted over time.
- Learn how researchers distinguish stable variation from transient fluctuation
- See real examples, from plant crosses to animal hybrids, that test ideas about inheritance
- Understand critiques of unit characters, determinants, and other particulate theories
- Follow the argument for a view of evolution shaped by selective processes and gradual change
Ideal for readers of biology, history of science, and anyone curious about how scientific theories evolve through evidence and argument.
