Genetics and the Origin of Species by Theodosius Dobzhansky

This book is a seminal work in the field of evolutionary biology that introduces the concept of genetics as a fundamental mechanism in the process of evolution and speciation. The author combines theoretical concepts and empirical data to argue that natural selection and genetic variability are the driving forces behind the evolution of species. He also discusses the role of geographic isolation in speciation and provides a comprehensive overview of the genetic basis of evolutionary change.
