Evolution 4th edition by Emlen

Evolution 4th edition by Emlen, published by Macmillan, presents evolutionary biology as a dynamic field grounded in evidence, mechanisms, and modern research. Designed for undergraduate biology courses, the text explains natural selection, genetic variation, adaptation, speciation, phylogenetics, sexual selection, and the evolutionary history of life. Students are guided through both classic studies and contemporary examples that show how evolutionary thinking applies to medicine, behavior, ecology, and conservation. With an emphasis on scientific reasoning and data interpretation, this edition helps learners understand how evolutionary processes generate biological diversity across genes, organisms, and populations.
