Homology, Genes, and Evolutionary Innovation

Günter P. Wagner


Homology—a similar trait shared by different species and derived from common ancestry, such as a seal's fin and a bird's wing—is one of the most fundamental yet challenging concepts in evolutionary biology. This book provides the first mechanistically based theory of what homology is and how it arises in evolution. The book argues that homology, or character identity, can be explained through the historical continuity of character identity networks—that is, the gene regulatory networks that enable differential gene expression. It shows how character identity is independent of the form and func ... More

Keywords: homology, common ancestry, evolutionary biology, character identity network, gene regulatory networks, gene expression, biological diversity, evolution, character identity
