These two volumes demonstrate the role of cellular mechanisms in the production of the many specialized traits defining primates. By exploring gene activity transforming into evolutionary change through the work of cellular mechanisms, the goal is to encourage others to adopt evolutionary cell biology as an approach to the genotype-phenotype map of the diversification of primates, human variation, and human evolution. Contributors highlight how genetic analysis, visualization of cells and tissues, and merging Evo-Devo with evolutionary cell biology combine to answer questions central to understanding the human and primate evolution. Key Features Explores the developmental basis of characteristics that define the primate lineage Documents cellular mechanisms associated with everything from skin and eneregetics to the brain and communication.
