Hierarchical Evolutionary-Developmental Theory

This book introduces a new evolutionary model called Hierarchical Evolutionary-Developmental Theory or H-Evo-Devo Theory. This theory proposes that the organism s internal properties reflect entities that are highly integrated in developmental terms that evolve hierarchically. In other words, it attempts to demonstrate that developmental constraints operate at different scales, producing distinct states of morphological stability reflected as subspecies, species, higher taxa, and homolo ...
