Developmental System Drift, lineages even as the trait itself remains conserved. Evidence for DSD comes from both interspecies hybridizations and comparative developmental genetic studies. The widespread occurrence of DSD implies that developmental systems are constantly evolving, even in the absence of selection for morpholo有斑点 发表于 2025-3-25 06:31:48

His studies on the lancelet, tunicates, insects, and germ layer homologies pioneered comparative embryology and confirmed the evolutionary continuity between invertebrates and vertebrates.

A number of hypotheses have been proposed to explain the evolutionary stability of different types of life cycle, and in some cases these hy陶器 发表于 2025-3-26 02:33:18

https://doi.org/10.1007/978-981-10-0216-8 key concept for evolutionary developmental biology because it is one of the properties of developmental systems that modulates the expression of phenotypic variation, influencing the potential for evolutionary change (i.e., evolvability). Although the relevance of canalization is widely accepted, m
