WebEmbryonic homologies. One of the most important distinctions made by the evolutionary embryologists was the difference between analogy and homology. Both terms refer to structures that appear to be similar. Homologous structures are those organs whose underlying similarity arises from their being derived from a common ancestral structure. … WebDevelopmental Homology. In developmental homology, similarities can be observed in particular developmental stages of the organisms. For example, all vertebrate embryos (even humans!) have gill slits and tails that disappear by the time of birth. We can infer that all vertebrates can be linked to a common ancestor. Figure 5.
WebMar 8, 2024 · Developmental system drift (DSD) is defined (True and Haag 2001) as the process by which conserved traits diverge in their developmental genetic underpinnings over evolutionary time. This concept was independently articulated by Weiss and Fullerton ( 2000) as “phenogenetic drift. ” Motivated by modern developmental genetics research ...
