Development homology
WebJun 24, 2012 · The preceding discussion has identified three developmental-causal definitions of homology: maximal, minimal, and consensus homology. These concepts are identical when each phene is associated with a single DC gene but, when there are multiple equivalent DC genes, a pair of traits judged homologous by one criterion might not be … WebDevelopmental Homology: In this type of homology, there is comparison between embryos of various species. Comparisons have shown similarities between species during their initial stages of life or early development. For example: Embryos of all Vertebrates are similar during the initial stages. Also, humans do not have tail or gills but these ...

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.

WebFeb 9, 2024 · Gillis and Tidswell use cell lineage tracing in embryos of the little skate (Leucoraja erinacea) to demonstrate the endodermal origin of gills. This finding supports the homology of cyclostome and gnathostome gills and overturns the hypothesis that gills evolved independently in these two ancient vertebrate lineages.
