Three types of homologous structures are morphological, ontogenetic and chromosomal. Morphology means shape, like the bones of whales and hummingbirds. Ontogenetics have embryonic similarities. Chromosomal means similar DNA.

Web23 jun. 2024 · Embryology supports the theory that organisms have a common ancestor (in accordance to theory of evolution). The theory of evolution explains that not every feature of an ancestor’s embryo is shown in its descendants. That explains why embryos develop into different species over time. Different traits are present in each embryo. WebDomains arising via convergent evolution can be called analogous rather than homologous structures.
