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. Web16 jun. 2024 · In divergent evolution, homologous structures are structures indicating a species is diverging from its ancestor. ... Their similarity in this regard could indicate plausible evolution from a common ancestor.
