this is because they have a link with early ancestors of similar structure.
Embryology is used in evolution because its shows a common ansetor. For example, a human and fi sh have similar embryos. Both embryos have pharyngeal slits. In a fish those develop into gills. In humans those turn into our ears.
Embryological development in animals displays the same set of nested hierarchies that is known from comparative morphology and genetics, and thus evidence for common descent.Nota bene: this adherence to nested hierarchies is not to be confused with the 19th century hypothesis of ontogeny recapitulating phylogeny. Embryos do not go through evolutionary stages during their development, but they dodisplay atavistic developments that are consistent with phylogenies based on other sources.
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
It does hint at common ancestry so it is "evidence" of evolution.
how does adaptations give evidence for evolution?
Related species have similar embryos.
All vertebrate embryos look roughly the same, showing that they come from a common ancestor.

Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.

Evolution
In evolution the study of vertebrate forelimbs is related to the anatomical evidence from homology.
