Actually yes it can. Embryos, DNA sequences, and fossils amongst others things can help show similarities within species. This can show that those species have similar traits because they evolved from a common ancestor. But those differences show why they are different species and thus evolving.
Ontogeny recapitulates phylogeny, or the development of the individual summarizes the evolution of the species. For example, human embryos go through a stage in which they develop gills as did their aquatic forerunners.
this is because they have a link with early ancestors of similar structure.
The morphology of embryos at various stages, and even the developmental patterns of embryos, show the same pattern of nested hierarchies that we find in morphology, behaviour and genomes, independently confirming common descent, but also teaching us how morphologies could diverge through relatively minor genetic shuffling.
The stages of development of the embryos of certain organisms are extremely similar, a fact that suggests the organisms had common ancestors.
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.

All vertebrate embryos look roughly the same, showing that they come from a common ancestor.
Basically, its the shape of the embryos of vertebrates. If the shape of the embryos are similar, that means they evolved from a common ancestor.More specifically, it's the pattern of nested hierarchies that is found when one compares the embryological developmentof species. Also, developmental atavisms, such as the branchial arches in human embryos, are important clues telling us about our ancestry.
Related species have similar embryos.

Fruit Flies and frog eggs are long-time,well characterized standbys in the lab environment,and specific manipulations allow researches to introduce genes from other organisms into these species
evolution from a distant common ancestor
