Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. All of the animals in the figure, except for fish, lose their gill slits by adulthood.

Embryology supports the theory that organisms have a common ancestor (in ance 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.

Embryological support for evolution was proposed by Ernst Heckel based upon the observation of certain features during embryonic stage common to all vertebrates that are absent in adult.

Embryology, the study of the anatomy of an organism's development to its adult form, also provides evidence of relatedness between now widely divergent groups of organisms. Mutational tweaking in the embryo can have such magnified consequences in the adult that tends to conserve embryo formation.

Today, the major pieces of evidence for this theory can be broken down into the fossil record, embryology, comparative anatomy, and molecular biology.

Embryology is important to understanding a species' evolution, since some homologous structures can be seen only in embryo development. For example, all vertebrate embryos, from humans to chickens to fish, have a tail during early development, even if that tail does not appear in the fully developed organism.

Three types of evidence support evolution and natural selection: structural, microbiological, and direct observation. Structural evidence encompasses homologous structures and the fossil record. Microbiological evidence involves DNA similarities and shared processes across species.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species. Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide- resistant insects).
