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.
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.

Embryology
Embryology shows the same thing that all other branches of biology and palaeontology show: a strong convergence of phylogenies based on independent assays of traits, both morphological traits at the various stages of development as well as the developmental paths taken by the various organisms. This can only be explained by common descent.
The basic textbook answer is: embryology, homologous and analogous structures, and fossils. However these are old ideas and don't stand on their own two feet, so to speak, when more research is done into them.

embryology has an important role in the animals as it tell us the ontogenic development of an organism.it helps us to understand how an embryo undergoes different changes to reach the adult stage...i.e its growth,cell division and cell differentiation can be well studied in embryology.
