ANATOMY

Detailed explanation-1: -Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails.

Detailed explanation-2: -Similar anatomy across different species highlights their common origin and can be seen in homologous and vestigial structures. Embryology provides evidence for evolution since the embryonic forms of divergent groups are extremely similar.

Detailed explanation-3: -The field of comparative embryology aims to understand how embryos develop, and to research the inter-relatedness of animals. It has bolstered evolutionary theory by demonstrating that all vertebrates develop similarly and have a putative common ancestor.

Detailed explanation-4: -Human Embryology and Developmental Biology is the study of the fascinating process in humans and animals that turns a single fertilised egg into a whole new individual with all the many specialised cell types.

Detailed explanation-5: -Many traits of one type of animal appear in the embryo of another type of animal. For example, fish embryos and human embryos both have gill slits. In fish they develop into gills, but in humans they disappear before birth.
