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: -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-3: -Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related.

Detailed explanation-4: -Comparative embryology is the comparison of embryo development across species. All embryos pass from single cells to multi-celled zygotes, clumps of cells called morulas, and hollow balls of cells called blastulas, before they differentiate, creating the organs and systems of the body.

Detailed explanation-5: -Comparative embryology shows the similarities in embryonic development between species indicating we all came from one common ancestor that evolved into different species over millions of years.
