In early stages, what body parts do humans have in common with reptiles, mammals, and birds?
Homework Answers
Embryos of human and other animals like reptiles, mammals and birds often look alike at certain developmental stage .Because they all share common ancient genes. These ancient genes express at phylotypic period of embryonic development in all the embryos. During this period all the embryos develop tail as well as gills slits. Adult human retain the coccyx while others develop proper tail. In humans, gill slits form the lower jaw and eustachian tube. Gill slits persist only in fish and larval amphibian.

Exercise: Many older classifications are not monophyletic, and do not reflect the evolutionary relationships among species. As an introduction to phylogenetic classification, think about the tetrapods (animals with four legs). These animals have traditionally been classified into four groups, all of the same rank: Class Amphibia (frogs, salamanders, newts, etc.) Class Reptilia (snakes, lizards, crocodiles, turtles, etc.) Class Aves (birds) Class Mammalia (mammals) Reptiles possess a common ancestor with certain extinct amphibians, the birds are derived from a group of...
