| Development of any animal requires the differentiation of different cell types and tissues from essentially the same initial cells. One of the first shared steps is the process of "gastrulation" (means gut formation). This forms the 3 cell layers that will form all the embryo, often described as "germ layers". | |||

Introduction
All human and animal embryos go through very similar stages of early development. See also Humans and Animal Embryology.
This page introduces a few of the concepts of comparative development shared with all animals.
