Comparative embryology supports the theory of evolution because scientists have found that the embryos of many different species show similarities, which implies they share a common origin. For example, in humans the emb... More »

The phylogenetic species concept defines a species as a group of organisms that shares a common ancestor and can be distinguished from other organisms that do not share that ancestor. As an analogy, the phylogenetic spec... More »

The muscular systems of humans and frogs share a number of anatomic and biochemical similarities, including the same basic muscle groups, a similar muscle fiber structure and the presence of acetylcholine-based neuromusc... More »
