Early horses were about the size of a fox. Vestigal structures like tail bones and homologous structures like hand, wrist, and forarm bones allow students to visualize common ancestry. These are seen in organisms

Fossils Provide Clear Evidence That Evolution Has Occurred.

Homologous structures that are greatly reduced in size or have little to no function are called vestigial structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. Comparisons of homologous structures across species, such as fins and flippers, provide evidence that.
