Biology (CHECK)

Describe how comparing the anatomy of living species provides evidence of evolution.

A: Comparisons of the anatomy of different types of organisms often reveal basic similarities in body structures even though the structure's functions may differ between organisms. For example, sometimes bones are present in an organism but are deducted in size and either have no use of have a less important function that they do in other, related organisms. Such structures, which are considered to be evidence of an organism's evolutionary past, are called vestigial structures.
