Final answer:
An example of evidence from comparative embryology that supports biological evolution is the presence of similar development patterns in different species, indicative of common ancestry and homologous structures.
Step-by-step explanation:
Comparative Embryology and Biological Evolution
An example of evidence from comparative embryology that supports biological evolution is different species with similar development patterns. This includes observations of the development stages of embryos, where species that are closely related share homologous structures in their embryonic form. These structures may differ in the adult forms but their presence during embryonic development suggests a common ancestry. On the other hand, structures that serve similar functions but do not come from common ancestry are known as analogous structures, related more to convergent evolution than to phylogenetic connections.
For instance, the way bones are arranged in the limbs of various animals such as humans, dogs, birds, and whales is a result of these species evolving from a common ancestor. Even though the specific shapes and functions of these limbs have diverged, the similar embryonic origin is a powerful clue toward common descent and an example of homologous structures.
