Question

Distinguish which structures are similar in form and function between these three species. Explain the importance of these similarities as they relate to an understanding of common ancestry.

Answer 1

Homologous structures in biology help us understand common ancestry between species.

Step-by-step explanation:

In biology, scientists use homologous structures to understand common ancestry between species. Homologous structures are similar in form and function and suggest a shared evolutionary history. For example, the limbs of mammals such as bats, lions, whales, and humans are homologous structures that have a common ancestor and can be used to trace their evolutionary relationships.

By studying the similarities in structures such as bones, organs, or body parts, scientists can infer that these species share a common ancestor. This understanding of common ancestry is important because it helps scientists reconstruct the evolutionary history of different species and understand the relationships between them. It provides evidence for the theory of evolution and helps us understand how different species have diversified over time.
