Homologous structures are structures with similar physical features. The forelimbs of mammals are homologous organs to different animal structures.
What is homology?
Homology is the structure of the organ that originated from a common ancestor and has a similar structure. On the other hand, the analogous structure has a different structural framework.
The human arm, the flipper of whales, wings of bats, and birds have a similar structure and share a common ancestor.
Similarly, the forelimbs of humans, whales, and other mammals have evolved with the same structure.
Therefore, homologous organs have similar structures and common ancestors.
