Observe the below pictures and identify the category of organs.
Homologous organs
Homologous structures are parts of the body that are similar in structure to other species' comparative parts. These similarities are evidence that life on Earth has a common ancient ancestor that the diverse species have evolved from over time. The common ancestry of the species can be seen in the structure and development of these homologous structures, even if their function is different.
The more closely the organisms are related, the more similar the homologous structures between organisms. Most examples of homologous structures revolve around the limbs of the species being compared. The bone structure within those limbs are similar between closely related species.
The bones in the forelimbs of Human, cat, whale and bat are similar though the functions are different.
