Explain with suitable example important of anatomical evidence in evolution
Answers
Another type of evidence for evolution is the presence of structures in organisms that share the same basic form. For example, the bones in the appendages of a human, dog, bird, and whale all share the same overall construction
Answer:
Anatomical evidences help us to study how species have evolved over a period of time. Analogous structures support the theory of evolution and explain the fact that how species build up adaptations in order to fit in an environment whereas homologous structures help us to understand common ancestry. For example, if we compare the hands of humans with cat’s foreleg, flipper of whale and patagium of bat, we see that each of these organism use these structures are differently. But still there is a similarity between the structure of bones and joints which indicates that somewhere or the other these animals may have originated from common ancestors. This is an example of homology. Another example which explains analogous features is the arctic fox and the ptarmigan bird, Both of them change colours from dark brown to white during seasonal changes. They do not show common ancestry in way but since, they are found in the same habitat they are adapted to colour change.
