explain how Homologous and analogous help in study of evolution of life
Answers
Analogies are the result of convergent evolution. Interestingly, though bird and bat wings are analogous as wings, as forelimbs they are homologous. Birds and bats did not inherit wings from a common ancestor with wings, but they did inherit forelimbs from a common ancestor with forelimbs.
Homologous organs: Homologous organs are organs that have a similar basic structure but perform different functions. Example forelimbs of a human and whale.
Analogous organs: Analogous organs are organs that perform a similar function but are structurally different. Example wing of a bird and wing of a bat.
The presence of homologous and analogous organs helps in evolutionary studies and tracing the ancestry of a fossil. The presence of homologous organs suggests that the organisms is closely related to that species and shares a common ancestry. By determining the homologous organs in fossils we can determine the possible ancestry of the present day organisms.
The presence of analogous organs in fossils helps us to understand that the two species live(d) in a common environmental condition and have evolved to live in the same environment.
Thus by determining the presence of homologous and analogous organs in the fossils we can trace the possible ancestory of the present day organisms as well as determine the environmental conditions that prevailed in primitive times.
