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 ancistory of a fossil. The presence of homologous organs suggests that the organims is closely related to that species and shares a common ancestory. By determining the homologous organs in fossils we can determine the possible ancestory 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 enviormental 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.

The significance of studying homologous and analogus organs is as follows:
Explanation:
- The homologous organs can be defined as those organs which are found to be structurally similar in living organisms but they are functionally dissimilar. For example, the forelimbs of the whales and the humans.
- The homologous organs are significant because these are necessary for drawing phylogenetic and ancestral relationship between the living organisms. The structure may appear similar because they may have commonly originated from the ancestor.
- The analogous organs can be defined as those organs which are found to be structurally different but functionally similar. For example, wings of bat and bird.
- The analogous organs are significant because these tell that two organisms were exposed to the same environment conditions this resulted in adaptation of same kind of functional role of following similar ecological niches even through living in geographically distinct areas.
