Homologous organs area)Dissimilar origin and dissimilar structuresb)Dissimilar origin but similar functionsc) Similar origin with similar or dissimilar functionsd) Similar origin with dissimilar functionsCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Homologous organs represent common ancestry, we can say that homologus organs are result of divergent evolution, in which a organ which have same origin modified to perform different functions or similar functions according to the habitat.
for example,1. Whales ,bats , cheetah and human or we can say all mammals share similarities in the pattern of bones of forelimbs the function of these forelimbs in different animals is different.
vertebrates heart is also example of homology ..
2. potato and Ginger both are stem modification and they perform the function of storing food they are homologous organs and perform the same function.
so,by above example u can see best answer is 3rd.

Answer

Check the answer because, I think D is the correct option. Since, Homologous organs are defined as the organs of different animals that are having a similar structure but differ in their functions.

Answer

Similar Origin with Similar or Dissimilar Functions

Homologous organs are organs that have a similar origin, meaning they are derived from a common ancestral structure. These organs may have evolved to have similar functions, or they may have different functions despite their shared origin. The correct answer to the question is option 'C', which states that homologous organs have a similar origin with similar or dissimilar functions.

Similar Origin:
Homologous organs share a common developmental origin. This means that they are derived from the same embryonic tissues or structures. For example, the forelimbs of vertebrates, such as the arms of humans, the wings of birds, and the flippers of whales, all have a similar origin as they develop from the same embryonic limb buds.

Similar or Dissimilar Functions:
Homologous organs can have either similar or dissimilar functions, despite their shared origin. This is because during the process of evolution, these organs may have undergone modifications to adapt to different environmental conditions or perform different tasks.

Similar Functions:
In some cases, homologous organs may have evolved to have similar functions. This is known as convergent evolution, where different species independently evolve similar traits to adapt to similar environments. For example, the wings of birds and the wings of bats have a similar function of flight, even though their structures are different.

Dissimilar Functions:
On the other hand, homologous organs can also have different functions. This is known as divergent evolution, where ancestral structures diverge and adapt to perform different tasks. For example, the forelimbs of humans are adapted for grasping and manipulating objects, while the forelimbs of whales are adapted for swimming and steering.

Conclusion:
Homologous organs have a similar origin, but their functions can be either similar or dissimilar. This is because during the course of evolution, these organs may have adapted to different tasks or environments. Understanding the concept of homologous organs is important in the study of comparative anatomy and evolutionary biology.
