Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Montrevious is curious if bats, butterflies, or flying squirrels all have the ability to fly, sharing the same function. However, their structures are are different, indicating a different origin. What is this called?
A
Fossil structure
B
Anatomical
C
Analogous Structure
D
Homologous Structure
Explanation: 

Detailed explanation-1: -No, wing of bat and wings of butterfly should not be considered as homologous organs because they have different structure and origin but have the same function of flying so they are analogous organs. Was this answer helpful?

Detailed explanation-2: -Bird and bat wings are analogous-that is, they have separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them to play a key role in flight.

Detailed explanation-3: -Butterfly and bird wings, on the other hand, are analogous and do not meet any of the criteria. Analogous structures may look similar on the surface, but since their similarity is due to convergence rather than common ancestry, analogous structures generally don’t meet all of the criteria above.

Detailed explanation-4: -Wings of butterflies and wings of birds exhibit homology. III. Organs with dissimilar structures, performing similar functions are called analogous organs.
