Final answer:
The term for the modification of a limb for walking to a wing for flying in today's species, originating from a common ancestor, is convergent evolution, not biological organization, therefore the answer is b) False.
Step-by-step explanation:
The modification of a limb that was used for walking in a preexisting ancestor to one that is used as a wing for a species today is not called biological organization. The correct term for this phenomenon is convergent evolution. This type of evolution occurs when different species independently evolve similar traits due to having to adapt to similar environments or ecological niches, even though they are not closely related. An example would be the adaptive characteristics seen in the wings of bats and birds. The term analogous structures is used to describe wings in both bats (mammals) and birds (vertebrates), which perform the same function and have a superficially similar form, but the embryonic origin of the two wings is completely different.
An important aspect of adaptation is that it leads to the survival and reproduction of an organism in its present environment and is called an adaptation. Hence, the correct answer to the student's question is b) False.
