Even though the limbs are used for different purposes, all the organisms show a similar arrangement What does this evidence tell us regarding common ancestory ? Explain

It tells us that homologous structure is evidence of common ancestry

Explanation:

Homology is the similarity of organs of different organisms even though they perform different functions in the organisms. Organs that are built on a similar plan but perform different functions are known as homologous organs.

Organisms having organs built on a similar plan is an indication that they were once from the same source and adapting to different environments must have been the reason the organs evolved for different functions.

For example, all mammals have limbs that are built on a similar five-digit plan even though limbs are adapted for different functions in different mammals.
