A scientist examines the two animals shown below and concludes that they must have shared a common ansecstor at some point. Based on your understanding of homologous structures, determine whether his conclusion is valid. Explain your reasoning.

Homologous structure are structures that are similar in appearance but differs in their functions. Such organs are usually inherited from a common ancestor.

The forelimbs of bat and that of bird as shown in the image are homologous to each other. They are both similarly built but performs different functions. This means that they both inherited the forelimbs from a common ancestor.

Hence, the conclusion of the scientist is valid.
