The forelimb of a whale and the wing of a bat are both used for locomotion, but in very different ways. however, when the bone structure of these limbs is examined, they are found to be very similar. this indicates that these two different species

Let's complete the question by adding the options

-have not adapted to the early environment

- are not related

- are members of the same species

- likely share a common ancestor

The ANSWER IS

- likely share a common ancestor

Explanation:

Computer analysis cevolutionan be used to trace evolution backward and scientists have used it reconstruct a large part of the genome of an 80-million-year-old mammal which is believed to be the common ancestor of humans and other living mammals as e.g. bats and whales.

Although, bats and Wales are not closely related, convergent evolution -- when almost identical features or developments happen in different species-- best explain the senerio

The similarity in the structures of the limbs from these two species indicated that the two species are from common evolutionary origin using the homologous data of the limbs.

Explanation:

The similarity between limbs from different organisms used for close function or greatly different ways as given above, but with great similarity in their structure is termed homologous. It indicates that these two organisms originated from a common ancestor, but due to modification of the stucture to adapt to the immediate environment, these organisms were able to utilize the structure, limb for locomotion if different types of habitat.
