Q: those are called homolgous structures because the skeletons are very similar and imply a common how do i answer 20pts

The skeletons may be similar but it usually focuses on one part. Meaning that the homologous structure would be a monkey paw, or the flipper of a whale.

They would be in the same classification. Such as humans are called homo sapien sapien. The family would be homo if I'm correct, meaning that if scientists are able to use the DNA of that structure to relate it to a common ancestor.

It would be true. Or if it's a multiple choice question, we need to know the choices.
