Do the similarities suggest these animals share a common ancestor? Explain.

Yes, the similarities between these animals suggest that they share a common ancestor. This is because common ancestry would explain why these animals have similar physical traits or behaviors. Over time, as a common ancestor evolved, its descendants also shared similar genetic information that led to the development of similar characteristics. This concept is often referred to as homology, where similarities between different species are the result of shared ancestry. So, the similarities between these animals can be seen as evidence of their shared evolutionary history.
