The forelimbs of humans, cats, whales, and bats are similar in structure due to having a common ancestor hundreds of millions of years ago. Is this considered homolgy or analogy?

Scientists have found that the elephant shrew and the elephant share more DNA sequences than does the elephant shrew with a rodent. This evidence for evolution suggests to scientists that the elephant shrew and elephant

• are the same organism.

• may share a common ancestor

• have different ancestors

• are the same organism.
