Answer

Humans are more closely related to cats than to elephants.

Work Step by Step

The evolutionary tree indicates that elephants, cats, and humans shared a common ancestor that lived some 62 million years ago. Around this time, elephants diverged into their own species. At 61.5 million years, humans diverged from cats and the two became their own respective species. Species' that diverged more recently in history share more characteristics and are more closely related than species that separated earlier in history. As cats and humans diverged later than elephants and humans, humans are more closely related to cats.
