Question

Quizplus · Accepted Answer

The most accepted hypothesis is that the common ancestor of humans and chimpanzees lived about 6 million years ago. While they would have shared many characteristics, both species have evolved since then, meaning that their ancestor would not look identical to either present-day chimpanzees or humans. Therefore, option C is the correct answer. Option A is incorrect because chimpanzees have also undergone evolutionary changes since that time, and their ancestors would not look identical to present-day chimpanzees either. Option B is incorrect because early humans would not have been identical to present-day humans. Option D is also incorrect as the ancestors of chimpanzees would not have resembled present-day humans.
