Final answer:
Lemurs, tarsiers, and monkeys are primates that have not evolved into humans. Humans evolved from a common ancestor with chimpanzees approximately six million years ago.
Step-by-step explanation:
Primates that have not evolved into humans include lemurs, tarsiers, and monkeys. These primates have distinct characteristics that differentiate them from humans, such as their smaller size, different locomotion patterns, and specific adaptations for their habitats.
Humans evolved from a hominid ancestor that is believed to be a common ancestor with chimpanzees. The fossil record and DNA evidence suggest that humans and chimpanzees diverged from this common ancestor approximately six million years ago. Several species evolved from this evolutionary branch, but modern humans (Homo sapiens) are the only surviving member.
