Question

Which list shows the groups in order from most inclusive to least inclusive?

a. primates, hominins, hominids
b. primates, hominids, hominins
c. hominins, hominids, primates
d. hominids, hominins, primates

Answer 1

The correct order from most inclusive to least inclusive is:

b. primates, hominids, hominins

Here's why:
- **Primates** is the most inclusive group, which includes all primates, such as monkeys, apes, and humans.
- **Hominids** (also known as great apes) is a subgroup of primates that includes orangutans, gorillas, chimpanzees, and humans.
- **Hominins** is the least inclusive group and refers specifically to the lineage that leads to humans and their closest relatives after the split from the common ancestor with chimpanzees.

Thus, option b represents the correct hierarchy.
