Skeletons show that early farmers were shorter and sicker than the foragers who preceded them. Yet farming populations grew rapidly and steadily displaced forager populations across every region where the two met.
Which of the following best explains why the less healthy farmers nonetheless grew and displaced foragers?
- Foragers occasionally adopted some farming techniques.
- Farming yielded far more food per acre, letting women bear and raise more surviving children despite poorer individual health.
- Early farmers built more permanent dwellings than foragers.
- Forager skeletons are harder to find than farmer skeletons.
- Farming spread fastest in regions with fertile soil.
