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 a few basic farming techniques after watching neighboring farming groups at work nearby.
- Farming yielded far more food per acre, letting women bear and raise more surviving children despite poorer individual health.
- Early farmers built far more permanent and substantial year-round dwellings than the highly mobile foragers near them ever did.
- Forager skeletons are generally a great deal harder for working archaeologists to locate and to recover than farmer skeletons are.
- Farming tended to spread fastest across those particular regions that happened to be blessed with deep and fertile soil.
