Summary:
- The article discusses how early humans evolved the ability to digest starch, which was a crucial adaptation that allowed them to thrive on a more diverse diet and expand their geographic range.
- Researchers analyzed the genetic changes that enabled early humans to produce more amylase, an enzyme that breaks down starch, which gave them a significant advantage over other hominid species.
- This adaptation to starch-rich foods, such as tubers and roots, played a key role in the evolution and dispersal of early human populations, and it continues to shape human health and nutrition today.
