Stone Age people obtained their essential proteins from a variety of sources, including plants, nuts, seeds, and insects.

It is difficult to determine an exact daily protein requirement for Stone Age people, but 50-60g daily may have been sufficient for their needs, especially considering the variety of protein sources available to them. **
