First, it depends where the ancestors lived on the planet. Humans living in northerly, cold climates had no choice but to eat diets composed mostly of meat. In the past, it was theorized that humans ate mostly meat and some in-season fruit, root and greens that were raw. However, now scientists are changing their thinking about what our human ancestors ate 10.000+ years ago.
Recently, scientists found evidence that plants were cooked over 10,000 years ago.
Why does this matter? Think about all of the plants that are only edible after cooking. Also, cooking creates more nutrient-dense food, which has been proposed to have increased human brain size.
Paleo and primal diets have stressed the importance of foods that ancient (very ancient) ancestors used to eat. Primarily focusing on high-quality meat, fish and game, and some plant. In the light of this new research, it’s very probable and possible that our ancient ancestors ate more plants than we previously gave our ancient Caveman and lady credit for.
Scientists recently found evidence of ceramic pots and cooked plants inside of the vessels. Our caveman ancestors could have been boiling plants and processing different plants for a larger diet range.
Dr Julie Dunne, lead author of the paper and post-doctoral researcher, said: “Until now, the importance of plants in prehistoric diets has been under-recognised but this work clearly demonstrates the importance of plants as a reliable dietary resource.
“These findings also emphasis the sophistication of these early hunter-gatherers in their utilisation of a broad range of plant types, and the ability to boil them for long periods of time in newly invented ceramic vessels would have significantly increased the range of plants prehistoric people could eat.”
