Eating Meat Helped Early Humans Reproduce, Population Spread
If early humans had been vegans we might all still be living in caves, Swedish researchers suggested in an article recently published in the journal PLoS ONE.
When a mother eats meat, her breast-fed child's brain grows faster and she is able to wean the child at an earlier age, allowing her to have more children faster, the study concludes. That provided a distinct competitive advantage for early humans when limited resources and a small population made it difficult for them to thrive.
