Ancient ancestors dug potatoes!

A new study using human bone isotope chemistry to model the diets of early Holocene-era humans in the Andean highlands in Peru has found that plant foods made up 70 to 95 per cent of these foragers’ diet, with tubers like potatoes probably dominating. The authors say “The current study arrives at a similar place to the earlier ethnographic findings – plant foods were central to early human economies.”
This finding adds to a growing body of evidence suggesting early human populations relied far more heavily on plant foods than previously thought – more gathering than hunting!
