Paul Pettitt in Sapiens:
The recent study’s analysis of zinc from the tooth enamel of a Neanderthal who lived and died around 150,000 years ago in the Spanish Pyrenees gives new insights into the diet of ancient humans. Zinc isotopes were analyzed from 43 teeth of 12 animal species living in a grassland around the Los Moros I Cave in Catalonia, Spain. These included carnivores such as wolf, hyena, and dhole (also known as mountain wolf); omnivorous cave bears; and herbivores including ibex, red deer, horse, and rabbit. The results brought to life a food web of the Pleistocene steppe, a system of interlocking food chains from plants up to the top carnivores. The zinc in the Neanderthal’s tooth had by far the lowest zinc value in the food web, revealing they were a top-level carnivore.
