The incorporation of meat into the diet was a milestone for the human evolutionary lineage, a potential catalyst for advances such as increased brain size. But scientists have struggled to determine when meat consumption began and who did it. New research provides the first direct evidence that Australopithecus, an important early human ancestor that displayed a mix of ape-like and human-like traits, consumed very little or no meat, relying on a plant-based diet. The study determined the diet of seven Australopithecus individuals from South Africa dating to between 3.7- and 3.3-million years ago based on the chemistry of their tooth enamel. “Meat likely played a significant role in the expansion of cranial capacity — larger brain development — during human evolution. Animal resources provide a highly concentrated source of calories

A newly analyzed DNA sequence from a Neanderthal specimen, nicknamed “Thorin,” reveals an isolated lineage that persisted for 50,000 years, according to a study published in the journal Cell Genomics. Thorin, discovered in 2015 at the Grotte Mandrin rock shelter in the Rhône River valley of southern France, is believed to have lived as recently […]
