Homo antecessor is an early hominin that lived in Europe between 1.2 million and 600,000 years ago. Homo antecessor was similar in height to modern humans and was fully bipedal. But Homo antecessor fragments diverged in one respect: a relatively thinner outer table and thicker inner table than in either of those two groups. According to the scientists, the results reinforce the ‘mosaic’ picture of Homo antecessor first proposed when the species was named from Gran Dolina fossils.
