The pace of human physical development is slower than that of other primates, meaning that it takes us longer to move from childhood through adolescence to adulthood. Scientists have long believed that this is related somehow to the complex nature and large size of the human brain, which takes more time to mature in harmony with the human body. There are questions about how early the ancestors of modern humans ( Homo sapiens) started physically maturing at a delayed rate, in comparison to their primate cousins. In a new study just published in the journal Nature, a team of European scientists presents evidence that suggests delayed growth in the human evolutionary line first appeared in approximately two million BC, or
