Human newborns arrive remarkably underdeveloped. The reason lies in a deep evolutionary trade-off between big brains, bipedalism and the limits of motherhood.

The evolution of the human species is marked by an increase in brain size. Now new research suggests that could be partly ...

The human body is a machine whose many parts – from the microscopic details of our cells to our limbs, eyes, liver and brain – have been assembled in fits and starts over the four billion years of our ...

Human evolution has long been tied to growing brain size, and new research suggests prenatal hormones may have played a surprising role. By studying the relative lengths of index and ring fingers — a ...

Fossils unearthed in Ethiopia are reshaping our view of human evolution. Instead of a straight march from ape-like ancestors to modern humans, researchers now see a tangled, branching tree with ...

The evolution of the human species is marked by an increase in brain size and research suggests that could be partly dependent on increases in prenatal oestrogen. As individuals with high oestrogen ...

If we look across the whole of the mammal branch of the tree of life, we find there are many groups of mammals that have ...
