Signs of this mysterious early migration remained in the DNA of the Neanderthal who left the leg bone behind, revealing not only a previous tryst between the two hominin populations, but a sign that Neanderthals were far more diverse than we thought.

The skeleton, along with others of the species found so far only at Malapa, are responsible for setting off a new golden age of early hominin fossil discovery in South Africa.

More recent fossil discoveries in the same region, including the iconic 3.7 million year old Laetoli footprints from Tanzania which show human - like feet and upright locomotion, have cemented the idea that hominins (early members of the human lineage) not only originated in Africa but remained isolated there for several million years before dispersing to Europe and Asia.

Once early hominins had boosted their metabolism and grown bigger brains, he says, natural selection would have favored not only fatter individuals, but also smaller guts and other energy - saving adaptations, such as cooking and efficient walking.

I alluded earlier to some putative hominin remains dating back as far as seven million years but those were only known from a skull in one case and some teeth and limb bones in another case, and Ardipithecus is a partial skeleton with many, many, many bones preserved.

Over the last few decades, however, as subsequent discoveries pushed back the date for the earliest stone tools to 2.6 million years ago (Ma) and the earliest fossils attributable to early Homo to only 2.4 - 2.3 Ma, there has been increasing openness to the possibility of tool manufacture before 2.6 Ma and by hominins other than Homo.
