After studying 6,000 human skulls from academic collections around the globe, British scientists have come to the conclusion that humanity originated from a single point in Africa. This disproves the opposing theory that the roots of humanity began in different areas of the planet.

"We have combined our genetic data with new measurements of a large sample of skulls to show definitively that modern humans originated from a single area in Sub-Saharan Africa," says Andrea Manica, a researcher from the University of Cambridge's Zoology Department. In her team's article in the Nature journal, they claimed that their study showed a decrease in variations to a skull's size and shape the further it got from that point in Africa.

Scientists agree that the team's findings are important for in confirming the theory that humanity's current diversity came from one source rather than multiple locations. Furthermore, breeding with other early human groups like Neanderthals were found to be either non-existent or insignificant to affect the evolution of man. The findings reflect that only a few number of our ancestors left Africa, effectively creating "bottlenecks" in diversity.
