The algorithms predicted where common ancestors must be present in the evolutionary trees to explain the patterns of genetic variation. The resulting network contained almost 27 million ancestors.
After adding location data on these sample genomes, the authors used the network to estimate where the predicted common ancestors had lived.
The results successfully recaptured key events in human evolutionary history, including the migration out of Africa. [...]
Dr Yan Wong and Dr Wohns said in a joint statement: 'These ancestors lived up to and over one million years ago – which is much older than current estimates for the age of modern humans (c. 250,000 to 300,000 years ago) – so bits our of genome have been inherited from individuals that we wouldn't recognise as modern humans, but who most likely lived in northeast Africa.
