"Our results provide the first full picture of the whereabouts of the ancestors of all present-day non-Africans in the early phases on the colonization of Eurasia," said molecular anthropologist Luca Pagani of the University of Padova in Italy, senior author of the study published in the journal Nature Communications. Anthropologist and study co-author Michael Petraglia, director of the Australian Research Centre for Human Evolution at Griffith University, said the study "is a story about us and our history - our goal was to unravel some of the mystery about our evolution and our worldwide dispersal." "The combination of genetic and paleoecological models allowed us to predict the location where early human populations first resided as soon as they exited Africa," Petraglia added.
