Researchers document the movements of giant, which wandered the north more than 14,000 years ago An international team of researchers from McMaster University, University of Alaska Fairbanks and the University of Ottawa has tracked and documented the movements and genetic connections of a female woolly mammoth that roamed the earth more than 14,000 years ago. She travelled hundreds of kilometres through northwestern Canada and Alaska over the course of her lifetime, which ended when she encountered some of the earliest people to have traveled across the Bering Land Bridge. The last remaining woolly mammoths lived alongside the region’s first peoples for at least 1,000 years, but little is known about how the mammoths moved across a landscape increasingly populated by people and w...

New genetic analysis of ancient Africans creates a clearer picture Ancient DNA from the remains of nearly three dozen African foragers—groups associated with hunting, gathering, and fishing—sheds new light on how groups across sub-Saharan Africa lived, traveled and settled prior to the spread of herding and farming. The study involved an international team of 44 researchers including experts from Stony Brook University. The findings, to be published in Nature, produced the earliest DNA of humans on the continent, at some 5,000 to 18,000 years old. The new genetic findings add weight to archaeological, skeletal and linguistic evidence for changes in how people were moving and interacting across Africa toward the end of the Ice Ages. Around 50,000 years ago, distinct groups of forager...
