In what is believed to be the first major science gathering on a First Nation in Canada, researchers from across the country will come together June 3-6 for the inaugural meeting of Global Water Futures on the Six Nations of the Grand River and at McMaster University to discuss critically important issues related to Canada's freshwater resources.
The Sahara Desert has long been considered a forbidding and impenetrable barrier to human migration from southern Africa, but new evidence suggests there were three brief intervals of time when it transformed into a vast green savannah which provided the ideal conditions for the early movement of ancient humans.
According to scientists at McMaster and the University of New Mexico, one of those intervals coincides precisely with the age of the oldest known remains of modern humans—dating back roughly 315,000 years ago—which were discovered recently by another team of researchers in Morocco.
