Anthropologists believe early humans evolved in Africa and then moved out from there in successive waves. However, what drove their migrations has been a matter of conjecture.

One new explanation is climate change.

Anthropologist Anders Erikkson of Cambridge University in England says the first few hardy humans who left Africa might've gone earlier but couldn't. Northeastern Africa — the only route to Asia and beyond — was literally a no man's land.

An apple a day might keep the doctor away, but what do you do when there are no apples? It's a question western Michigan's apple growers are dealing with this season after strange weather earlier in the year decimated the state's apple cultivation.

Michigan is the third-largest apple producer in the U.S. after New York and Washington, but the state's apples will soon be in short supply. Now in the middle of harvest season, growers are picking only 10 percent to 15 percent of their normal crop.

Canada's leaders have ended their country's longstanding resistance to asbestos being called a dangerous material under United Nations guidelines, a decision that reflects a shift in the leadership of Quebec province, home of Canada's asbestos industry.

Quebec's incoming premier, Pauline Marois, promised late in her campaign that she would shut down the region's asbestos mines for good. She says that she will use money that would have gone to restart the mines to diversify the local economy.

During his 2008 presidential campaign, Barack Obama ran on the platform of "change we can believe in" — but he has a different approach to the Supreme Court's interpretation of constitutional law.

"Obama is a great believer in stability — in the absence of change — when it comes to the work of the Supreme Court," Jeffrey Toobin, author and senior legal analyst for CNN, tells Fresh Air's Terry Gross. "He is the one trying to hold onto the older decisions, and [Chief Justice John] Roberts is the one who wants to move the court in a dramatically new direction."
