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.
Since 2008, the North Carolina band Holy Ghost Tent Revival has been crafting a sound rooted in its members' Southern upbringing. Along the way, it's made the transition from playing acoustic bluegrass and folk to becoming a soul-rock horn band that recalls '60s and '70s classic-rock influences such as The Band and The Flying Burrito Brothers, contemporary indie-rock acts like Dr. Dog, and New Orleans brass-band jazz.
