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.
Believe it or not, there's a lot of food involved in wet-plate photography. Egg whites (albumen) are used to make the glass plates adhesive to the light-sensitive chemicals.

Just a reminder now that Round 9 of our Three-Minute Fiction Contest is open. It's where we ask you to write an original short story that can be read in about three minutes, so no more than 600 words. In each round, we have a judge with a new challenge. And this time, it's novelist Brad Meltzer, and he's come up with this.

Pennsylvania's politically split Supreme Court is considering a challenge to a lower court ruling that upheld the state's polarizing voter identification law.
The law requires a state-issued photo ID card to vote, and supporters say it will help prevent voter fraud. Voting-rights activists have now shifted strategies from attempting to overturn the law, to instead putting up to a million state-issued photo ID cards in the hands of residents.
State officials recently estimated it is possible nearly 200,000 Philadelphia residents alone don't have proper ID.
We've heard much about big money pouring into some of the congressional races around the country, and now some of that money is breathing new life into the campaign of one unlikely candidate.
Rabbi Shmuley Boteach, author of books such as Kosher Sex and Kosher Jesus, and the host of Shalom in the Home, a reality show that worked with struggling couples, is running for Congress in New Jersey's 9th District.
Boteach is hoping to unseat Democrat Bill Pascrell in a district that is overwhelmingly Democratic.
