Got a mouthful of metal and stack of orthodontic bills? You can thank your farmer ancestors for them.
That's according to an anthropologist who says the switch from chewing wild game to eating corn, rice and wheat could have shortened the human jaw so that teeth don't fit in it as well.
When agriculture took off in some parts of the world, it had a lot to offer people: Farmed foods are a more reliable source of calories, and are easier to chew and digest. But they also may have helped transform the jaw bone before the teeth could catch up.
The next presidential election in Iran is scheduled for 2013, but doubts are emerging about whether it will actually take place.
A conservative member of Iran's Parliament recently claimed that a secret committee convened by Iran's supreme leader, Ayatollah Ali Khamenei, has been working on a plan to do away with the office of the presidency.
Meanwhile, the conflict between the supreme leader and President Mahmoud Ahmadinejad continues to sharpen.
For the not-so-super debt reduction supercommittee, failure is clearly an option.
As the blame-gaming bipartisan congressional committee stumbled toward collapse Monday, washing out on even the most basic show of common purpose, the "what happens next" scenarios began to take shape.
President Obama has kept his distance from the supercommittee. Unlike the budget battles earlier this year, there were no bargaining sessions at the White House. No presidential motorcades to Capitol Hill.
Rep. Kevin McCarthy, the No. 3 Republican in the U.S. House of Representatives, has a very clear record on the Affordable Care Act. He has repeatedly called for its defeat and was one of the co-sponsors of the January repeal measure that easily passed the House but died in the Senate.

John Pike likely never thought that video of the incident would go viral on the Web, that there would be outrage not only at the school but around the nation, or that "casually pepper spraying cop" would quickly become one of the year's top memes.
The United States government takeover of American International Group saved the company from going under during the financial crisis of 2008. As The Wall Street Journal reported at the time, the government drove a hard bargain — tens of billions would get it an almost 80 percent stake of the company — but the government argued if AIG went down, so would the rest of the economy and AIG argued if the company wasn't pumped with money, it would collapse. The U.S.
With the members of the congressional deficit-cutting supercommittee essentially announcing that they couldn't get to "yes," the nation is only seeing the latest turn of the screw in the partisan paralysis gripping policymakers in Washington. We all know it is far from the last.
Coming as it does now less than a year before the 2012 general election, the panel's failure to achieve at least $1.2 trillion in deficit reduction means each major political will now be focused on trying to persuade voters that the other party is more responsible for the impasse.
