Sometimes, the best way to debunk a story is to read it. Case in point: The story about the discovery of ancient pyramids in Antarctica. Recently, this tale of intrepid explorers discovering a series of man-made structures on a continent that has been too harsh to support sustainable human life for millions of years went viral over the Internet.
The story was picked up by many news outlets and blogs throughout the world, and has made its way as a meme on Facebook and other social media sites. By all accounts, this story would sound like the greatest archeological discovery of a lifetime.
However, nearly everything about this article, including the pictures and descriptions of the “explorers” hint that this was merely a hoax. Even the news outlets that ran with the story are suspect. Whatever the case may be, the story is its own undoing.
The Bermuda Triangle has the reputation as the home of numerous disasters and disappearances, but could it also be home to the lost city of Atlantis?

Spawning Conspiracy Theories

Wheat was first domesticated in southeastern Anatolia perhaps 11,000 years ago. (An archaeological site in Israel, called Ohalo II, indicates that people have eaten wild grains, like barley and wheat, for much longer — about 23,000 years.)
Is this enough time to adapt? To answer that question, consider how some populations have adapted to milk consumption. We can digest lactose, a sugar in milk, as infants, but many stop producing the enzyme that breaks it down — called lactase — in adulthood. For these “lactose intolerant” people, drinking milk can cause bloating and diarrhea. To cope, milk-drinking populations have evolved a trait called “lactase persistence”: the lactase gene stays active into adulthood, allowing them to digest milk.
Milk-producing animals were first domesticated about the same time as wheat in the Middle East. As the custom of dairying spread, so did lactase persistence. What surprises scientists today, though, is just how recently, and how completely, that trait has spread in some populations. Few Scandinavian hunter-gatherers living 5,400 years ago had lactase persistence genes, for example. Today, most Scandinavians do.
Here’s the lesson: Adaptation to a new food stuff can occur quickly — in a few millenniums in this case. So if it happened with milk, why not with wheat?
