I always knew there was something about Thomas Jefferson I didn’t like:

Now, new techniques have been brought to bear on Jefferson’s Y chromosome, in a study reported in the American Journal of Physical Anthropology. The presidential chromosome turns out to belong to a rare class called ‘K2′, which is found at its highest frequency in the Middle East and Eastern Africa, including Oman, Somalia and Iraq. Its closest match was in a man from Egypt. Could this mean that the President had recent ancestry in the Middle East?
