On the Trail of LUCA

It's called LUCA - shorthand for the "last universal common ancestor" - and they think it inhabited the Earth 3 billion to 4 billion years ago. Some scientists are using new advances in the science of genetics to track it down and think they are getting close. Other scientists think there may be other explanations.

Funny, none of the "experts" who testified at the Kansas science hearings in May mentioned LUCA. In fact, as RSR recalls, each of the "experts" at the hearings told attorney Pedro Irigonegaray that they doubt common ancestry alltogether -- heck, they don't even think humans descended from prehominids.
