Ah, even here at the Thanksgiving house away from home, the first thing I turn to in the a.m. is The New Scientist. Weekend reading. And it didn’t disappoint. Would you believe a theory that, three billion years ago, theorists are beginning think that the Earth had one enormous mega organism that kept splitting (into three) and because the uber mother/father of all others?
My question is — who created Luca : )

ONCE upon a time, 3 billion years ago, there lived a single organism called LUCA. It was enormous: a mega-organism like none seen since, it filled the planet’s oceans before splitting into three and giving birth to the ancestors of all living things on Earth today.
This strange picture is emerging from efforts to pin down the last universal common ancestor – not the first life that emerged on Earth but the life form that gave rise to all others.

Too wild. Science! Great job reporters at The New Scientist.
