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.
The latest results suggest LUCA was the result of early life's fight to survive, attempts at which turned the ocean into a global genetic swap shop for hundreds of millions of years. Cells struggling to survive on their own exchanged useful parts with each other without competition - effectively creating a global mega-organism.
So, how can LUCA be the start of all life on earth? Wouldn't "early life" be the common ancestor? I'm ashamed to admit I didn't read the article, so feel free to mock if it's deserved.

Oh snap! I thought you said it was because of a Planetary Orgasm. This thread could have been so much more interesting. It would have also solved the "Unexplained White Goo" that has showed up in a few places....
