The new research suggests that life existed prior to the massive bombardment of the inner solar system that formed the moon's large craters 3.9 billion years ago.
"If all life on Earth died during this bombardment, which some scientists have argued, then life must have restarted quickly," said Patrick Boehnke, a co-author of the research and a graduate student in Harrison's laboratory.
Scientists from Stanford University and the University of California, Los Angeles said they recently collected some 10,000 multibillion year-old zircons in Jack Hills, Australia, including one believed to contain a carbon deposit that is 4.1 billion years old, give or take 10 million years.
The research suggests life in the universe could be abundant, Harrison said. On Earth, simple life appears to have formed quickly, but it likely took many millions of years for very simple life to evolve the ability to photosynthesize.

Just think what could have happened in one billion years before the bombardment.
Life could have evolved to the limits we are at today 5,000 times over during this period.
Look how far we've come this time around in just the past 200,000 years.
I don't know what you are talking about. If the OP is true, humans are at the tail end of 4.1 billion years of evolution. Meaning that we couldn't get to where we are now without all those evolutionary changes stacking up over time.

"Life on Earth may have started almost instantaneously. With the right ingredients, life seems to form very quickly."
-Mark Harrison, UCLA
Yup. Now take the superfluous 'billions of years' out of the theory.

You really still equate evolution to abiogenesis? Some people just shouldn't comment on things they have no clue about. Do us all a favor and stick to posting fake Photoshopped dinosaur pictures and claim they are dragons.

Well, the earth formed near 4.5 billion years ago and this study is referencing 4.1, so it's only 400 million years between the formation of earth and the first life. I very much doubt that life could have evolved to where we are today in that short of a time, in that given environment. Most life on the planet today could not survive those type of conditions and it took near 1 billion years for single cells to become multi-cellular organisms. I'd agree with you if not for the bombardment period. It would take extreme type of lifeforms to survive that period and humans simply are not built for that. A billion years with the earth's current conditions, I'd agree that it could happen.
