Andrew Knoll's Opinions

Mostly Disagree
Our sense has been that while Mars is a lousy environment for supporting life today, long ago it might have more closely resembled Earth, but this result suggests quite strongly that even as long as four billion years ago, the surface of Mars would have been challenging for life. No matter how far back we peer into Mars' history, we may never see a point at which the planet really looked like Earth.
