Oct. 4, 2013 — The mystery of why life on Earth evolved when it did has deepened with the publication of a new study in the latest edition of the journal Science.
Something to do with the faint young Sun paradox.
Life evolved on Earth during the Archean, between 3.8 and 2.4 billion years ago, but the weak Sun should have meant the planet was too cold for life to take hold at this time; scientists have therefore been trying to find an explanation for this conundrum, what is dubbed the ‘faint, young Sun paradox’.
Suppose you could think of reasons but the reasons are officially deemed “not science.”
Well, who’s the loser there?
