It might very well have been yes. On one side of the freeze you have just bacteria no the other you have everything we know today. And that this is hard science? > I did a quick-and-dirty wiki check and got the impression Life > arose *despite* the conjectured snowball Earth, not > *because* of it. Can't believe everything you read on the internet I'm afraid. I'm talking about the change from simple single-celled stuff before a major cataclysm to a stronger type of cell (that ALL life now shares) the improvements in cell structure may well have been forced on us by environmental pressure. Bit too much of a coincidence otherwise. > The fact that one event precedes another event does not in > itself make it a "trigger" does it? Or have I misunderstood > you? Probably. In this case you'd have to prove that the freeze *wasn't* the trigger and come up with some other explanation for the arrival of complex life when, for 3 billion years, before a sudden massive change in climate there wasn't any.
