Evolution is almost entirely mistakes.

i had a point on this.... what was it...

oh yeah, as we go through life frustrated by man's apparently inherent nature to rush into mistakes of all imaginable sorts, perhaps we should instead be thankful for it. it's that nature that finds the answer. without that nature, timidity would probably rule and would therefore make the species less fit.

of course we're also rushing into our own extinction via technology, but that assumes FNYIE (facts not yet in evidence) and so we'll ignore it for now.
