“Evolution is all about processes that almost never happen. Every birth in every lineage is a potential speciation event, but speciation almost never happens, not once in a million births. Mutation in DNA almost never happens — not once in a trillion copings — but evolution depends on it. Take the set of infrequent accidents — things that almost never happen — and sort them into the happy accidents, the neutral accidents, and the fatal accidents; amplify the effects of the happy accidents — which happens automatically when you have replication and competition — and you get evolution.”

About

There are no records of Roosevelt having made such a statement, and this is most likely a misquotation of the widely reported comment he made in a speech at the Citadel (23 October 1935):
: Yes, we are on our way back — not just by pure chance, my friends, not just by a turn of the wheel, of the cycle. We are coming back more soundly than ever before because we are planning it that way. Don't let anybody tell you differently.
