It's actually market forces. Evolution has almost zero to do with it. It's the past few thousand years where the vast majority of useful abstractions/tools/puzzle pieces have been built that enable any one person to do a lot without knowing so much.
replyMarkets and evolution are both knowledge processes. I think you would enjoy Donald Campbell's essay on evolutionary epistemology from 'The Philosophy of Karl Popper'.
replyParent's comment is observing a prerequisite to markets, humans are the only animal with global markets and biological selection happened to produce the kind of creature that can stabilise around markets.
It's also selection that produced the current form of markets themselves. The world could have been otherwise; our current markets are contingent selection products, not analytically necessary institutions, and not guaranteed to be the uniquely best mechanisms for producing abstractions and tools.
Selection pressure in general. It's not market forces that decide military viability of one empire over another but it's not biological evolution either.
