How evolution creates problem-solving machines | Michael Levin

TL;DR

Evolution is about problem-solving machines in biology that adapt to changing environments efficiently.

Transcript

• When most engineers hear about the theory of evolution for the first time, the reaction is one of incredulity. And that's because anybody who's ever made anything from writing a computer program to building a complicated device, you know that it's entirely likely that random changes that you make to that system are not gonna make things better, t...
