"'We saw a large speedup, for instance, when we repeatedly exchanged an 'OR' for an 'AND' in the computer code defining our goals, thus changing the relationship between subgoals." The quote from the article available here, indicates an important feature of how we innovate.
The above simulation of the human evolution showed a speed by changing conditions (choice) of this Vs That to This AND That. We want both - want to have the cake and eat it too. This is exactlly what Altshuller, the creator of Theory of Inventive Problem solving (TRIZ) found - the best inventions are those that provide both the capabilities of the contradictory parameters of a system.
This he found is a thinking method to speed up the process of finding Innovative solutions to inventive problems!!!
