Yes. What I meant was nature doesn't generate a mutation based on thinking through what is good for the species or individual. The mutations just happens randomly and the ones which are beneficial continue to pass through because it ended up in the genes that reproduced. Unlike designing a plane for example which consists of thousands of decisions carefully thought through based on a human objective.
