Sorry, I imputed “immediate” to the term unnecessarily.
Well, organisms which only meet some definitions of intelligence are subject to natural selection - the intelligence of evolution is merely a metaphor. I think the example Dawkins gives in “The Selfish Gene” is that a human doesn’t need to be aware of the physical formulae involved in motion to be able to catch a ball and animals or plants may alight at complex selection strategies without conscious awareness of them.
