An evolving of consciousness?

Wonder where that whole consciousness (higher, lower) idea came from… Is there an evolving of consciousness: that which we are conscious of; evolves? Does that make sense?

I’ve heard of the evolution of intelligence too. Isn’t intelligence simply gathered… The intellect as the product of gathering information? What could actually evolve, as far as people are concerned? Better lungs? Better eye sight? Is that evolution?

I could go with a statement like, “One idea evolves into more ideas, new or better ideas”. I guess this evolution of consciousness is the Darwinian idea of consciousness.

I really don’t like the Darwinians
