For each of the examples, simple diffusion, carrier, and channel mediated, each type involves the flow down a concentration gradient. This means that the molecules flow from an area of high concentration to an area of low concentration. In turn, this allows for a passive process, meaning no ATP is needed! I hope this explains your question.
The environment can influence the evolutionary changes so that the organism will be best suited to survive in that area. Genes that are useless in that specific environment will eventually be replaced with more useful traits as the species evolves.
Hope that helps
