Since Humans evolved & were once stupid?...Does that mean

That each species has the potential to eventually evolve into one as smart & capable as us? I know it would take a very long time but wouldnt that make sense that they would also figure out things that we have & adapt to better suit themselves & their kind?

Evolution is not directional. There is no goal toward which we are all moving. It is about survival and adaptations that increase the likelihood of survival. Our particular species developed intelligence as our trait which allowed us to survive. Tigers developed sharp teeth and claws. Anteaters developed long tongues. Humans and tigers and anteaters all have tongues, claws (nails), teeth, and intelligence, but each of those species specialized in one or another as a means of survival. Anteaters have the ability to evolve heightened intelligence, but only if their circumstances change in a way that requires them to solve more complex problems than they do today; otherwise they will remain anteaters.

Not necessarily.

Evolution has no specific direction, the ultimate goal is not to create an intelligent organism. The result of evolution is the creation of an organism that is more suited to survive in their niche, based off of the genes that have become available to them through series of mutations. This may involve something like larger gill surface area, as in a fishes case, or a longer neck, as in the giraffe's case.

what makes anyone think that humans are the most inteligent,it could be the most inteligent is a animal that is free and in its own enviroment that we are not happy in such as dolphins that maybe treat us as pets.who knows

Humans never evolved they came from God duh.

Nice theory and I agree

Possibly, but I think we would try to stop them; we don't really want competition, do we?
