The basis for evolution is survival value. One advantage for man is the opposable thumb. That's why cows aren't interested in Ipad's. You need two thumbs to operate them effectively.
A dog species has survival value if it can hunt or sniff stuff. The best sheep herding dogs were breed for that trait. That is artificial evolution. Your loving dog is probably here because it's progenitors probably didn't bite the hand that fed them.
Some dolphins are extremely intelligent, but in their history, they failed to learn how to operate laths, milling machines and punch presses. Therefore they could not invent the engine even though they sorely wanted to when they saw jet skis whizzing overhead.
On a more serious note, there were competitors to man's intelligence, why they became extinct is controversial. It could be genocide by the Homo Sapians, who are noteworthy for doing such things. Or it could be competition for the same resources for which we are also noteworthy.
There were many intelligent primates. Neanderthals died off fairly recently.
Homo Erectus (named after their erect stature, and not an erect body part) died off over a million years ago. They made simple tools such as screwdrivers and allen wrenches. For a perhaps fictional account of competition between intelligent species see Planet Of The Apes, episodes, 1,2,3,4,5,6,7,8, and 9.
I think I read too much Science News.
I love your style. Nice to mix factual information with humor!
