Whats your point? No living thing is perfect. And because of this fact, some are better than others, and either adapted to it's enviroment. (Lamarck) or the fitter species survived because of one trait or another was superior to another. (Darwin)
Perfect examples of this are Giraffe and Artic Fox. Giraffe's neck became more and more elongated each generation after geneartion because of the abundance of food supply higher in the trees. Species with shorter necks died out becase of starvation. Artic Fox on the other hand probably started out as brown or red foxes. But as time went on, some foxes where born with wite fur. The white fur was an advantage over the borwn fox because it could camouflauge it self in winter. The animal that was less threatened by preadetors eventually was the more fit species than the one that waqs wiped out by predators.
Is this by design? Probably not, and for a matter of fact,, small scale evolution similar to these examples have been proven in labatories with microbles and bacteria. If humans where able to conduct an expirement over thousands of years we could produce similar results with larger animals that have a shorter life span, but unfortunately, humans only live 50-80 years on avaerage. So we will never see this process up front.
