Why Darwin's Theory is being questioned?

Re: Why Darwin's Theory is being questioned?

There is distinct and very obvious proof of evolution and its sister natural-selection in the quick and visable mutation of viruses and bacterium. Its a case of simple extrapolation.

There are also very obvious examples of the evoution of various other species in fossils and rocks. You can literally put them in order and see how they progressed and adapted to better suit their environment. Why are we still arguing this again?
