Since Darwin published his theory there have been many experiments made 
to test it. Some are under way right now, several that where started way 
back then.

Some preliminary results show mice and others that diverged from a 
common stock so much as to be incapable to cross breed. Including with 
decendents of the original population that lived under normal conditions.
You have mice that lived in total darkness, or high temperature, of near 
freesing temperature, with very scarse food, almost no water, to much 
water, that need to travel long distance to get food and water,... for 
over 200 generations and counting.
You also have insects subjected to such environments for over 1000 
generations.

We have created entirely new and distinct species that way.

Those very long term experiments are proving the validity of the theory.
