I have tried to stay out of the Creaion/Evolution debate because in general I think it does more harm than good. But this article has the potential to drive the debate for the next decade. Evolutionary biologists claim to have actual observations of speciation in action. A species of fish in Lake Victoria appears to be diverging into two different species, based on pollution which is changing how they hunt and are hunted.
It should be noted that if this is true, then it is fundamentally different from the "coal moth" experiment which to now has been held up as the best experimental evidence of macroevolution in nature. That was simply a case where location conditions changed the proportion of dark and light moths in a population. This case instead may actually show one species becoming incapable or unlikely to ever interbreed.
