Proof of Evolution: Evolution Observed

This is evolution observed in tuberculosis. The antibiotic works as environmental change or a predator. The reason we can observe tuberculosis evolve is because of the pressure put on it by the antibiotic and the rate of reproduction. We don't expect to see such changes as quickly in mammals and such, because of the rate of reproduction and stable environments. We can only observe this sort of evolution taking place on a larger scale by looking at the fossil record, as the process is much slower due to the rate of reproduction and environmental changes. And if we look to the fossil record what do we see? We see gradual change, just as predicted. The evolution of bacteria is evolution in high speed, whereas animal species evolve much slower. The accumlated changes in tuberculosis are gained much quicker due to the antibiotic pressure and rate of reproduction. Now, look to the larger scale animals and imagine small accumulating changes over hundreds of millions of years due to environmental changes and reproduction. Again, the fossil record shows gradual change throughout the strata. That is why you'll never find a modern bald eagle with the feathered dinosuars like Epidexipteryx. They never lived together, but these feathered dinosaurs slowly evolved over millions of years accumulating small changes, and if those small changes are added up over millions of years you find amazing change and variety. The fossil record is consistent.
