Personally, I don't buy into evolution at all. Religious biases aside, I think we'd notice if evolution was at work in changing species beyond simple adaptations to different environments. Never once in recent history have we witnessed any new species develop from existing ones.
The theory of evolution does not pretend that new species emerge quickly, certainly not in the tiny timeframe of human existence where word was not only written but also trustworthy. (e.g. in the past not only would a recording of a newly formed species not be very trustworthy, it might also simply be a newly discovered but quite lengthily-existent species) Therefore, while we do not see new species emerge if we study fossil records we can see it happening, or so goes the theory.
I believe I may be slightly derailing the thread...
Two noteworthy examples of evolution
in our lifetime are the cases of sickle cell anemia and the peppered moth. Sickle Cell Anemia is a red blood cell defense that effectively prevents Malaria. In those areas of the world where Malaria is more rampant, Sickle Cell Anemia is also more widespread. At the beginning of the Industrial Revolution, the peppered moth was a white moth that lived in the British Isles. As the Industrial Revolution progressed, pollution covered trees near factories in soot, killing off its lichen. Predators had a harder time spotting the moths against the sooty bark. Black peppered moths thrived near Industrial centers as a result.

And to say nothing of Bacteria and Viruses that become resistant to vaccines and antibiotics...
