Evolution, but by artificial selection, so to speak.
Imagine a colony of rats. They all have very tiny differences in their genes, and as these differences neither help nor harm the rat, they are passed along to their offspring as normal.
If someone tries to poison the colony with warfarin, many will die. If any rat's genetics give it a resistance to the poison, then these rats will survive, and pass the resistance genes onto their offspring. Some of these may even be more resistant, etc. So it can be that the entire colony is mostly unaffected by the poison.
Theodore Roosevelt and William H. Taft divided the Republican vote, which allowed Wilson to be elected as a Democrat.
Warfarin works by slowing the blood clotting process down. It prevents the clotting proteins( vitamin K) from doing their job fully. Babies on formula may require higher doses of Warfarin because there is less vitamin K in formula than there is in breast milk. So, the most likely adverse event would be thrombosis since there won't be adequate level of Warfarin in the blood if the dose is not adjusted.
