<span>The scientist, Dimitry K. Belayev, was trying to prove that dogs's physical traits- and morphological traits- were changed by natural selection. He thought that the dogs that were friendliest towards humans were selected, and that changed them. To prove it, he domesticated an animal which is very similar to a dog, a fox.</span>
Human evolution and natural selection reduce susceptibility of disease. A simple explanation would be saying that the life forms that are not immune to the disease pass away, then the ones that are immune or survive genetically give this trait to their offsprings, leaving only life forms that are immune. This does not occur so easily and is a long process, but it is a simple explanation.
