Why are diseases more common in some parts of Europe than others, and why are northern Europeans taller than their southern counterparts?

The genes which protected our ancestors from animal diseases now raise the risk of multiple sclerosis (MS).
The researchers call their discovery "a quantum leap" in understanding the evolution of the disease.
