Video 6 - Why Does Evolution Matter Now

Q:How does evolution work against us with dangerous microbes (little things!)?

A: Evolution works against us because slowly these microbes become resistent to drugs, and then get passed down in generations slowly becoming stronger. This happens because you take a curtain amount of drugs for something. But it can't kill all of it, so eventually if the person stops taking their medicine their future generations are born already with the disease.
