Evolution in Action

"But the most important point is this: viruses and other pathogens evolve in ways that we can understand and, to some extent, predict. Whether it's preventing a flu pandemic or tackling malaria, we can use our knowledge of evolutionary processes in powerful and practical ways, potentially saving the lives of tens of millions of people. So let's not strip evolution from the textbooks, or banish it from the class, or replace it with ideologies born of wishful thinking. If we do, we might find ourselves facing the consequences of natural selection."
