Some Important Evoutionary Changes in Species - In the Past 40 Years

Last week, I discussed how evolutionary biology has changed since 1859, the year Darwin first published "On the Origin of Species." But the subject of evolution isn't the only thing that's changed since then. There's been plenty of actual evolution, too. For although we tend to think of evolutionary change as being something that only takes place over the course of millions of years, it isn't. It's going on here, now, all around us. So, this week, I thought I'd round up some examples of recent evolutionary change in nature. (What do I mean by recent? Within the last 40 years.)
