The Economist is a running a story today about fish adapting to live in toxic environments. For years we dumped PCBs into oceans and rivers all over the world, until it was banned in most countries, because of its damage to aquatic life. We banned it here in 1977. Unfortunately, PCBs hang around a long time. Yet some researchers at my old Alma Mater, NYU, have been studying fish that have evolved ways to defend against the toxins.
This is an incredibly interesting story on a number of fronts. It absolutely proves evolution and spits in the face of the morons who spent millions to build the Creationist Museum who claim God made us all about 7000 years ago, that the universe is just slight of hand, like a stage prop made to look billions of years old, and that we were chilling with the Dinosaurs, riding on their backs and giving them treats.
On the other hand, it also gives some credence to global warming doubters, like my friend Peter, who will no doubt comment on this article, despite the fact that we’ve seen a wave of news on global warming recently even from skeptics. How? Because it basically says that nature finds a way to adjust. Peter’s theory is that we can’t really damage the environment; the environment will take care of itself. I think he’s right in many respects. The problem is that we just aren’t guaranteed to survive when nature resets itself. Nature will make a correction. But like people losing all their 401K cash in a stock market correction, there are always big losers in any correction. Ask the dinosaurs.
