The (sort of) evolution of the Lake Constance stickleback

In a lake in Switzerland lives a small fish called the Lake Constance stickleback. This is a very special fish, which has been evolving into two distinct sub-types within the lake – one that lives in the lake, the other that lives in the surrounding streams. Both types breed at the same time in the same place, but breed separately.

This is touted as an example of extremely fast evolution, with this change beginning only 150 years ago, and already having visible results. How true is this, and what does it mean for the evolution vs. design debate? Well, let’s find out.
