And Speaking Of Evolution...
First is the California insect species discoveries. Those creepy-crawlies are really interesting, for a lot of reasons. The amount of specific adaptation is truly fascinating.
Second is a bit of a sadder note. It concerns the adaptation of killifish to the toxic waters of New Bedford Harbor, Mass. This wouldn't be so disturbing if it weren't for the fact that these will continue to introduce the toxins into the food web for decades or even centuries to come, and there's very little we can do to stop it in the foreseeable future.
Edit: Wow, I just realized this is my 200th post. And right after my birthday, no less. Sweet!
