"And another thing" was the title I always gave to science-y stuff that I found interesting. So why not start with one of those. Consider it a way of easing back in to heavier stuff.
So this comes from Smithsonian magazine, which brings news of evolution occurring in real time - in this case, about ten generations.
The study involved was published in the May 21 edition of Global Change Biology and related to Anna's hummingbirds (Calypte anna), a species found in California.
Simply (probably oversimply, so read the article) put, the proliferation of hummingbird feeders since World War II has provided the birds with a plentiful supply of nectar, resulting in longer, larger, beaks - the better to take advantage of the feeders - as well as enabling them to expand their range from southern California up the coast to British Columbia.
So take that, creationists: Yeah, evolution can take tens or hundreds of thousands of years, but it doesn't have to. The argument "no one has seen evolution" just won't wash. Not that it ever did.
