Did you ever wonder why Downy and Hairy Woodpeckers look so much alike? No? Neither did we, but it was because we always assumed they were just closely related species. Maybe you did, too, but thanks to the wonders of DNA analysis, we now know that these two look-alikes are not even in the same genus. So, what gives?

Researchers recently looked into this stumper-of-a-problem, and, in this episode, Bill and Steve break down what might be the cause.

Oh, and Bill talks about how he might have Lyme disease.

Enjoy!
