While on a hike in the Adirondacks last week, my wife and youngest daughter took this picture of what should be a green frog. I have never seen this blue pigmentation before. I think it’s unlikely to be a mutation that will impart any kind of advantage unless it finds itself living on a blue carpet, and come to think of it, being blue in that case might not be an advantage.

Frog populations are in decline all over the world. Evolution is expedited by changes in environment but if changes are too rapid, mutations won’t keep up and extinction will result. Anyone else out there seeing blue frogs?
