Without intending to get involved in this huge debate, I have one question: I was at a science museum yesterday (Imagine that!
) and there was a sign about dragonflies, saying they evolved 340 million years ago, and have kept changing ever since, and so forth.
My question is, how could they possibly get that figure? Dragonflies are insects, and so they don't have bones, so they couldn't even leave fossils. Anyone have any idea how they got that date?
