New study: Can the introduction of oxygen explain the Cambrian explosion?

Do you remeber the episode of Knight and Rose Show where we interviewed Dr. Günter Bechly about the Cambrian explosion? We were talking about naturalistic explanations for the explosions of new information at certain points in the fossil record. I mentioned that one paper had argued that the introduction of molecular oxygen into the early Earth’s atmosphere might explain the origin of all these new body plans and organ types.Well, before we see the new paper, let’s start at the very
