While much is made of the “incomplete fossil record” - why is it that looking at the Cambrian fossils, there are tons of fossils but virtually no fossils of any living animals? And when you look at the fossils of the Jurassic, there are tons of fossils, but virtually nothing immediately recognizable from the past Cambrian and, again, virtually nothing that immediately resembles presently living organisms? And when you come forward in time again to, say, the Miocene, there are tons of fossils, bearing little resemblance to the either the Cambrian or Jurassic? Why is our planet fully populated presently, yet the further back you go in the fossil record, the less all organisms have in common with living ones?
