Remember, ALL of the topics we discuss are linked to ALL others either tightly or loosely. We can discuss the fossil finding curve separately -- in fact I think it should have its own topic but in the fossilization topic is at least somewhat separated out. It will have value in discussing a lot of other topics than whales.
Remember that every single topic gets discussed over and over after a few months. Having them organized in a way which makes finding and referenceing them easier might save time in the future.
When that is resolved (however unlikely that is) we can bring the answer back here.
Meanwhile we can discuss other issues which randman has brought up.
