<<Why is there so much discussion about such particulars and so little about the Cambrian explosion, the most amazing event of all? Is it because this event has come to be just synonymous with evolution itself, rather than being an object of scientific study?>>
Good question. I believe that one can always find issues which we do not (yet) understand fully. Yet does this mean that evolution could not have happened ? Of course not.
What interest do you have with the Cambrian Explosion ? From what I understand, this is indeed a remarkable era and has received significant scientific study. So what would you like to discuss about the Cambrian Explosion that you feel has not received just examination ?
