Re: [asa] geological dating

I'm puzzled as to why you say, "regardless of biological evolution." How could there be index fossils if there was not a monotonic variation in organisms? And such monotonic variation is evolution by definition.

  The fact that certain types of fossils are observed in particular
  layers and not others and can be used as index fossils is an
  observation that stands regardless of biological evolution, despite
  various young-earth attempts to deny it.

  However, biological evolution gives the reason for the changes and for
  why things do not appear, disappear, and then reappear the way they
  might if different types of organism were being created from scratch
  and put on earth.
