>>There has been some posts about organisms that have not shown a lot of
change over quite a bit of time. Let me indicate, as someone who
studies fossils (Carboniferous Coal Swamps), that long periods of stasis
little change in a taxon is a very real thing in the fossil record and
not limited to the few examples of Ginkgo or horseshoe crabs. <<
I will fully agree that plants evolve at a slower rate, but you obviously
didn't look at the drawings of horseshoe crabs I put on my web page. There is
nothing static about them!.
look at http://www.isource.net/~grmorton/crabs.gif
And I will point out that in the Oligocene Lake Florissant beds, there are no
no modern species of plants. See Macgintie's 1953 work.
