So, there you have it--evidence of evolution, including change from one species to another and change from one genus to another.
Hi Coyote,
Maybe you can clear something up for me.
My glossary of geology defines species as "a group of organisms, either plant or animal, which may interbred and produce viable offspring having similar structure, habits, and functions."
In your quote above and the repost of message 5 you appear to be telling me that P. ralstoni and P. trigonodus ( as an example)are not capable of interbreeding and producing viable offspring.
What exactly is your fossil evidence for taking this position?
