Re: What is a Dinosaur?

It seems like people are arguing, but saying the same things on both
"sides".

DEFINITION (node-, stem-, or apomorphy-based): stable

DIAGNOSIS (characters): not necessarily stable (except for apomorphy-based
clades, in which case one diagnostic character is stable)

CONTENT (organisms): not necessarily stable (except for internal
specifiers)

Pretty obvious, and I don't see what the fuss is over.
