Unfortunately, I have not seen any citations to
back this up. Which Arens, where
Unfortunately this Discovery article (which also rehashes several arguments
that were refuted long ago) doesn't mention if Arens made any attempt to get
things like the Signor-Lipps effect and local variations of the environment
to find the gradual decline in the number of angiosperm and mollusk species
(interestingly 90 % for both). I don't assume Arens is stupid, so I'm sure
he did something, but how much, and what?
Strange that the article mentions a _trans_gression where everyone else
mentions a _re_gression.
