Isn't Time a rather loose source in this instance? While all my books are
in storage, I believe that the following phyla do not appear until after
the Cambrian. I agree with Susan, plants are new body plans. There is also
the cycliophora which was found on lobster lips this decade and is a new
animal phyla.(Petar Funch and Reinhardt Mobjerg Kristensen, "Cycliophora is
a new phylum with affinities to Entoprocta and Ectoprocta," Nature, 378,
Dec. 14, 1995, p. 711). Why did God create the animals in almost one fell
swoop but then dribble out the plants? This would imply that change can
occur, contrary to some of your quotes.
