This is mostly just terrible writing, confounding senses of 'plan'. But in
support of Art's point, when I listened to the NPR show, I heard that the
lack of mention of the Cambrian explosion in the textbooks had been
explained away on the grounds that this was too new an item in the
science. That is pretty bizarre.
