Earliest Primates?

Origin of primates deep in the Cretaceous? National Geographic News, April 18, 2002, article about a new paper. This paper makes me really angry. It is lousy science, and should never have been published. It claims that primates evolved deep in the Cretaceous.

The claim depends on assumptions that include an average life of 2.5 million years for a primate species (go to Chapter 20 and check how that fits with hominids). It lumps together living species (defined by a biological species concept) with fossil species (defined by arbitrary morphospecies criteria). Before publication, one can typically test one's idea against available data (that's what science is all about.) If the authors had done that, they would have discovered that there are NO Cretaceous primates, in fact, the first primate is now agreed to be around 55 Ma. If data conflict with ideas, however well founded (and this one is not), then the ideas have failed the test and you start again. This is another example of a peculiar mind-set, centered in Chicago and Santa Barbara, which accepts all species as identical blobs, ignores biology, and uses mathematical models and simulations to arrive at extraordinary "insights" and "discoveries" that have no basis in real-world biology or paleontology.
