It depends on what we are arguing about. Surely paleoecology is the
discipline which should have the right-of-way here--I mean whether or not
a bolide was significantly implicated in the extinction of the dinosaurs.
In this respect, the iridium signature and its global distribution--i.e.,
Dr. Alvarez' area of expertise--may be totally irrelevant. Indeed, there
_is_ no data relating this event to dinosaur extinction. So, depending on
his or her ecological training, the Times reviewer may have more informed
opinions than an astrophysisist.
