Don Prothero considers a conjecture proposed to explain a supposed periodicity in mass extinctions.

Bringing his trademark style to an increasingly relevant subject of concern, Prothero links the climate changes that have occurred over the past 200 million years to their effects on plants and animals, especially contrasting the extinctions that ended the Cretaceous period, which wiped out the dinosaurs, with those of the later…
