Revkin.net - Deep Roots of New Extinction Debate

[Revkin, 2000] There is a growing realization among ecologists that the endgame for species is not nearly as straightforward as it is portrayed in mathematical models. These predict extinction rates by crunching the density of species in a habitat, the size of the habitat and the rate at which it is destroyed. The discrepancy between theory and reality has led some biologists to call for a change in the way conservationists describe the extinction process to the public, and in the way that scientists study it.

A growing group of paleontologists and ecologists are calling for a new push to improve the data behind estimates and to stop making broad statements comparing current events to past cataclysmic extinction spasms like the one that erased the dinosaurs 65 million years ago. Those comparisons, they say, implied a level of clarity in the science that just does not exist.
