Cuvier and the birth of extinction

There was a mildly entertaining article in The New Yorker about the birth of paleo-zoology through the work of Georges Cuvier at the beginning of the 1800's. Anybody interested in the pre-Evolution age of biological theory should really read The Death of Adam, which is a fascinating telling of this period of science history. One must wonder what beliefs we hold today that are destined to be overturned in a similar manner.
