The first is a pattern in which closely related species differentiate in slightly different climates. b. The second is ...

Extinctions: Georges Cuvier

In the eighteenth century, Buffon and other naturalists began to introduce the idea that life might not have been fixed since creation. By the end of the 1700s, pal ...

Species Variability and Creationism

Design (ID) advocates try to challenge the evolutionary theory in theologically neutral terms, while their critics persistently describe them as “creationists” (e.g., Pennock 1999, Piggliucci 2003). Others define “creationist” in extreme terms. For example, Douglas Futuyma defines “special creation” ...
