Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Leigh Maiorana Van Valen was an American evolutionary biologist. He was professor emeritus in the Department of Ecology and Evolution at the University of Chicago. Amongst other work, Van Valen's proposed "Law of Extinction" drew upon the apparent constant probability of extinction in families of related organisms, based on data compiled from existing literature on the duration of tens of thousands of genera throughout the fossil record.
