James William Valentine (born November 10, 1926 in Los Angeles , California ) is an American geologist , evolutionary biologist and paleontologist .

life and work

Valentine studied at Phillips University in Enid ( bachelor's degree in 1951) and the University of California, Los Angeles (UCLA), with a master's degree in 1954 and a doctorate in geology in 1958. He was then assistant professor and associate professor at the University of Missouri , interrupted from 1962 to 1963 as a Fulbright Scholar in Australia . In 1964 he became an associate professor and then a professor at the University of California, Davis . From 1977 to 1990 he was Professor of Geology at the University of California, Santa Barbara . Since 1990 he has been Professor of Integrative Biology at the University of California, Berkeley , where he has been Professor Emeritus from 1993. There he is associated with the Museum of Paleontology (as curator) and the Center for Integrative Genomics.

In the 1950s and 1960s, he studied marine mollusks of the Pleistocene in California and their paleoecology and biogeography. At the end of the 1960s, he developed a hierarchical approach to patterns in biodiversity, especially marine invertebrate fossils, and the influence of plate tectonics on biodiversity. From the 1970s onwards he dealt with the origin of the main tribal lines ( Phyla ) in the animal kingdom, set out in his book On the origin of Phyla 2004, and investigated (partly with Francisco Ayala ) the genetic variability of marine organisms and in 1976 raised the importance of Investigation of gene regulation for the explanation of different evolutionary speeds in paleontology. With Dobzhansky, Stebbins and Ayala he wrote a standard work on evolution.

Valentine is a member of the National Academy of Sciences , the American Academy of Arts and Sciences , the American Philosophical Society, and the American Association for the Advancement of Science . He is a fellow of the Geological Society of America. 1973/74 he was President of the Paleontological Society, whose medal he received. In 2004 he received the Lapworth Medal . He was a Guggenheim Fellow.

He has been married to Diane Mondragon since 1987 and has a son and daughter.
