J. Peter Gogarten / Evolution in Darwin’s Tangled Bank

In the final paragraph of The Origin of Species, Darwin contemplates a bank of land and all of the differing life forms that dwell on that bank—plants, birds, worms, etc. All of these various life forms were produced by the same set of natural laws. While the life forms are widely different from each other, they are also “dependent on each other in so complex a manner.” Dr. Gogarten will discuss the symbiotic relationships and genetic exchange between widely varying organisms.

Dr. Johann Peter Gogarten is a German-American biologist studying the early evolution of life. In Germany he studied plant physiology and membrane transport at the Universities of Tübingen and Giessen. He moved to the U.S. in 1987 as a postdoc to work at the University of California at Santa Cruz. He currently is Distinguished Professor of Molecular and Cell Biology at the University of Connecticut in Storrs, CT.

Gogarten is best known for rooting the tree of life and for his early recognition of horizontal gene transfer as an important force in microbial evolution. He was the first person to root the Tree of Life (biology) using an ancient gene duplication. His interests are the early evolution of life, horizontal gene transfer, selfish genetic elements and the evolutions of molecular parasites. Gogarten’s current focus is the evolution of homing endonuclease utilizing parasitic genetic elements (inteins) and the intertwining of selection occurring on the gene, population and the community level.

J. Peter Gogarten is a fellow of the American Academy of Microbiology and the International Society for the Study of the Origin of Life, a member of the CT Academy of Science and Engineering, and was selected as a recipient of a 2009 Fulbright scholarship.

Research in the Gogarten Lab at UCONN has been funded through the US National Science Foundation (NSF), the Israel-US Binational Science Foundation (BSF), and the National Aeronautics and Space Administration (NASA) Exobiology program.
