Harris A. Lewin,[1] an American biologist, is a professor of evolution and ecology and Robert and Rosabel Osborne Endowed Chair at the University of California, Davis.
In 2016 he returned to the faculty in the University of California, Davis Department of Evolution and Ecology and the Genome Center.
[12] Lewin was senior author of a study that revealed one of the most prolific bulls in the history of Holstein cattle breeding, Pawnee Farm Arlinda Chief, had a lethal gene mutation estimated to have caused half million spontaneous cow abortions worldwide.
[13][14][15][16] Lewin collaborated with researchers from the Institut National de la Recherche Agronomique in France for a study that used RNA-sequencing to highlight problems with gene expression in cloned cattle.
[19] At the 48th World Economic Forum Annual Meeting in Davos-Klosters, Switzerland, Lewin announced a landmark partnership between the Earth BioGenome Project and the Earth Bank of Codes to map the DNA of all the planet’s eukaryotes, some 1.5 million known species.
