He laid the groundwork for a theory combining Darwinian evolution and Mendelian genetics by changing the the commonly held view that natural selection produced the best possible results and that changes would be slow. === ===Ukrainian-American geneticist and evolutionist whose work had a major influence on 20th-century thought and research on genetics and evolutionary theory.
