In 1944 George Simpson wrote that “knowing more and more about less and less may mean that relationships are lost and that the grand pattern and great processes of life are overlooked.” Awareness of this problem has had a strong influence on George’s career. Without giving up the studies that must precede sound generalizations, he has contributed to almost all aspects of evolutionary biology, and his writings have had a profound effect on modern ideas about the history of life.
