One of the 20th century's leading evolutionary Biologists. His work contributed to the conceptual revolution that led to the synthesis of Mendelian genetics and Darwinian evolution, and to the development of the Biological Species Concept.

Furthermore, his writings reflect, not only a technical expertise in biological subjects, but a broad and penetrating understanding of the deeper philosophical issues involved.
