W. Ford Doolittle FRSC FRS (born February 21, 1942, in Urbana, Illinois)[1] is an evolutionary and molecular biologist.

Because of his philosophical musings on the non-existence of an all-encompassing Tree of life, Doolittle has occasionally been cited on Intelligent Design blogs.

However, though Doolittle argues that a bifurcating tree is not an adequate metaphor for the evolution of life on earth, he is not a supporter of Intelligent Design.

A single common ancestor and tree relating all of life on earth is not a necessary component of the theory of descent with modification, the essence of evolution.

In addition to his contributions to evolutionary biology, Doolittle is an artist who studied at NSCAD University, achieving a BA in photography.
