Letter from Theodore Roosevelt to Douglas Dewar and Finn Frank

Letter from Theodore Roosevelt to Douglas Dewar and Finn Frank

Theodore Roosevelt finished Douglas Dewar and Frank Finn’s “delightful and illuminating book.” He sends his pamphlet, which criticizes Abbott Handerson Thayer’s “preposterous work” and uniquely examines the theory of concealing coloration. Roosevelt agrees with Dewar and Finn’s points of over-theorizing and their emphasis on experiments and first-hand field observations. Additionally, he sends his article addressing Alfred Russel Wallace’s “preposterous theory” about antelope horns. He cautiously dissects several of the authors’ points, including dark coloration’s relation to aggression and the inheritance of acquired characteristics.

Thayer is welcome to visit Roosevelt at Oyster Bay. Record contains two copies of the letter, the final one and the original with edits.
