Castle name in ink front page; Is Selection of Mutation the More Important Agency in Evolution? (The Scientific Monthly, 1916). Most are in very good condition, except as noted. "His work with hooded rats provided important evidence that evolution could occur by the action of selection on small variations in traits. Other biologists (including T. H. Huxley and William Bates) had doubted Darwin's belief in the sufficiency of small variations (acted upon by natural selection over long periods of time) to explain evolution. He realized that the traits acted upon could be multifactorial." Wikipedia An interesting group of offprints. First separate editions. In good to very good condition. * |
