GALTON'S LAW OF ANCESTRAL HEREDITY
GALTON, Francis. Average Contribution of Each Several Ancestor. London, 1897.
First edition of Galton's paper on genetics, attempting to prove his law of ancestral heredity, in the original July, 1897 issue of the Proceedings of the Royal Society in original wrappers. Though ultimately overturned by Mendelian genetics, Galton's theory—strongly influenced by his cousin Charles Darwin's belief that inheritance is conditioned by a blending mechanism—sparked contentious debate and stimulated further research into the important fields of heredity and genetics. $850.
