Desktop including human skull in a glass dome and a first edition of Huxley's 1863 \Evidence as to Man's Place in Nature\". The book's famous frontis showing a skeleton series from ape to man is reflected in the glass. This US Appleton edition was the first to be published because of delays in the UK by Williams and Norgate publishers. Huxley's was the first book to focus on the issue that Darwin had consciously omitted from his 1859 Origin of Species - the question of human evolution. Huxley was not afraid of controversy, but by the time his book was written there was already some general acceptance for the thesis that man evolved from apes. Huxley had also lectured on much of this material before. In the addendum Huxley presented details of his acrimonious disagreement with Richard Owen over the structural uniqueness of the human brain. Huxley's viewpoint was proved to be correct."
