A fine copy with a touch of creasing to extremities. On the Origin of Mammals is a short article that addresses the contemporary debates on the ancestry and origins of mammalian species. Through an analysis of the paleontological evidence available at the time, Broom seeks to find support for one of two prominent theories that existed at the time. Though it was generally agreed upon that mammals were descended from the clade of amphibians known as Batrachia, scientists continued to debate whether there had existed an intermediate, reptilian stage of development in the evolution of mammals from these amphibians. Broom concludes that evidence points to the evolution of mammals from reptiles, specifically a sub-order known as the Cynodonts. Scientists today agree that mammals did indeed evolve from these large reptiles. Robert Broom was a South African zoologist and paleontologist, whose research focused primarily on the evolution of mammals, specifically hominids. Broom inscribed this particular copy to Barnum Brown, an American paleontologist. Perhaps one of the most recognizable names in paleontology, Brown was responsible for the first documented discovery of the Tyrannosaurus, popularly known as the "T-Rex."
