Charles Loring Brace IV was an American anthropologist, Professor Emeritus at the University of Michigan's Department of Anthropology and Curator Emeritus at the University's Museum of Anthropological Archaeology. He considered the attempt "to introduce a Darwinian outlook into biological anthropology" to be his greatest contribution to the field of anthropology.
In 1962, Brace published a paper in American Anthropologist titled "Refocusing on the Neanderthal Problem" where he argued, in opposition to French anthropologist Henri Vallois, that the archeological and fossil evidence did not necessarily support the idea that the Neanderthals were replaced by Cro-Magnon populations migrating into Europe, rather than being ancestral to early Homo sapiens. Brace continued his reappraisal of the Neanderthal problem in 1964 in "The Fate of the 'Classic' Neanderthals: a consideration of hominid catastrophism" published in Current Anthropology. Here Brace traced the history of research on the Neanderthals in order to show how interpretations established early in the century by Marcellin Boule and notions such as Arthur Keith's pre-sapiens theory had convinced many anthropologists that the Neanderthals played little or no role in the evolution of modern humans. Brace argued that cultural factors, especially the increased use of tools by Neanderthals, produced morphological changes that led the classic Neanderthals to evolve into modern humans. Brace remained a vigorous proponent of the idea that Neanderthals are ancestral to modern humans. He also argued that the fossil record suggests a simple evolutionary scheme whereby humans have evolved through four stages, and that these stages are somewhat arbitrary and reflect our limited knowledge of the fossil record. Brace emphasized the need to integrate the ideas of Darwinian evolution into palaeoanthropology. Much earlier research into human origins relied on non-Darwinian models of evolution; Brace presented his advocacy of the Darwinian approach in The Stages Of Human Evolution, first published in 1967. Brace's ideas generated considerable controversy, as much for his brash criticism of his colleagues as for their content, but they have also influenced a generation of anthropological research into human evolution and the interpretation of the Neanderthals.
Other studies
In the publication "Clines and clusters versus Race: a test in ancient Egypt and the case of a death on the Nile", Brace discussed the controversy concerning the race of the Ancient Egyptians. Brace argued that the "Egyptians have been in place since back in the Pleistocene and have been largely unaffected by either invasions or migrations". In a 2006 publication "The questionable contribution of the Neolithic and the Bronze Age to European craniofacial form", Brace argued that Natufian peoples, who are thought to be the source of the European Neolithic, had Sub-Saharan African admixture, but that "the interbreeding of the incoming Neolithic people with the in situ foragers diluted the Sub-Saharan traces that may have come with the Neolithic spread so that no discoverable element of that remained."
