A large skull meant a large brain and high intellectual capacity, and a small skull indicated a small brain and decreased intellectual capacity. Morton collected hundreds of human skulls from all over the world. By studying these skulls he claimed that each race had a separate origin.
The Mismeasure of Man is a 1981 book by paleontologist Stephen Jay Gould.The book is both a history and critique of the statistical methods and cultural motivations underlying biological determinism, the belief that "the social and economic differences between human groups—primarily races, classes, and sexes—arise from inherited, inborn distinctions and that society, in this sense, is an ...
The skull also contains multiple markers that can be used to determine sex. Specific markers on the skull include the temporal line, the eye sockets, the supraorbital ridge, [21] as well as the nuchal lines, and the mastoid process. [22] In general, male skulls tend to be larger and thicker than female skulls, and to have more pronounced ridges ...
A large skull meant a large brain and high intellectual capacity; a small skull indicated a small brain and decreased intellectual capacity. Modern science has since confirmed that there is a correlation between cranium size (measured in various ways) and intelligence as measured by IQ tests, although it is a weak correlation at about 0.2.
Other historical studies, proposing a black race–white race, intelligence–brain size difference, include those by Bean (1906), Mall (1909), Pearl (1934), and Vint (1934). Nicolás Palacios After the War of the Pacific (1879–83) there was a rise of racial and national superiority ideas among the Chilean ruling class. [ 85 ]
Lynn, longtime editor of and contributor to Mankind Quarterly, has concentrated his research in race and intelligence on gathering and tabulating data purporting to show race differences in intelligence across the world. He has also made suggestions about the political implications of his data, including the revival of older theories of eugenics.
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
The word "race", interpreted to mean an identifiable group of people who share a common descent, was introduced into English in the 16th century from the Old French rasse (1512), from Italian razza: the Oxford English Dictionary cites the earliest example around the mid-16th century and defines its early meaning as a "group of people belonging to the same family and descended from a common ...
