Stanley Marion Garn

From Wikipedia, the free encyclopedia

Stanley Marion Garn Ph.D. (born 1922) is a professor of physical anthropology. He is a professor of anthropology at the College for Literature, Science and Arts and a Professor of Nutrition at the School of Public Health at the University of Michigan. ^[1] He joined the University of Michigan in 1968.^[2]

He studied the racial differences among human populations. He shifted his emphasis more on genetic determinants of race from cranio-facial determinants.

Garn theorizes that an ancient species of early hominid killed a mentally inferior humanoid species in China and Java due to their greater intelligence. Garn determined from skull size, symphysis size and tooth thickness that in China and Java the more intelligent hominid Sinanthropus Pithencanthropus killed off the lesser evolved Neanderthal species. He emphasized that the physical differences in the remains of these two species should be acknowledged in determining their social behavior.^[3]

In 1968 Garn joined a team of genetic anthropologists to study the racial differences of ancient populations. He focused less on cranio-facial data and more on genetic data in this study. His work looked at the amount of genes within populations to determine their racial make up. This work did not assume distinct racial forms but considered gradations of specific genes between populations.^[4]

Garn considered racial classification based on physical traits to be imprecise. He considered each physical trait to be independent of each other, making classification by the assumption that a population shares certain traits incorrect. Furthermore, he was critical about racial classifications based on physical type which seemingly elevated some physical traits to a racial status, but glossed over others. He concluded that racial classifications based on physical type can always be compartmentalized into smaller populations which share more physical traits in common. He used three gradations of racial classification which were increasingly more specific in scope: geographical, local and micro.^[5] He counted thirty-four local races in the world which were caused by genetic isolation. He believed the genetic isolation among Pacific Islanders made them form three separate races which were Micronesian, Polynesian and Melanesian. ^[6]

Garn is currently doing research on the effects of obesity and bone problems. In relation to his study on obesity, he studies over-nutrition and under-nutrition, human fat over the course of the human life cycle and the correlation between growth rate in infants and their later fat amounts. He concluded that genetics forms a major component in determing a person's tendecy for obesity, but socio-economic factors are also significant. Based on his study on age and cholesterol, he concluded that people between the ages of thirty and fifty have their serum cholesterol rise which contributes to an increase risk for coronary artery disease.^[7] In relation to bone problems, he studies skeletal development, skeletal loss, odontogenesis and dysmorphogenesis. His hypothesis is that dietary differences contribute to bone loss among individuals. ^[8]

This map shows the racial classification scheme of the anthropologist Stanley Marion Garn in his book Human Races (1961), although he considered thirty-four local subraces to exist within the nine major races.

Amerindian race Asiatic race Australian race Melanesian race Micronesian race Polynesian race Indian race African race European race
