Based on MRI comparisons of 115 skulls from Koreans born in the 1930s and 1970s, the latter surpasses the former in terms of volume by about 6 percent.

Based on MRI comparisons of 115 skulls from Koreans born in the 1930s and 1970s, the latter surpasses the former in terms of volume by about 6 percent. 

Differences in the shapes of the skulls were also detected. The study proved that not only geographical and environmental causes but also social and economic changes brought about changes in the size and shape of people’s skulls. 

The results of the study were published in the latest issue of the American Journal of Physiological Anthropology, an international journal of anthropology.
