Heads, noses and eye sockets of people in China are becoming smaller and scientists have intiated research to discover the cause, state media reported.
Researchers from Institute of Vertebrate Palaeontology and Palaeoanthropology (IVPP) at the Research Centre for Chinese Frontier Archaeology under the Jilin University have found that in the last 10,000 years, the physical characteristics of Chinese people have undergone many changes.
Dr Wu Xue Jie from the IVPP said an anlaysis of skulls of 718 Chinese adult males from the New Stone Age, the Bronze Age and modern period have discoverd that the Chinese people's craniums and viscerocraniums were getting smaller, their noses and eye sockets are becoming narrower; and their skulls were becoming more rounded, People's Daily reported.
The reason people's skulls grew smaller during the Holocene epoch are not known and this will be the subject of further study.
However, Wu says he believes the changes are most likely related to climate, flow of population, production systems and lifestyle.
