For the first time, scientists have successfully obtained the genome of a man who lived 40,000 years ago in China. The man from Tianyuan Cave in Beijing becomes the oldest individual whose genome researchers have obtained in East Asia. Chinese and foreign scientists probed the sequences of the ancient man while studying the structure of ancient populations. In 2013, Fu Qiaomei, a female researcher from the Institute of Vertebrate Paleontology and Paleoanthropology under Chinese Academy of Sciences, investigated the sequences of chromosome 21. Scientists later drew other chromosomes. Fu told thepaper.cn that the Tianyuan individual's genome was not a complete set as it lacked some gene segments, but it contained the data of most sites that researchers are interested in comparing population genetics. The scientists discovered that the man's genes had more in common with ancient and present-day East and Southeast Asians than any Basal Eurasian ancestry. They also found that he shared more alleles with a 35,000-year-old European individual found in Belgium. The discovery showed that there was not a single population split between early Europeans and early Asians, Fu said. Meanwhile, scientists also discovered that the present-day East Asians do not share any direct genetic ancestry with the man, indicating the diversity of humans living in Asia 40,000 years ago. woven wristbandssilicone bracelets custom cheapsilicone fidget spinnerrubber wristbands custom cheapbatman wristbandthe wristband factorypersonalized rubber braceletswide rubber bandsblack rubber wristbands
BEIJING - China has held 6,471 officials in eight provincial-level regions accountable for environmental damage after inspections by central authorities from August to September, the Ministry of Environmental Protection said Friday.Inspectors also detained 424 people and imposed 547.6 million yuan (83.3 million US dollars) of fines following the fourth round of environmental inspections, the ministry said in a statement.The inspected regions were Jilin, Zhejiang, Shandong, Hainan, Sichuan, Tibet, Qinghai and Xinjiang.The ministry criticized a number of local governments for such problems as inadequate attention to environmental protection, poor treatment of air and water pollution, lack of environmental infrastructure and illegal land reclamation from the sea.The eight regions should submit plans to address the problems to the State Council within 30 work days and make them public, the ministry said.The inspections are part of China's campaign to fight pollution and environmental degradation as decades of growth have left the country with smog, polluted water and contaminated soil.Tackling pollution has been listed as one of "the three tough battles" that China aims to win in the next three years, according to the Central Economic Work Conference that concluded earlier this week.
