Aphomica has a very long origin for the human body before spreading to Eurasia about 60,000 bertahun-tahun lalu. Lanjut, the story of the human race goes through many different paths, some of which have been studied more thoroughly than others.
The eastern region of Eurasia is home to around 2.3 billion people today – tentang 30 percent of the world’s population. Archaeologists discover fossils and artifacts that modern humans occupied Southeast Asia for 60,000 years and East Asia for 40,000 tahun.
But there was not much left. Who were the people who first came to these areas and eventually developed agriculture? Where did the different population groups come from? Which groups ended domination and which were killed?
Ancient DNA helps answer some of these questions. By sequencing the genomes of people who have lived for thousands of years, scientists like me are starting to photograph the inhabitants of Asia.
Di 2016, she attended the Chinese Academy of Sciences and the Institute of Vertebrate Paleontology and Paleontology in Beijing. Kimmy joined Fu’s Molecular Fossil Laboratory. The Challenge We Face: Solve the history of humans in East Asia, with the help of the long-dead Allies – the ancient humans who lived in the area thousands of years ago.
Lab members extracted and sequenced ancient DNA using human remains from archaeological sites. Then Dr. Fu and I used computational genome tools to assess their DNA’s relationship to ancient and present humans.
One of our sequences came from ancient DNA extracted from the bones of the Tianyuan Man, a 40,000-year-old man discovered near the famous ancient anthropology site in western Beijing. One of the oldest modern humans to be found in East Asia, their genetic sequence marks them as the earliest ancestors of today’s Asians and Native Americans. He lived where the current capital of China indicates that the ancestors of today’s Asians had their roots in East Asia 40,000 bertahun-tahun lalu.
There is DNA in the south, two Hunters from Southeast Asia ages 8,000 untuk 4,000 years old and Malay are linked to the Huasan culture, yang, like the Tianyuan Man, shows the early ancestors of Asians and Native Americans. These two came from a completely different lineage from the Tianyuan Man, indicating that several genetically distinct populations had occupied Asia in the past.
But no human being today shares the same genetic makeup in East and Southeast Asia as the Huybayan or Tianyuan Man. Why were strains so long lost from the gene pool of people still living? Old farmers hold the key to this answer.
