More details have emerged about the techniques used by University of Auckland researchers in a recent study whose results backed earlier findings that Pacific settlers originated from Taiwan, traveling down south to the Philippines and on to Hawaii around 5,000 years ago.
Geneticists, biologists and linguists teamed up to provide further evidence that unravels one of the great mysteries of human migration. In a paper published this month in the journal Science, the researchers wrote of the fantastic sea voyages aboard primitive sailing craft from Taiwan.
The evidence came in large part from the DNA of Helicobacter pylori, a parasite that lives in the human gastrointestinal tract.
Molecular biologist Mark Achtman said that H. pylori was well established in the human gut when the first people left Africa about 60,000 years ago.
As each small band of explorers left the main group to go its own way — over periods of thousands of years — the DNA of H. pylori developed tiny changes that were passed from generation to generation, leaving their own distinct pattern of genetic mutation.
By taking gastric biopsies and mucus samples from the modern day Aborigines of Taiwan, the scientists found that their particular strain of H. pylori DNA came from what is known as the hspMaori family.
The researchers were able to trace and follow the exact same strain of DNA right through the peoples of the South Pacific, proving that the migration originated in Taiwan.
Peoples with another strain of H. pylori DNA — known as hpSahul — populated New Guinea and Australia more than 30,000 years ago from uncertain origins.
“Our results lend support for two distinct waves of migration into the Pacific. First, early migration to New Guinea and Australia accompanied by hpSahul and second, a much later dispersal of hspMaori from Taiwan through the Pacific by the Malayo-Polynesian-speaking Lapita culture,” the report said.
Among the scientists directly involved in the studies was Wu Jeng-yih (吳政毅) of Kaohsiung Medical University.
Three batches of banana sauce imported from the Philippines were intercepted at the border after they were found to contain the banned industrial dye Orange G, the Food and Drug Administration (FDA) said yesterday. From today through Sept. 2 next year, all seasoning sauces from the Philippines are to be subject to the FDA’s strictest border inspection, meaning 100 percent testing for illegal dyes before entry is allowed, it said in a statement. Orange G is an industrial coloring agent that is not permitted for food use in Taiwan or internationally, said Cheng Wei-chih (鄭維智), head of the FDA’s Northern Center for
LOOKING NORTH: The base would enhance the military’s awareness of activities in the Bashi Channel, which China Coast Guard ships have been frequenting, an expert said The Philippine Navy on Thursday last week inaugurated a forward operating base in the country’s northern most province of Batanes, which at 185km from Taiwan would be strategically important in a military conflict in the Taiwan Strait. The Philippine Daily Inquirer quoted Northern Luzon Command Commander Lieutenant General Fernyl Buca as saying that the base in Mahatao would bolster the country’s northern defenses and response capabilities. The base is also a response to the “irregular presence this month of armed” of China Coast Guard vessels frequenting the Bashi Channel in the Luzon Strait just south of Taiwan, the paper reported, citing a
A total lunar eclipse, an astronomical event often referred to as a “blood moon,” would be visible to sky watchers in Taiwan starting just before midnight on Sunday night, the Taipei Astronomical Museum said. The phenomenon is also called “blood moon” due to the reddish-orange hue it takes on as the Earth passes directly between the sun and the moon, completely blocking direct sunlight from reaching the lunar surface. The only light is refracted by the Earth’s atmosphere, and its red wavelengths are bent toward the moon, illuminating it in a dramatic crimson light. Describing the event as the most important astronomical phenomenon
UNDER PRESSURE: The report cited numerous events that have happened this year to show increased coercion from China, such as military drills and legal threats The Chinese Communist Party (CCP) aims to reinforce its “one China” principle and the idea that Taiwan belongs to the People’s Republic of China by hosting celebratory events this year for the 80th anniversary of the end of World War II, the “retrocession” of Taiwan and the establishment of the UN, the Mainland Affairs Council (MAC) said in its latest report to the Legislative Yuan. Taking advantage of the significant anniversaries, Chinese officials are attempting to assert China’s sovereignty over Taiwan through interviews with international news media and cross-strait exchange events, the report said. Beijing intends to reinforce its “one China” principle
