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.
TENSIONS: The Chinese aircraft and vessels were headed toward the western Pacific to take part in a joint air and sea military exercise, the Ministry of National Defense said A relatively large number of Chinese military aircraft and vessels were detected in Taiwan’s vicinity yesterday morning, apparently en route to a Chinese military exercise in the western Pacific, the Ministry of National Defense (MND) said. In a statement, the ministry said 36 Chinese People’s Liberation Army (PLA) aircraft, including J-16 fighters and nuclear-capable H-6 bombers, crossed the median line of the Taiwan Strait or an extension of it, and were detected in the southern and southeastern parts of Taiwan’s air defense identification zone (ADIZ) from 5:20am to 9:30am yesterday. They were headed toward the western Pacific to take part in a
Honor guards are to stop performing changing of the guard ceremonies around a statue of Chiang Kai-shek (蔣介石) to avoid “worshiping authoritarianism,” the Ministry of Culture said yesterday. The fate of the bronze statue has long been the subject of fierce and polarizing debate in Taiwan, which has transformed from an autocracy under Chiang into one of Asia’s most vibrant democracies. The changing of the guard each hour at the Chiang Kai-shek Memorial Hall in Taipei is a major tourist attraction, but starting from 9am on Monday, the ceremony is to be moved outdoors to Democracy Boulevard, outside the eponymous blue-and-white memorial
The Chinese Nationalist Party (KMT) supports peaceful unification with China, and President William Lai (賴清德) is “a bit naive” for being a “practical worker for Taiwanese independence,” former president Ma Ying-jeou (馬英九) said in an interview published yesterday. Asked about whether the KMT is on the same page as the Democratic Progressive Party (DPP) and the Taiwan People’s Party (TPP) on the issue of Taiwanese independence or unification with China, Ma told the Malaysian Chinese-language newspaper Sin Chew Daily that they are not. While the KMT supports peaceful unification and is against unification by force, the DPP opposes unification as such and
CASES SLOWING: Although weekly COVID-19 cases are rising, the growth rate has been falling, from 90 percent to 30 percent, 14 percent and 6 percent, the CDC said COVID-19 hospitalizations last week rose 6 percent to 987, while deaths soared 55 percent to 99, the Centers for Disease Control (CDC) said yesterday, adding that the recent wave of infections would likely peak this week. People aged 65 or older accounted for 79 percent of the hospitalizations and 90 percent of the deaths, the majority of whom have or had underlying health conditions, CDC data showed. The youngest hospitalized case last week was a six-month-old, who was born preterm and was unvaccinated, CDC physician Lin Yung-ching (林詠青) said. The infant had a fever, coughing and a runny nose early this month, but
