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.
ALIGNED THINKING: Taiwan and Japan have a mutual interest in trade, culture and engineering, and can work together for stability, Cho Jung-tai said Taiwan and Japan are two like-minded countries willing to work together to form a “safety barrier” in the Indo-Pacific region, Premier Cho Jung-tai (卓榮泰) yesterday said at the opening ceremony of the 35th Taiwan-Japan Modern Engineering and Technology Symposium in Taipei. Taiwan and Japan are close geographically and closer emotionally, he added. Citing the overflowing of a barrier lake in the Mataian River (馬太鞍溪) in September, Cho said the submersible water level sensors given by Japan during the disaster helped Taiwan monitor the lake’s water levels more accurately. Japan also provided a lot of vaccines early in the outbreak of the COVID-19 pandemic,
Kaohsiung Mayor Chen Chi-mai (陳其邁) on Monday announced light shows and themed traffic lights to welcome fans of South Korean pop group Twice to the port city. The group is to play Kaohsiung on Saturday as part of its “This Is For” world tour. It would be the group’s first performance in Taiwan since its debut 10 years ago. The all-female group consists of five South Koreans, three Japanese and Tainan’s Chou Tzu-yu (周子瑜), the first Taiwan-born and raised member of a South Korean girl group. To promote the group’s arrival, the city has been holding a series of events, including a pop-up
TEMPORAL/SPIRITUAL: Beijing’s claim that the next Buddhist leader must come from China is a heavy-handed political maneuver that will fall flat-faced, experts said China’s requirement that the Dalai Lama’s reincarnation to be born in China and approved by Beijing has drawn criticism, with experts at a forum in Taipei yesterday saying that if Beijing were to put forth its own Dalai Lama, the person would not be recognized by the Tibetan Buddhist community. The experts made a remarks at the two-day forum hosted by the Tibet Religious Foundation of His Holiness the Dalai Lama titled: “The Snow Land Forum: Finding Common Ground on Tibet.” China says it has the right to determine the Dalai Lama’s reincarnation, as it claims sovereignty over Tibet since ancient times,
Temperatures in some parts of Taiwan are expected to fall sharply to lows of 15°C later this week as seasonal northeasterly winds strengthen, the Central Weather Administration (CWA) said today. It is to be the strongest cold wave to affect northern Taiwan this autumn, while Chiayi County in the southwest and some parts of central Taiwan are likely to also see lower temperatures due to radiational cooling, which occurs under conditions of clear skies, light winds and dry weather, the CWA said. Across Taiwan, temperatures are to fall gradually this week, dropping to 15°C to 16°C in the early hours of Wednesday
