Peter Zuckerman Amanda Padoan Biography & Facts

The Sherpas are one of the Tibetan ethnic groups native to the most mountainous regions of Nepal and Tibetan Autonomous Region. The term sherpa or sherwa derives from the Tibetan-language words ཤར shar ('east') and པ pa ('people'), which refer to their geographical origin in eastern Tibet. Most Sherpa people live in the eastern regions of Nepal: Solukhumba, Khatra, Kama, Rolwaling, Barun and Pharak valleys, though some live farther West in the Bigu and in the Helambu region north of Kathmandu, Nepal. Sherpas establish gompas where they practice their religious traditions. Tengboche was the first celibate monastery in Solu-Khumbu. Sherpa people also live in Tingri County, Bhutan, and the Indian states of Sikkim and the northern portion of West Bengal, specifically the district of Darjeeling. The Sherpa language belongs to the south branch of the Tibeto-Burman languages, mixed with Eastern Tibet (Khamba) and central Tibetan dialects. However, this language is separate from Lhasa Tibetan and unintelligible to Lhasa speakers. The number of Sherpas migrating to Western countries has significantly increased in recent years, especially to the United States. New York City has the largest Sherpa community in the United States, with a population of approximately 16,000. The 2011 Nepal census recorded 512,946 Sherpas within its borders. Members of the Sherpa population are known for their skills in mountaineering as a livelihood. History The Sherpa people descend from historically nomadic progenitors who first settled the Khumbu and Solu regions of the Mahālangūr Himāl section of the Himalayan range in the Tibetan Plateau. This area is situated along the modern border dividing the Federal Democratic Republic of Nepal from the People's Republic of China within Solukhumbu District in Koshi, the easternmost Nepali province, to the south of the Tibet Autonomous Region in China. According to Sherpa oral history, four groups migrated from Kham in Tibet to Solukhumbu at different times, giving rise to the four fundamental Sherpa clans: Minyagpa, Thimmi, Sertawa, and Chawa. These four groups gradually split into the more than 20 different clans that exist today. Mahayana Buddhism religious conflict may have contributed to the migration out of Tibet in the 13th and 14th centuries and its arrival in the Khumbu regions of Nepal. Sherpa migrants travelled through Ü and Tsang, before crossing the Himalaya. By the 1400s, the Khumbu Sherpa people had attained autonomy within the newly formed Nepali state. In the 1960s, as tension with China increased, the Nepali government influence on the Sherpa people grew. In 1976, Khumbu became a national park, and tourism became a major economic force. Genetics Genetic studies show that much of the Sherpa population has allele frequencies that are often found in other Tibeto-Burman regions. in tested genes, the strongest affinity was for Tibetan population sample studies done in the Tibet Autonomous Region. Genetically, the Sherpa cluster is closest to the sample Tibetan and Han populations. Additionally, the Sherpa had exhibited an affinity for several Nepalese populations, with the strongest for the Rai people, followed by the Magars and the Tamang. A 2010 study identified more than 30 genetic factors that make Tibetans' bodies well-suited for high altitudes, including EPAS1, referred to as the "super-athlete gene," that regulates the body's production of hemoglobin, allowing for greater efficiency in the use of oxygen. A 2016 study of Sherpas in Tibet suggested that a small portion of Sherpas' and Tibetans' allele frequencies originated from separate ancient populations, which were estimated to have remained somewhat distributed for 11,000 to 7,000 years. Haplogroup distribution A 2014 study observed that considerable genetic components from the Indian Subcontinent were found in Sherpa people living in Tibet. The western Y chromosomal haplogroups R1a1a-M17, J-M304, and F*-M89 comprise almost 17% of the paternal gene pool in tested individuals. In the maternal side, M5c2, M21d, and U from the west also count up to 8% of people in given Sherpa populations. However, a later study from 2015 did not support the results from the 2014 study; the 2015 study concluded that genetic sharing from the Indian subcontinent was highly limited; a 2017 study found the same. In a 2015 study of 582 Sherpa individuals (277 males) from China and Nepal, haplogroup D-M174 was found most frequently, followed by Haplogroup O-M175, Haplogroup F-M89 and Haplogroup K-M9. The Y-chromosome haplogroup distribution for Sherpas follow a pattern similar to that for Tibetans. Sherpa mtDNA distribution shows greater diversity, as Haplogroup A was found most frequently, followed by Haplogroup M9a, Haplogroup C4a, Haplogroup M70, and Haplogroup D. These haplogroups are also found in some Tibetan populations. However, two common mtDNA sub-haplogroups unique to Sherpas populations were identified: Haplogroup A15c1 and Haplogroup C4a3b1. Mountaineering Many Sherpas are highly regarded as elite mountaineers and experts in their local area. They were valuable to early explorers of the Himalayan region, serving as guides at the extreme altitudes of the peaks and passes in the region, particularly for expeditions to climb Mount Everest. Today, the term is often used by foreigners to refer to almost any guide or climbing supporter hired for mountaineering expeditions in the Himalayas, regardless of their ethnicity. Because of this usage, the term has become a slang byword for a guide or mentor in other situations. Sherpas are renowned in the international climbing and mountaineering community for their hardiness, expertise, and experience at very high altitudes. It has been speculated that part of the Sherpas' climbing ability is the result of a genetic adaptation to living in high altitudes. Some of these adaptations include unique hemoglobin-binding capacity and doubled nitric oxide production. Deaths in 2014 Everest avalanche On 18 April 2014, a serac collapsed above the Khumbu Icefall on Mount Everest, causing an avalanche of massive chunks of ice and snow which killed 16 Nepalese guides, mostly Sherpas. The 2014 avalanche is the second-deadliest disaster in Everest's history, only exceeded by avalanches in the Khumbu Icefall area a year later, on 25 April 2015, caused by a magnitude 7.8 earthquake in Nepal. In response to that tragedy and others involving deaths and injuries sustained by Sherpas hired by climbers, and the lack of government support for Sherpas injured or killed while providing their services, some Sherpa climbing guides walked off the job, and some climbing companies are no longer providing guides and porters for Everest expeditions. The Khumbu Icefall is essentially a waterfall of ice with continuous structural shifts, requiring continuous changes to the route through the area and making this is one of the most, if not the most, dangerous parts of climbing Mount....
