Hāʻawi ia i ka ʻike hou aku i ke ʻano o ke kanaka
ʻO kahi niho pēpē ma kahi o 130,000 mau makahiki, i loaʻa i loko o ke ana ma Laos, hiki ke kōkua i nā ʻepekema e ʻike hou aku i ka ʻike e pili ana i kahi hoahānau mua o ka lāhui kanaka, e like me kahi noiʻi i paʻi ʻia ma Nature Communications. Manaʻo ka poʻe noiʻi ua hōʻoia ka ʻike ʻana ua noho nā Denisovans - kahi lālā i pau o ke kanaka - i nā wahi wela wela o Asia Hikina Hema.
He liʻiliʻi loa ka ʻike e pili ana i nā Denisovans, nā hoahānau o ka Neanderthals. Ua ʻike mua nā kānaka ʻepekema iā lākou i ka wā e hana ana i loko o ke ana Siberian i ka makahiki 2010 a loaʻa i ka iwi manamana lima o kahi kaikamahine no kahi hui kanaka ʻike ʻole ʻia. Ke hoʻohana wale nei i ka lepo a me ka sage i loaʻa ma Denis Cave, lawe lākou i ka genome holoʻokoʻa o ka hui.
A laila i ka makahiki 2019, ua ʻike nā mea noiʻi i kahi iwi iwi ma ka Tibetan Plateau, e hōʻike ana aia kekahi o nā ʻano i noho ma Kina. Ma waho aʻe o kēia mau mōʻalihaku laha ʻole, ʻaʻohe mea i waiho ʻia ke kanaka Denisovan ma mua o kona nalo ʻana - koe wale nō nā genes o ka DNA kanaka o kēia lā. Mahalo i ka crossbreeding me Homo sapiens, hiki ke loaʻa nā koena o ke kanaka Denisovan i nā heluna kanaka o kēia manawa ma Asia Hema a me Oceania. Loaʻa i nā ʻAborigine a me nā kānaka ma Papua New Guinea a hiki i ka ʻelima pakeneka o ka DNA o nā ʻano mea kahiko.
Ua hoʻoholo ka poʻe ʻepekema "ua hui pū ʻia nā kūpuna hou o kēia mau heluna kanaka me Denisovans ma Asia Hikina Hema," wahi a Clement Zanoli, he paleoanthropologist a me ka mea kākau kumu o ka noiʻi. Akā ʻaʻohe "hōʻike kino" o ko lākou hele ʻana ma kēia ʻāpana o ka ʻāina ʻo ʻAsia, mamao loa mai nā mauna hau o Siberia a i ʻole Tibet, kahi mea noiʻi mai ka French National Research Center i haʻi aku iā AFP.
ʻO kēia a hiki i ka hoʻomaka ʻana o kahi hui ʻepekema e aʻo i nā koena o ka Cobra Cave ma ka ʻākau hikina o Laos. Ua ʻike ka poʻe loea ana i ka wahi ma nā mauna i ka makahiki 2018 e pili ana i ke ana ʻo Tam Pa Ling, kahi i loaʻa ai nā koena o ka poʻe kahiko. Ua ʻike koke ʻia he ʻano "kanaka maʻamau" ka niho, wehewehe ʻo Zanoli. Wahi a ke aʻo ʻana, ʻo ke aʻo ʻana i nā protein kahiko e hōʻike ana he keiki ka niho, he kaikamahine paha, ma waena o 3.5 a me 8.5 mau makahiki. Ma hope o ka nānā ʻana i ke ʻano o ka niho, manaʻo ka poʻe ʻepekema ʻo Denisovan ka mea i noho i loko o ke ana 164,000 a 131,000 mau makahiki i hala.
