Exempel på hur man kan använda DENISOVANS i en mening

• These paintings were often created by Homo sapiens, but also Denisovans and Neanderthals; other species in the same Homo genus.
• Neanderthals and other hominins, such as Denisovans, may have contributed up to 6% of their genome to present-day non-sub-Saharan African humans.
• Within the tradition of evolutionary anthropology and related disciplines, it has been argued that the development of these modern behavioral traits, in combination with the climatic conditions of the Last Glacial Period and Last Glacial Maximum causing population bottlenecks, contributed to the evolutionary success of Homo sapiens worldwide relative to Neanderthals, Denisovans, and other archaic humans.
• The whole genome sequencing and analysis of the HGDP was published in 2020, creating a comprehensive resource of genetic variation from underrepresented human populations and illuminating patterns of genetic variation, demographic history and introgression of modern humans with Neanderthals and Denisovans.
• In 2016, the project found that Neanderthals bred with modern humans multiple times, and that Neanderthals interbred with Denisovans only once, as evidenced in the genome of modern-day Melanesians.
• There is evidence that introgression is a ubiquitous phenomenon in plants and animals, even in humans, where genetic material from Neanderthals and Denisovans is responsible for much of the immune genes in non-African populations.
• heidelbergensis, Neanderthals and Denisovans expanded north beyond the 50th parallel (Eartham Pit, Boxgrove 500kya, Swanscombe Heritage Park 400kya, Denisova Cave 50 kya).
• In 2021, researchers reported that brain organoids created with stem cells into which they reintroduced the archaic gene variant NOVA1 present in Neanderthals and Denisovans via CRISPR-Cas9 shows that it has a major impact on neurodevelopment and that such genetic mutations during the evolution of the human brain underlie traits that separate modern humans from extinct Homo species.
• Denisovans apparently interbred with modern humans, with a high percentage (roughly 5%) occurring in Melanesians, Aboriginal Australians, and Filipino Negritos.
• Further analysis revealed the Denisovans were related to the Neanderthals and interbred with the ancestors of modern Melanesians.
• It is estimated that 4% to 6% of the genome in Melanesians derives from Denisovans, while no Eurasians or Africans displayed contributions of the Denisovan genes.
• USR1 shows additional genetic affinity for Denisovans that is not matched by modern Native Americans; this additional Denisovan affinity is likely due to sampling variation from an ancient population with higher levels of heterogenous Denisovan admixture.
• Denisovan DNA is found in modern humans across Asia and Australasia, but Zhang's work connecting the Xiahe mandible to the Denisovans is the first evidence that Denisovans lived anywhere but in the Denisova Cave area.
• Researchers report that brain organoids created with stem cells into which they reintroduced the archaic gene variant NOVA1 present in Neanderthals and Denisovans via CRISPR-Cas9 shows that it has a major impact on neurodevelopment and that such genetic mutations during the evolution of the human brain underlie traits that separate modern humans from extinct Homo species.
• longi is most closely related to and possibly the same species as the Xiahe mandible from Tibet, which has been grouped with the enigmatic Denisovans, an archaic human lineage apparently dispersed across East Asia during the Middle and Late Pleistocene currently identifiable from only a genetic signature.
• It also suggests that modern humans and Denisovans met and interbred at Wallacea, and possibly in Sulawesi.
