The Naukan people are a group of people indigenous to Siberia. Based on a variety of archaeological findings, they are believed to have lived on the Chukotka Peninsula east of the Bering Sea around 2,000 years ago. Geographically, this area is extremely close to what is modern-day Alaska, despite being on a different continent. A recent study suggests that Naukan people carry “First American” DNA, that is, DNA that is found nearly exclusively in groups indigenous to North America. Thus, researchers concluded that -------Which choice most logically completes the text?the archeological evidence which places the Naukan people at Chukotka Peninsula 2,000 years ago must be false.eliminateconditions of the Chukotka Peninsula were not fit for habitation, which caused the Naukan people to migrate to Alaska.eliminateat some point, the Naukan people migrated to Alaska and intermingled with the people there, before settling in Siberia.eliminatethere were significant cultural ties and trade between Siberia and Alaska 2,000 years ago.

Modern groups that are likely to have DNA from Neanderthals

Neanderthals and humans have had a long and intertwined history. Studies of ancient DNA have shown that human and Neanderthal lineages split apart 700,000 years ago. However, fragments of Neanderthal DNA can still be found in living humans. John Capra, a geneticist at University of California San Francisco, has been researching the remaining fragments of Neanderthal genes as they relate to sleep. Capra found evidence that the age old question of whether someone is an early riser or a night owl can be answered by studying Neanderthal fragments in DNA: people who were early risers had more Neanderthal fragments in their DNA than people who preferred staying up late.Which choice best describes the function of the fourth sentence in the overall structure of the text?It makes a generalization about the presence of Neanderthal fragments in modern human DNA.eliminateIt introduces a certain study related to the general information cited earlier about the connection between human and Neanderthal DNA.eliminateIt offers a specific example of the link between sleep and fragments of Neanderthal DNA found in modern humans.eliminate It states the hypothesis investigated by geneticist John Capra and his team at the University of California San Fransisco.

While researching a topic, a student has taken the following notes:Denisovans were a close relative of both humans and Neanderthals, another early hominin that lived between 200,000 and 50,000 years ago. In a 2019 study, Katerina Douka and Thomas Higham analyzed human artifacts found in the same cave as Denisovan and Neanderthal remains. They were initially unsure if ancient humans, Denisovans, and Neanderthals all shared the cave or simply used it independently at different times. Using a combination of radiocarbon and DNA dating, they determined that the three groups likely overlapped within the cave at various times.The student wants to present the study and its findings.

While researching a topic, a student has taken the following notes:Archaeologists Dennis Stanford and Bruce A. Bradley proposed the Solutrean Hypothesis, suggesting that the first inhabitants of the Americas may have arrived from Europe, specifically during the Upper Paleolithic Solutrean period around 20,000 years ago.The hypothesis posits that ancient people, possibly from the Iberian Peninsula, migrated across the North Atlantic by boat, using the ice sheets as stepping stones to reach North America.Supporters of the Solutrean Hypothesis point to similarities in stone tool technologies found in both Solutrean Europe and Clovis culture in North America as potential evidence of this migration.The hypothesis remains contentious within the archaeological community due to a lack of direct evidence and alternative theories regarding the people of the Americas.25Mark for ReviewCross out answer choices you think are wrong.ABCThe student wants to summarize the Solutrean Hypothesis. Which choice most effectively uses relevant information from the notes to accomplish this goal?AThe Solutrean Hypothesis suggests that ancient Europeans from the Solutrean period migrated to North America using the North Atlantic as a route, citing similarities in stone tool technologies between Solutrean Europe and the Clovis culture.BArchaeologists Dennis Stanford and Bruce A. Bradley proposed the Solutrean Hypothesis, connecting the migration from Europe's Solutrean period to the peopling of the Americas.CSupporters of the Solutrean Hypothesis argue for a European migration to North America through the North Atlantic, using ice sheets as stepping stones, based on similarities in stone tool technologies.DThe Solutrean Hypothesis remains contentious within the archaeological community due to the absence of direct evidence and conflicting theories about the initial settlement of the Americas.
