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.

Recent research has discovered that the Neanderthal DNA makes up as much as 1-4% of the genome of present- day humans. However, scientists only had ------- hypothesis about how much those genes inform human traits until a new study out of the UK looking at gene expression in people with European descent who have the most likelihood of Neanderthal lineage.  The findings indicate that Neanderthal DNA may be responsible for several traits including some that dictate nuances of how an individual’s immune system operates or how someone’s body burns calories. Which choice completes the text with the most logical and precise word or phrase?indeterminate  eliminateconfounding eliminatemeticulous  eliminateconventional eliminate
