The remains of a teenage girl, aged 15–17 at her death, and nicknamed <u>"Naia"</u>, <em><u>that are more than 12,000 years old</u></em>, were inside a flooded cave located near <em><u>Tulum, Quintana Roo in Mexico</u></em>. They were recovered in 2007 by the cavers Alejandro Álvarez, Alberto Nava and Franco Attolini, of the<em><u> Tulum Speleological Project (PET)</u></em>, dedicated to the registry of the underwater heritage of the region. After seven years of research, a multidisciplinary team from USA, Canada and Mexico, whose principal investigator of the research on <u>"Naia"</u>, <em><u>James Chatters</u></em>, an archaeologist and paleontologist, reported in 2014, that <u>"Naia</u>" has already contributed to understand the origins of the first Americans and her DNA <em><u>confirms the idea that "a single group of Asian emigrants gave rise to both the earliest American settlers and modern Native Americans"</u></em>. <u>So, right answer is B. Members from one single, genetically uniform population populated the Americas from at least 16,000 years ago.</u>
