These finds indicate the presence of humans in North America for approximately two millennia during the Last Glacial Maximum south of the migratory barrier created by the ice sheets to the north. This timing coincided with a Northern Hemispheric abrupt warming event, Dansgaard-Oeschger event 2, which drew down lake levels and allowed humans and megafauna to walk on newly exposed surfaces, creating tracks that became preserved in the geologic record. \u2014AMS\n                  <\/jats:p>","DOI":"10.1126\/science.abg7586","type":"journal-article","created":{"date-parts":[[2021,9,23]],"date-time":"2021-09-23T14:00:23Z","timestamp":1632405623000},"page":"1528-1531","source":"Crossref","is-referenced-by-count":194,"title":["Evidence of humans in North America during the Last Glacial Maximum"],"prefix":"10.1126","volume":"373","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3063-8844","authenticated-orcid":true,"given":"Matthew R.","family":"Bennett","sequence":"first","affiliation":[{"name":"Institute for Studies in Landscapes and Human Evolution, Bournemouth University, Poole, BH12 5BB, UK."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0309-7632","authenticated-orcid":true,"given":"David","family":"Bustos","sequence":"additional","affiliation":[{"name":"National Park Service, White Sands National Park, P.O.
