Human migrations happened during this time with people coming in from [[Eurasia]]. From about 28 ka, there were migrations across the [[Beringia|Bering land bridge]] from [[Siberia]] to [[Alaska]]. The people became the [[Indigenous peoples of the Americas|Native Americans]]. It is believed that the original tribes subsequently moved down to Central and South America under pressure from later migrations.<ref name="BLB" />{{sfn|Teeple|2002|pp=12–13}}

In the [[North American land mammal age]] scale, the [[Rancholabrean]] spans the time from c. 240,000 years ago to c. 11,000 years ago. It is named after the [[Rancho La Brea]] fossil site in [[California]], characterised by extinct forms of [[bison]] in association with other Pleistocene species such as the [[mammoth]].<ref>A. E.

''[[Bison occidentalis]]'' and ''[[Bison antiquus]]'', an extinct subspecies of the smaller present-day bison, survived the late Pleistocene period, between about 12 and 11 [[kiloannum|ka]] ago. [[Clovis culture|Clovis]] peoples depended on these bison as their major food source. Earlier kills of camels, horses, and muskoxen found at [[Wally's beach]] were dated to 13.1–13.3 ka B.P.<ref>{{cite journal |author1=Michael R. Waters |author2=Thomas W.
