During the Early Pleistocene (2.58–0.8 Ma), archaic humans of the genus Homo originated in Africa and spread throughout Afro-Eurasia. The end of the Early Pleistocene is marked by the Mid-Pleistocene Transition , with the cyclicity of glacial cycles changing from 41,000-year cycles to asymmetric 100,000-year cycles, making the climate ...
A Paleolithic site on the Yana River, Siberia, at 71°N, lies well above the Arctic Circle and dates to 27,000 radiocarbon years before present, during glacial times. This site shows that people adapted to this harsh, high-latitude, Late Pleistocene environment much earlier than previously thought. [122]
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
Archaeologists are piecing together evidence that the earliest human settlements in North America were thousands of years before the appearance of the current Paleo-Indian time frame (before the late glacial maximum 20,000-plus years ago). [51] Evidence indicates that people were living as far east as Beringia before 30,000 BCE (32,000 BP).
Map of early human migrations based on the Out of Africa theory; figures are in thousands of years ago (kya). [1]The peopling of the Americas began when Paleolithic hunter-gatherers (Paleo-Indians) entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the ...
The oldest human skeletal remains are the 40ky old Lake Mungo remains in New South Wales, but human ornaments discovered at Devil's Lair in Western Australia have been dated to 48 kya and artifacts at Madjedbebe in Northern Territory are dated to at least 50 kya, and to 62.1 ± 2.9 ka in one 2017 study.

The species classification of archaic humans during the Middle Pleistocene has always been a controversial topic, commonly referred to as "the muddle in the middle". In mainland East Asia, the early Middle Pleistocene was home to Homo erectus — best exemplified regionally by the Peking Man — but as the age continues, the anatomy of archaic human fossils becomes highly variable, with traits ...
The most archaic human fossils from the Middle Pleistocene (780,000–125,000 years ago) [18] have been found in Europe. Remains of Homo heidelbergensis have been found as far north as the Atapuerca Mountains in Gran Dolina , Spain, and the oldest specimens can be dated from 850,000 to 200,000 years ago.
