The Ahrensburg culture or Ahrensburgian (c.12,900 to 11,700 BP) was a late Upper Paleolithic nomadic hunter culture (or technocomplex) in north-central Europe during the Younger Dryas, the last spell of cold at the end of the Weichsel glaciation resulting in deforestation and the formation of a tundra with bushy arctic white birch and rowan.
 The most important prey was the wild reindeer.
 The earliest definite finds of arrow and bow date to this culture, though these weapons might have been invented earlier.
 The Ahrensburgian was preceded by the Hamburg and Federmesser cultures and superseded by the Maglemosian and Swiderian cultures.
 Ahrensburgian finds were made in southern and western Scandinavia, the North German plain and western Poland.
 The Ahrensburgian area also included vast stretches of land now at the bottom of the North and Baltic Sea, since during the Younger Dryas the coastline took a much more northern course than today.
The Pleistocene glaciations scoured the landscape clean and covered much of it in deep quaternary sediments.
 Therefore, no undisputed Early or Middle Palaeolithic sites or finds are known from Sweden.
 As far as it is currently known, the country's prehistory begins in the Allerød interstadial c. 12,000 BCE with Late Palaeolithic hunting camps of the Bromme culture at the edge of the ice in what is now the country's southernmost province.
 Shortly before the close of the Younger Dryas (c. 9,600 BCE), the west coast of Sweden (Bohuslän) was visited by hunter-gatherers from northern Germany.
 This cultural group is commonly referred to as the Ahrensburgian and were engaged in fishing and sealing along the coast of western Sweden during seasonal rounds from the Continent.
 Currently, we refer to this group as the Hensbacka culture and, in Norway, as the Fosna culture group (see: Oxford Journal Hensbacka Schmitt).
 During the late Preboreal period, colonization continued as people move towards the north-east as the ice receded.
 Archaeological, linguistic and genetic evidence suggests that they arrived first from the south-west and, in time, also from the north-east and met half-way.
Monte Verde is an archaeological site in southern Chile, located near Puerto Montt, Southern Chile, which has been dated to as early as 18,500 BP (16,500 B.C.).
 Until recently, the widely published date has been 14,800 years BP.
 This dating added to the evidence showing that the human settlement of the Americas pre-dates the Clovis culture by roughly 1000 years.
 This contradicts the previously accepted "Clovis first" model which holds that settlement of the Americas began after 13,500 BP.
 The Monte Verde findings were initially dismissed by most of the scientific community, but in recent years the evidence has become more accepted in some archaeological circles, There is as yet no consensus, and vocal "Clovis First" advocates remain.
Balangoda Man ("Homo sapiens balangodensis") refers to hominins from Sri Lanka's late Quaternary period.
 The term was initially coined to refer to anatomically modern "Homo sapiens" from sites near Balangoda that were responsible for the island's Mesolithic 'Balangoda Culture'.
 The earliest evidence of Balangoda Man from archaeological sequences at caves and other sites dates back to 38,000 BP, and from excavated skeletal remains to 30,000 BP, which is also the earliest reliably dated record of anatomically modern humans in South Asia.
 Cultural remains discovered alongside the skeletal fragments include geometric microliths dating to 28,500 BP, which together with some sites in Africa is the earliest record of such stone tools.
The Yingpu Culture () was a late Neolithic (3500 BP - 2000 BP) culture centered on the central-west region of Taiwan.
 It was roughly distributed in the Taichung City, Changhua County, and Nantou County, especially in the mid-down streams of the Choshui River, Tatu River, and Tachia River.
The Fosna/Hensbacka (c. 8300 BCE – 7300 BCE, or 12000 cal BP – 10500 cal BP), were two very similar Late Palaeolithic/early Mesolithic cultures in Scandinavia, and are often subsumed under the name Fosna–Hensbacka culture.
 This complex includes the Komsa culture that, notwithstanding different types of tools, is also considered to be a part of the Fosna culture group.
 The main difference is that the Fosna/Komsa culture was distributed along the coast of Northern Norway, whereas the Hensbacka culture had a more eastern distribution along the coast of western Sweden; primarily in central Bohuslän to the north of Gothenburg.
 The Hensbacka culture evolved into the later Sandarna culture which is found along the coast of western Sweden.
The Chinchorro culture of South America was a preceramic culture that lasted from 9,000 to 3,500 years BP (7,000 to 1,500 BC).
 The people forming the Chinchorro culture were sedentary fishermen inhabiting the Pacific coastal region of current northern Chile and southern Peru.
 Presence of fresh water in the arid region on the coast facilitated human settlement in this area.
 The Chinchorro were famous for their detailed mummification and funerary practices.
 The area of the Chinchorro culture started to receive influences from the Andean Plateau around 4,000 BP, which led to the adoption of agriculture.
 Much later, it came under the influence of the Tiwanaku Empire.
Akalla Gårds Bollplan or simply Akalla BP is a football stadium in Akalla, Stockholm, Sweden and the home stadium for the football team Akropolis IF.
 Akalla BP has a total capacity of 2,000 spectators.
The Helwan Retouch was a bifacial microlithic flint-tool fabrication technology characteristic of the Early Natufian culture in the Levant, a region in the Eastern Mediterranean (12,500 BP – 11,000 BP) such as the Harifian culture.
 The decline of the Helwan Retouch was largely replaced by the "backing" technique and coincided with the emergence of microburin methods, which involved snapping bladelets on an anvil.
 Natufian lithic technology throughout the usage of the Helwan Retouch was dominated by lunate-shaped lithics, such as picks and axes and especially sickles (which were predominantly—at least 80% of the time—used for harvesting wild cereals).
The Dadiwan culture (ca. 7900–7200 BP) was a Neolithic culture located primarily in the eastern portion of Gansu and Shaanxi provinces in modern China.
 The culture takes its name from the deepest cultural layer found during the original excavation of the type site at Dadiwan.
 The remains of millet, pigs and dogs have been found in sites associated with the culture, which is itself defined by a thin-walled, cord-marked ceramic tradition sometimes referred to as Laoguantai.
 The site has continued to produce new information about the Dadiwan culture, for example, recent biogeochemical analyses reveal that dogs living at Dadiwan from 7900–4900 calBP likely consumed C4 carbon fixation plants throughout the year.
 Because all other wild animals (like deer and bear) found at the site only consumed C3 plants, it suggests that the natural year-round vegetation was dominated by C3 plants.
 The only way that dog bones would contain strong C4 signals was if they consumed a rare plant year-round.
 A likely candidate for this is millet (a C4 grass); and because millet only grows in the summer, the only way that dogs could eat it year round is if humans were feeding it to them.
 Therefore, this represents some of the earliest evidence for agricultural production (cultivation, harvesting, and storing of seed crops) in East Asia.
 The Dadiwan culture shares a variety of common features, in pottery, architecture, and economy, with the Cishan and Peiligang cultures of eastern China.
