The Upper Paleolithic has the earliest known evidence of organized settlements, in the form of campsites, some with storage pits. Artistic work blossomed, with cave painting, petroglyphs, carvings and engravings on bone or ivory. The first evidence of human fishing is also found, from artefacts in places such as Blombos cave in South Africa. More complex social groupings emerged, supported by more varied and reliable food sources and specialized tool types. This probably contributed to increasing group identification or ethnicity.
Both Homo erectus and Neanderthals used the same crude stone tools. Archaeologist Richard G. Klein, who has worked extensively on ancient stone tools, describes the stone tool kit of archaic hominids as impossible to categorize. He argues that almost everywhere, whether Asia, Africa or Europe, before 50,000 years ago all the stone tools are much alike and unsophisticated.
Firstly among the artefacts of Africa, archeologists found they could differentiate and classify those of less than 50,000 years into many different categories, such as projectile points, engraving tools, knife blades, and drilling and piercing tools. These new stone-tool types have been described as being distinctly differentiated from each other; each tool had a specific purpose. The early modern humans who expanded into Europe, commonly referred to as the Cro-Magnons, left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler, cave paintings and Venus figurines.
The Neanderthals continued to use Mousterianstone tool technology and possibly Chatelperronian technology. These tools disappeared from the archeological record at around the same time the Neanderthals themselves disappeared from the fossil record, about 40,000 cal BP.

Settlements were often located in narrow valley bottoms, possibly associated with hunting of passing herds of animals. Some of them may have been occupied year round, though more commonly they appear to have been used seasonally; people moved between the sites to exploit different food sources at different times of the year. Hunting was important, and caribou/wild reindeer "may well be the species of single greatest importance in the entire anthropological literature on hunting."
The changes in human behavior have been attributed to changes in climate, encompassing a number of global temperature drops. These led to a worsening of the already bitter cold of the last glacial period (popularly but incorrectly called the last ice age). Such changes may have reduced the supply of usable timber and forced people to look at other materials. In addition, flint becomes brittle at low temperatures and may not have functioned as a tool.
The climate of the period in Europe saw dramatic changes, and included the Last Glacial Maximum, the coldest phase of the last glacial period, which lasted from about 26.5 to 19 kya, being coldest at the end, before a relatively rapid warming (all dates vary somewhat for different areas, and in different studies). During the Maximum, most of Northern Europe was covered by an ice-sheet, forcing human populations into the areas known as Last Glacial Maximum refugia, including modern Italy and the Balkans, parts of the Iberian Peninsula and areas around the Black Sea.
This period saw cultures such as the Solutrean in France and Spain. Human life may have continued on top of the ice sheet, but we know next to nothing about it, and very little about the human life that preceded the European glaciers. In the early part of the period, up to about 30 kya, the Mousterian Pluvial made northern Africa, including the Sahara, well-watered and with lower temperatures than today; after the end of the Pluvial the Sahara became arid.
The Last Glacial Maximum was followed by the Allerød oscillation, a warm and moist global interstadial that occurred around 13.5 to 13.8 kya. Then there was a very rapid onset, perhaps within as little as a decade, of the cold and dry Younger Dryas climate period, giving sub-arctic conditions to much of northern Europe.
The Preboreal rise in temperatures also began sharply around 10.3 kya, and by its end around 9.0 kya had brought temperatures nearly to present day levels, although the climate was wetter.
This period saw the Upper Paleolithic give way to the start of the following Mesolithic cultural period.
As the glaciers receded sea levels rose; the English Channel, Irish Sea and North Sea were land at this time, and the Black Sea a fresh-water lake. In particular the Atlantic coastline was initially far out to sea in modern terms in most areas, though the Mediterranean coastline has retreated far less, except in the north of the Adriatic and the Aegean. The rise in sea levels continued until at least 7.5 kya (5500 BC), so evidence of human activity along Europe's coasts in the Upper Paleolithic is mostly lost, though some traces have been recovered by fishing boats and marine archaeology, especially from Doggerland, the lost area beneath the North Sea.
Anatomically Modern Humans known archaeological remains in Europe and Africa, directly dated, calibrated carbon dates as of 2013.
Numerous Aboriginal stone tools were found in gravel sediments in Castlereagh, Sydney, Australia. At first when these results were new they were controversial; more recently dating of the same strata has revised and corroborated these dates.
Examples of cave art in Spain are dated from around 40,000 BP, making them the oldest examples of cave art yet discovered in Europe (see: Caves of Nerja). Scientists theorise that the paintings may have been made by Neanderthals, rather than by homo sapiens. (BBC) (Science)
Wall painting with horses, rhinoceroses and aurochs is made at Chauvet Cave, Vallon-Pont-d'Arc, Ardéche gorge, France. Discovered in December 1994.
Evidence for continued Neanderthal presence in the Iberian Peninsula at 37,000 years ago was published in 2017.
Artifacts suggests early human activity occurred at some point in Canberra, Australia. Archaeological evidence of settlement in the region includes inhabited rock shelters, rock art, burial places, camps and quarry sites, and stone tools and arrangements.

Spotted Horses, Pech Merle cave, Dordogne, France are painted. Discovered in December, 1994.
The Châtelperronian culture was located around central and south western France, and northern Spain. It appears to be derived from the Mousterian culture, and represents the period of overlap between Neanderthals and Homo sapiens. This culture lasted from approximately 45,000 BP to 40,000 BP.
The Aurignacian culture was located in Europe and south west Asia, and flourished between 43,000 and 26,000 BP. It may have been contemporary with the Périgordian (a contested grouping of the earlier Châtelperronian and later Gravettian cultures).
The Gravettian culture was located across Europe. Gravettian sites generally date between 33,000 and 20,000 BP.
The Solutrean culture was located in eastern France, Spain, and England. Solutrean artifacts have been dated c. 22,000 to 17,000 BP.
The Magdalenian culture left evidence from Portugal to Poland during the period from 17,000 to 12,000 BP.
