The '''8th millennium BC''' spanned the years 8000 BC to 7001 BC (c. 10 ka to c. 9 ka). In chronological terms, it is the second full millennium of the current [[Holocene]] epoch and is entirely within the [[Pre-Pottery Neolithic B]] (PPNB) phase of the [[Early Neolithic]]. It is impossible to precisely date events that happened around the time of this millennium and all dates mentioned here are estimates mostly based on geological and anthropological analysis, or by radiometric dating.

==Global environment==
In the [[geologic time scale]], the first [[stage (stratigraphy)|stratigraphic stage]] of the [[Holocene]] epoch is the "[[Greenlandian]]" from about 9700 BC to the fixed date 6236 BC and so including the whole of the 8th millennium. The Greenlandian followed the [[Younger Dryas]] and essentially featured a climate shift from near-glacial to interglacial, causing glaciers to retreat and sea levels to rise.<ref name="ICC">{{cite web |url=http://www.stratigraphy.org/ICSchart/ChronostratChart2019-05.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.stratigraphy.org/ICSchart/ChronostratChart2019-05.pdf |archive-date=2022-10-09 |url-status=live |title=International Chronostratigraphic Chart |publisher=International Commission on Stratigraphy |last1=Cohen |first1=K.

During the 8th millennium, there were four [[List of Quaternary volcanic eruptions|known volcanic eruptions]] which registered magnitude 5 above on the [[Volcanic Explosivity Index]] (VEI). These were at [[Rotoma Caldera]] in [[New Zealand]]'s [[Taupō Volcanic Zone]] about 7560 BC; [[Lvinaya Past]] in the [[Kuril Islands]] about 7480 BC; [[Mount Pinatubo|Pinatubo]] on the island of [[Luzon]] in the [[Philippines]] about 7460 BC; [[Fisher Caldera]], and on [[Unimak Island]] in the [[Aleutians]] about 7420 BC<ref>{{cite web |url=https://volcano.si.edu/list_volcano_holocene.cfm |title=Holocene Volcano List |work=Global Volcanism Program |publisher=Smithsonian Institution |year=2013 |access-date=7 January 2021}}</ref> The biggest eruption was at Fisher Caldera, VEI 6, producing more than {{convert|50|km3|abbr=on}} of [[tephra]].<ref>{{cite web |url=https://volcano.si.edu/volcano.cfm?vn=373010 |title=Grímsvötn |work=Global Volcanism Program |publisher=Smithsonian Institution |year=2013 |access-date=7 January 2021}}</ref>

The date of c. 7640 BC has been theorised for the impact of [[Tollmann's hypothetical bolide]] with Earth. The hypothesis holds that there was a resultant global [[Disaster|cataclysm]] such as the legendary [[Deluge (mythology)|Universal Deluge]]. Bolides are [[asteroid]]s or [[comet]]s.<ref>{{cite journal |last1=Kristan-Tollmann |first1=E. |last2=Tollmann |first2=A. |year=1994 |title=The youngest big impact on Earth deduced from geological and historical evidence |doi=10.1111/j.1365-3121.1994.tb00656.x |journal=[[Terra Nova (journal)|Terra Nova]] |volume=6 |issue=2 |pages=209–217|bibcode=1994TeNov...6..209K}}</ref>

According to radiometric dates, the main occupation phases recognized at [[Shillourokambos]] took place between the end of the [[9th millennium BC]] and the end of this millennium, long before the [[Khirokitia]] Culture.<ref name="Like a Bull in a Chine Shop: Identity and Ideology in Neolithic Cyprus.">Le Brun, Alain.

==Population and communities==
Outside the Near East, most people around the world still lived in scattered [[hunting-gathering|hunter-gatherer]] communities which remained firmly in the [[Palaeolithic]].{{sfn|Roberts|1993|p=37}} Within the Near East, [[Neolithic]] culture and technology had become established throughout much of the [[Fertile Crescent]] by 8000 BC and was gradually spreading westward, though it is not believed to have reached Europe till about the end of this millennium. Planting and harvesting techniques were transferred through Asia Minor and across the Aegean Sea to Greece and the Balkans. The techniques were, in the main, cultivation of wheats and barleys; and domestication of sheep, goats and cattle.{{sfn|Roberts|1993|p=37}}

The [[World population estimates|world population]] was probably stable and slowly increasing. It has been estimated that there were some five million people c. 10,000 BC growing to forty million by 5000 BC and 100 million by 1600 BC. That is an average growth rate of 0.027% p.a. from the beginning of the Neolithic to the Middle Bronze Age.{{Citation needed|reason=The old citation didn't have a link to it, so this needs to be a source that talks about this.

==Fertile Crescent==
By c. 7500 BC (see map above right), important sites in or near the Fertile Crescent included [[Tell es-Sultan|Jericho]], [[Ayn Ghazal (archaeological site)|'Ain Ghazal]], [[Hula Valley|Huleh]], [[Tell Aswad]], [[Tell Abu Hureyra]], [[Tell Qaramel]], [[Tell Mureibit]], [[Jerf el Ahmar]], [[Göbekli Tepe]], [[Nevalı Çori]], [[Hacilar]], [[Çatalhöyük]], [[Hallan Çemi Tepesi]], [[Çayönü|Çayönü Tepesi]], [[Shanidar Cave|Shanidar]], [[Jarmo]], [[Zrebar Lake|Zrebar]], [[Ganj Dareh]] and [[Ali Kosh]]. Jericho in the [[Jordan Valley]] continued to be the world's most significant site through this millennium.{{sfn|Bronowski|1973|pp=64–69}} [[Çatalhöyük]] (see image) was a large [[Neolithic]] and [[Chalcolithic]] [[proto-city]] settlement in southern [[Anatolia]] which flourished from c. 7500 BC until it was abandoned c. 5700 BC.<ref name=Langer>{{cite book |title=An Encyclopedia of World History |editor-last=Langer |editor-first=William L. |edition=5th |publisher=Houghton Mifflin Company |location=Boston, MA |year=1972 |isbn=978-03-95135-92-1 |page=[https://archive.org/details/encyclopediaworl00will/page/9 9] |url-access=registration |url=https://archive.org/details/encyclopediaworl00will/page/9 }}</ref>

==Pottery and dating systems==
There was no pottery ''per se'' in the Near East at this time as the [[potter's wheel]] had not yet been invented. Rudimentary clay vessels were hand-built, often by means of [[Coiling (pottery)|coiling]], and [[Pit fired pottery|pit fired]].{{sfn|Bellwood|2004|p=384}} Dame [[Kathleen Kenyon]] was the principal archaeologist at [[Tell es-Sultan]] (ancient Jericho) and she discovered that there was no pottery there.{{sfn|Mithen|2003|p=60}}<ref name="Dever">{{cite journal |last=Dever |first=William G. |title=Kathleen Kenyon (1906–1978): A Tribute |journal=Bulletin of the American Schools of Oriental Research |volume=232 |publisher=American Schools of Oriental Research |pages=3–4 |year=1978|doi=10.1086/BASOR1356696 |s2cid=167007661 }}</ref> The vessels she found were made from stone and she reasonably surmised that others made from wood or vegetable fibres would have long since decayed.{{sfn|Mithen|2003|p=60}}<ref name="Dever"/> The first chronological pottery system had been devised by Sir [[Arthur Evans]] for his [[Bronze Age]] findings at [[Knossos]] and Kenyon used this as a benchmark for the Near East Neolithic. She divided the period into phases called [[Pre-Pottery Neolithic A]] (PPNA), from c. 10,000 BC to c. 8800 BC; [[Pre-Pottery Neolithic B]] (PPNB), which includes the entire 8th millennium, from c. 8800 BC to c. 6500 BC; and then [[Pottery Neolithic]] (PN), which had varied start-points from c. 6500 BC until the beginnings of the Bronze Age towards the end of the [[4th millennium BC|4th millennium]] (c. 3000 BC).{{sfn|Bellwood|2004|p=384}}{{sfn|Mithen|2003|p=60}}

==Agriculture in the Americas==
It was from c. 8000 BC that agriculture developed throughout the Americas, especially in modern Mexico. There were numerous [[New World crops]], as they are now termed, and domestication began with the [[potato]] and the [[cucurbita]] (squash) about this time.<ref>{{cite journal |title=A single domestication for potato based on multilocus amplified fragment length polymorphism genotyping |last=Spooner |first=D.

==Other cultural developments==
The [[Mount Sandel Mesolithic site]] in [[Ireland]] is dated to c. 7900–7600 BC. This was long thought to be the earliest human activity on the island, until the discovery of the [[Alice and Gwendoline Cave]] pushed the date back to 10,000 BC.<ref>{{cite news |url=https://www.irishtimes.com/news/environment/another-life-the-case-of-the-kneecapped-bear-1.2617890 |last=Viney |first=Michael |title=Another Life: The case of the knee-capped bear |publisher=The Irish Times Ltd |location=Dublin |date=23 April 2016 |access-date=8 January 2021}}</ref>

The date for construction of a [[Howick house|round-house]] near [[Howick, Northumberland]] is calculated c. 7600 BC by [[radiocarbon dating]].
