History of Eurasia

Eurasia around 200 CE

The history of Eurasia is the collective history of a continental area with several distinct peripheral coastal regions:

Central Eurasia.[1]

Prehistory

Lower Paleolithic

Fossilized remains of

Homo cepranensis
, are local in nature, so the extent of human residence in Eurasia during 1,000,000 - 300,000 ybp remains a mystery.

Middle Paleolithic

450000 ybp. These would have presented any humans outside the tropics unprecedented difficulties. Indeed, fossils from this period are very few, and little can be said of human habitats in Eurasia during this period. The few finds are of Homo antecessor and Homo heidelbergensis, and Lantian Man
in China.

After this,

Sahara dried
up, forming a difficult area for peoples to cross.

The birth of the first modern humans (

Single-origin hypothesis), that is, to the coldest phase of the Riss glaciation. Remains of Aterian
culture appear in the archaeological evidence.

Population bottleneck

In the beginning of the

Upper Paleolithic revolution
began after this extreme event, the earliest finds are dated c.50000 BCE.

A divergence in genetical evidence occurs during the early phase of the glaciation. Descendants of female

CT
are the ones found among Eurasian peoples today.

Upper Paleolithic

Humans populated all of ice-free Europe during the Upper Paleolithic

The

anatomically modern humans to Eurasia beginning about 70,000 BC. Moving along the southern coast of Asia, they reached Maritime Southeast Asia
by about 65,000 years ago. The establishment of population centers in Western Asia, the Indian subcontinent and in East Asia is attested by about 50,000 years ago. The Eurasian Upper Paleolithic proper is taken after c. 45,000 years ago, with the
into Europe (Mousterian), and the expansion into the Mammoth steppe
of Northern Asia.

Migrations

Tracing back minute differences in the

Eurasian steppe. Crossing the Caucasus and the Ural Mountains were the ancestors of Samoyeds and the ancestors of Uralic peoples, developing sleds, skis and canoes. Through Kazakhstan moved the ancestors of the Indigenous Americans (dated 50000 - 40000 BCE). Eastbound (maybe through Dzungaria and the Tarim Basin went the ancestors of the northern Chinese and Koreans. It is possible that the routes taken by the Indo-European ancestors travelled across the Bosphorus. Genetic evidence suggests a number of separate migrations (1.Anatoleans 2. Tocharians, 3 Celto-Illyrians, 4.Germanic and Slav, - possibly in this order). Archaeological evidence has not been identified for a number of different groups. On historical linguistic evidence, see for example classification of Thracian. The traditional view of associating early Celts with the Hallstatt culture, and the Nordic Bronze Age with Germanic peoples. The Roman Empire spread after the first widespread use of iron outside Central Europe from the Villanovan culture area. Most likely there was trade also in these periods, e.g. with amber and salt
being major products.

Influences from northern Africa via Gibraltar and Sicilia cannot be readily discounted. Many other questions remain open, too; for example, Neanderthals were still present at this time. More genetic data is being gathered by various research programs.

Early Holocene

Primary cultural areas in Europe c.4500 BC

As the ice age ended, major environmental changes happened, such as

Holocene extinction event. At the same time Neolithic Revolution began and humans started to make pottery, began to cultivate crops and domesticated
some animal species.

Neolithic cultures in Eurasia are many, and best discussed in separate articles. Some of the articles on this subject include:

Ötzi the Iceman (dated 3300 BC) provides an important insight to Chalcolithic period in Europe. Proto-languages
of various peoples have been forming in this period, though no literal evidence can (by definition) be found. Later migrations further complicate the study of migrations in this period.
