The Scythian-Siberian world was characterized by the Scythian triad, which are similar, yet not identical, styles of weapons, horses' bridles, and jewelry and decorative art.

[3] The Scytho-Siberian world emerged on the Eurasian Steppe at the dawn of the Iron Age in the early 1st millennium BC.

[7] Similarly the earliest examples of the animal style art which would later characterize the Scytho-Siberian cultures have been found near the upper Yenisei River and North China, dating to the 10th century BC.

In the late 1st millennium BC, peoples belonging to the Scytho-Siberian world expanded into Iran (Sakastan), India (Indo-Scythians) and the Tarim Basin.

[13] In the early centuries AD the western part of the Scytho-Siberian world came under pressure from the Goths and other Germanic peoples.

[2] Recent archeological and genetic data confirmed that Western and Eastern Scythians of the 1st millennium BC originated independently, but both formed from a combination of a Yamnaya-related ancestry component from the area of the European steppes,[14] and an East Asian-related component most closely corresponding to the modern North Siberian Nganasan people of the lower Yenesei.

[9] Among the diverse peoples of the Scytho-Siberian world, the Scythians are the most famous, due to the reports on them published by the 5th century Greek historian Herodotus.

[10] The terms Saka or Sauromates, and Scytho-Siberians, is sometimes used for the "eastern" Scythians living in Central Asia and southern Siberia respectively.

In the beginning of the 18th century, Russian explorers began uncovering Scythian finds throughout their newly acquired territories.

[27] Numerous archaeological finds have revealed that the Scythians led a warlike life: Their competition for territory must have been fierce.

[e] Skeletons of Scythian elites differ from those of modern people by their longer arms and legs, and stronger bone formation.

[32] From the Pazyryk valley, Scythian remains show a variety of hair colors, ranging from black to bright chestnut.

[36] The genetics of remains from Scythian-identified cultures show broad general patterns, among these are remarkably different histories for men and women.

[9] In a sample of Eastern Scythians from Tuva, the maternal lineages are nearly equally divided between Western and East Eurasian sources.

[27] The Scythians represent a "multitude of horse-warrior nomad" groups, which emerged from Bronze and Iron Age Central Asians (Western Steppe Herders or "Steppe_MLBA") who admixed with an East Asian-derived population represented by Khövsgöl LBA groups, giving rise to the various "Scythian cultures".

[45][9][46][47] Overall, modern Tajiks and Yaghnobis were found to display the strongest genetic continuity with the Bronze and Iron Age populations of Central Asia (Indo-Iranians).

[51] A later different Eastern influx, starting during the Middle Iron Age to post-Iron Age period, is evident in three outlier samples of the Tasmola culture (Tasmola Birlik) and one of the Pazyryk culture (Pazyryk Berel), which displayed c. 70-83% additional Ancient Northeast Asian ancestry represented by the Neolithic Devil’s Gate Cave specimen, suggesting them to be recent migrants from further East.

[11] This section lists the findings of genetic studies of the remains excavated in western Asia and eastern Europe ascribed to one of the Scythian cultures.

[52] Among the Western Scythians discovered at Rostov-on-Don, in European Russia, East Eurasian maternal haplogroups make up 37.5% of the total.

These results possibly suggest the increasing presence of East Eurasian women in Western Scythian populations, although autosomal genetic evidence is needed to confirm this observation.

[45] This section lists the findings of genetic studies of the remains excavated in central Eurasia and the eastern steppe ascribed to one of the Scythian cultures.

[27][f] Since the Middle Iron Age onwards, the Eastern Scythians received additional Northern East Asian geneflow, paralleling the emergence of Huns, which shared this newly arrived component.

[61] There is increasing evidence for a partial continuity from the eastern Scythians to the Turkic-speakers of the Altai region, as well as modern Uralic and Paleosiberian peoples.
