What are the main points of view on the problem of the origin of Indo-European peoples?

Scientists suggest that once the ancestors of the speakers of related languages ​​represented a single community and lived in one place. Then separate groups separated, mixed with other tribes, and differences appeared and intensified in languages.
In the scientific world, the dispute about which peoples lived in the territory of Western Asia during the period of the formation of the manufacturing economy does not subside until they. Undoubtedly, both there and in North Africa in ancient times there were tribes that gave rise to the Semitic-Hamitic languages. Many ancient peoples spoke these languages: the Egyptians, Babylonians, Assyrians.
There is a point of view that in some regions of Asia Minor tribes lived, which laid the foundation for peoples speaking Indo-European languages. Nowadays, a significant part of the world’s population uses Indo-European languages. In particular, Russian belongs to the East Slavic group of Indo-European languages.
The question of the time and place of the Indo-Europeans’ appearance has also been the subject of controversy for more than two hundred years, since the relationship of languages ​​spread over vast areas from India to Western Europe was established (hence their name). Most scholars believe that the Indo-European community began to take shape in the IV-III millennia BC, but there are opinions about an earlier period (VI-V millennium BC).
Previously, it was believed that the ancestral home of the Indo-European peoples is South Scandinavia and North Germany. Currently, this point of view has no adherents among scientists. The theory of the Balkan-Danube ancestral home of the Indo-Europeans is considered the most widespread. The version about the southern Russian ancestral homeland (Eastern Ukraine, Northern Caucasus, Volga region, Southern Urals) is also popular. Finally, an opinion is expressed about the Eastern Anatolian ancestral homeland (north of Western Asia).
