These are images from the article Indo-European diffusion model:
They are centered on European prehistory and history, and their Eurasian connections, so the borders of cultures and peoples beyond the Urals (especially South Asia) are more inexact. Also, cultures and peoples from the Altai region and Africa are less clearly defined in the maps. The maps were drawn to illustrate certain points in the aforementioned article, thus they are diachronic illustrations of different cultures and peoples not exactly contemporary with each other, but often sequential in time, used to illustrate certain developments, e.g. the neolithic expansion of farming, or the chalcolithic expansion from Yamna. In that sense, they are not different from many maps used to illustrate cultural expansions and migrations of peoples.
Please report any errors by writing an email to email@example.com, attaching a link, map, article, or book (with pages) for reference – unless it is a clear mistake -, and I will correct them as soon as possible.
They have been drawn with Photoshop over Natural Earth raster images that are in the public domain.
