I in particular am not a huge fan of the infographic[0] that uses the same image asset to refer to a spiral, box, sun, dots, etc... for entire continents, for all recorded history.
I would prefer to see pictures of these symbols, and their in-situ neighbors, and a corresponding symbol across a wide distance that's within at most 2-300 years.
We want to feel that language has commonalities, that people traveled long distances and times and kept some common bond. It might even make intuitive sense, if the people share cultural similarities. But it often results in linguists making motivated decisions without enough evidence, like happened with the "Altaic"[1] language family.
