As I have posted many times on this subject, I believe we misinterpret these cave and rock paintings.
I believe they were done, not by the males, but by the females.
While the males were out ‘hunting’ for game, the females were decorating their domicile.
Not only decorative wallpaper, but the paintings also served a different purpose: They were what we would call a ‘grocery list’.
The females would point to the object or animal they wanted the males to hunt for dinner!............................
My husband and I are sitting here chuckling! Very cute! :)
