You are infact correct, the san( kalahari bushmen) do have the eye fold as do many other people who live in light intensive environments, like
deserts and the arctic.

----Thread Update----
Ancient Mesoamerican peoples manufactured rubber from latex some 3,500 years before the modern invention of vulcanization and even compounded it for different applications, says new research from a Massachusetts Institute of Technology research team.
According to archaeology professor Dorothy Hosler and technical instructor Michael Tarkanian of MIT’s Department of Materials Science and Engineering, pre-Hispanic peoples not only invented rubber, but they perfected a system of chemical processing to enhance rubber’s properties.
The result was strong, wear-resistant rubber for sandal soles, resilient, bouncy rubber for game balls, and rubber optimized for resilience and strength for wide bands used to attach handles to axe heads.
The research follows a 1999 study which demonstrated that these people predated development of Charles Goodyear’s vulcanization process by 3,500 years

I think you hit the nail on the head.
My take on things...
The earth's continents where once all joined, countless millions of years ago.
How we got here is lost to the past but needless to say an advanced people lived in great cities. One day the earth was struck repeatedly by asteroids. Asteroids which ran on a 15,000-25,000 year cycle of collision with our planet.
