Linguistic Archaeology: And here we have More Atlantic crossing evidence

 

So... not only do we have the Pre Toltec/Aztec T-group migrating across the Atlantic to become the pre-Tswana, we have a pre-Mayan (A 46%) migration across the Atlantic to the ivory coast, formation of the Fante (A/U 45%), and a return to the Americas to become Olmecs (U 37%).

In case you dont know:

• Pre-Mayan (must be before 2500BCE pre-Fante)
• Pre-Fante (must be before 2500BCE pre-Olmecs)
• Pre-Olmecs (before 2500BCE)

So we are looking at 3000BCE-2500BCE pre-Mayans crossing the Atlantic, becoming pre-Fante before 2500BCE, and returning to become pre-Olmecs at before 2500BCE. That is sea travel across the Atlantic between the time of the first egyptian Pharoah and construction of the First Pyramids of Egypt.
