• Polynesians steering by the stars met Native Americans long before Europeans arrived
"By about 1200 C.E., Polynesians were masters of oceanic exploration, crossing the Pacific in outrigger canoes, guided by changes of wind and waves, paths of migrating birds, light from bioluminescent plankton, and the position of the stars."
A genomic study of more than 800 modern Polynesians and Native Americans suggests they made it all the way to South America.
