Paths From Babel: to the Pre-Columbian Andeans

Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth.
Genesis 11:9
Apparently a group from Babel halted in the Highlands and at a very early date some branched off to the coast and remained apart for a time.

"A large international team of researchers has conducted the first
in-depth, wide-scale study of the genomic history of pre-Columbian Andean civilizations such as the Moche, Wari, Tiwanaku, Nazca, and Inca.

The scientists found that groups living in the Andean highlands became genetically distinct from those that eventually came to live along the Pacific coast. The effects of this early differentiation are still seen today.
The genetic fingerprints distinguishing people living in the
highlands from those in nearby regions are remarkably ancient,” said first author Nathan Nakatsuka....the population of the north also developed distinct genetic signatures from populations that became prevalent in the south. Again, these differences can be observed today.
After that time, gene flow occurred among all regions in the Andes, although it dramatically slowed after 2,000 years ago.

There were two exceptions to the slowing of migration, and these were within the Tiwanaku and Inca populations, whose
administrative centers were largely cosmopolitan — people of diverse ancestries living side-by-side. “Archaeology shows the Inca occupied thousands of miles from Ecuador through to northern Chile — which is why when Europeans arrived they discovered a massive Inca empire, but we found close genetic relationships between individuals at the extreme edges of the empire.”
