Ok. A ‘highland route’ and a ‘lowland coastal route’ but what does that mean?

How about a map of migration?

What, 4100 years ago it came down from the North, like Canada area? 2000 years ago it then came up from Chile?

Why would it come in from the top and later again up from the bottom? It had to cross over to get to the bottom, right?

This is confusing to me.

A torturous route of some sort — it's like a-maize.

'Highland" means following a mountain range northward, coastal means coming northward along the coast.

It did not come from the north in either case.

Good question. The nearest highlands to the American southwest are the Rocky Mountains.
