The first North Americans probably didn’t get there by land…

Rethink your history.

It’s long been thought that the first people to populate America thousands of years ago migrated southwards through a frosty corridor in what is now called Canada.

But a new study suggests that this chilly passage – measuring some 1,500 kilometres long – could not have sustained travellers at the time the migration took place, meaning the first Americans must have entered North America via a different route.
