Most scientists subscribe to the view that Homo sapiens arrived in North America less than 20,000 years ago.

The latest study raises the possibility that another hominin species, such as Neanderthals or a, somehow made it from Asia to North America before that and flourished.

“It’s such an amazing find and — if it’s genuine — it’s a game-changer.

It really does shift the ground completely,” says John Mc Nabb, a Palaeolithic archaeologist at the University of Southampton, UK.

While there is an estimation of this advance using interviews, it is not known how reliable these are and they cannot be made in remote areas.On the mainland, where beavers were present, their date of arrival was estimated using interviews and dendrochronology, and the dates obtained by both methods were compared for each site.Differences were found among the groups of respondents, according to property size, in their ability to detect changes in the environment made by beavers.Since it was determined that there is no relationship between the dates estimated through surveys and dendrochronology, it is not possible to determine how much lag there is from the time when changes in the environment are produced by beavers and the time when people notice this change.Our results indicate that this lag may not be constant among different groups of people.
