During the last Ice Age (which ended 11,700 years ago), humans moved to the Americas from Asia through what was then a land bridge to North America, according to data provided by different studies.
In this way, they would reach what is now the west coast of British Columbia, Canada, as well as the southern coastal regions.
Currently, the Pacific coast of Canada is largely covered by dense forest and can only be accessed by boat, making it difficult to search for archaeological evidence that can support this hypothesis.
A group of researchers, led by the Hakai Institute and the University of Victoria, Canada, excavated beach sediments from the intertidal zone (littoral between the maximum and minimum tides) on the coast of Calvert Island, in British Columbia, where the level of the sea was at the end of the last Ice Age two or three meters lower than today.
The scientists discovered 29 human footprints of at least three different sizes in these sediments, whose radiocarbon dating has been estimated to be around 13,000 years old.
«This find provides evidence of the sailors who inhabited this area during the end of the last ice age.«Says Duncan McLaren, lead author of the study that publishes the journal PLOS ONE.
Digital photographic measurements and analyzes revealed that the footprints probably belonged to two adults and a child, all barefoot. The work suggests that humans were present on the west coast of British Columbia some time ago. 13,000 years, during the most recent Ice Age.
Arrival of modern humans in America
This finding adds to the latest evidence to support the hypothesis that humans used a coastal route to move from Asia to North America during the last Ice Age.
The authors suggest that new excavations, with more advanced methods, are likely to discover more human footprints in the area and help rebuild early human settlement patterns on these shores.

After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news about archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
