Chamonix, what a wonderful place to recreate and fell how hard most has been for my ancestors to travel to the Americas during an endless winter.
Human migration into the Americas
Archaeologists are perhaps all too familiar with the long debate over the pathways and timing of human migration into the Americas. Based on oxygen isotope records from deep-sea cores, during the last major stage of the Pleistocene epoch (10,000-50,000 years ago), a land bridge formed across what now is the Bering Strait. With Siberia and the Americas connected, conventional accounts suggest nomadic peoples tracked the big game herds that migrated to modern-day Alaska. From here, this group (or groups) subsequently traveled south and east across America through an ice-free corridor. A 2007 study examining the genome of indigenous people from North and South America and two Siberian groups found one unique genetic variant across all populations, suggesting Native Americans descended from a common ancestor.
