What is How Did Dogs Get To The Americas? An Ancient Bone Fragment Holds Clues about?

This timing coincides with when humans may have migrated into North America along a coastal route through Southeast Alaska, providing evidence that dogs and humans first entered the Americas via this coastal route rather than an interior ice-free corridor.
