Footprints, found in New Mexico last September has changed paradigm of human migration theory and it was probably on “Kelp Highway” coastal migration.
Especially, spreading to South America from North wasn’t “Express”, but slow local or normal pace. So, it can be said that human started from A-Hokkaido, Japan and /or B-Jakutsk, northeast Siberia in around 30,000 BP by the same migration speed in American coast. Tens of paleolithic sites has found in northeast Siberia, on the other hand 701 ones in Hokkaido, northern island of Japan. http://www.sunda-wind.net/news/10401
