I've been having an interesting conversation with an American woman who is married to an Ainu man from Japan. She is an anthropologist who has an acute eye for details. That conversation is available to read here:
In our conversation we discovered that the Ainu and Hebrew alphabets are almost identical and that Ainu and Ancient Egyptian share many common words. As the Ainu originated in the Nile valley, this is not so surprising. However, I was surprised to learn that the Ainu came to North America via Finland, Greenland and Labrador!
It is also interesting that Cavalli-Sforza places the Ainu at the center of his genetic distance chart.
