This will help me keep things very basic, direct and a little bit kooky.
• Since Jews have been in Portugal for centuries, do Portuguese in Hawaii have Jewish blood?
• Are the Ainu the same people as the Jomon, the darker-featured early settlers of Japan?
• Since there are theories that the original settlers of the world were water-farers, is it possible that they are the same people who settled in Southeast Asia (specifically Taiwan), and then became the Jomon of Japan, and their descendants settled across the Pacific?
• Why do the singing harmonies of the South Pacific sound so similar to those in South Africa and nowhere else?
• How much did the Mongols of the Khan dynasty intermingle and intermarry with tribes in Central Asia and Eastern Europe?
• Is it true, according to one theory, that the original settlers of Northern Japan (Ainu of Hokkaido) came from Siberia, and those people originated from Northern Europe?
• Is it true that some of the original Native Americans have DNA that traces back to Northern Europe?
• What drove people to migrate through Siberia and over the frigid land bridge to Alaska despite sub-zero temperatures?
• There is a tribe in Thailand that shares similar DNA to Japanese. What is the connection?
• Was there any migration from North America to Hawaii in the pre-Western contact era?
Questions that have already been answered in my inquisitive study:
• Why did Samoans and Tongans have such a bitter rivalry that carried over to Hawaii when I was a kid back in the 1970s?
• What's the difference between Okinawan and Japanese names?
• Why do Okinawan dishes have much more pork than traditional Japanese dishes?
• How did Islam arrive in the Philippines?
• Why is there so much antipathy between the older East Asian people — Korea vs. Japan vs. China?
• How did beer brewing arrive in East Asia?
• Why does diabetes attack Asians, Polynesians and African-Americans at such a high rate?
There's more, of course, but this is enough for now.
