Hispanics are a blend of Native American Indians from all of the Americas and the Spanish and sometimes the Imported black slaves. The Native American Indians were from Asia. The Japanese and the Navajoes are more closely related to each other than to any other genetic group. I was amazed back around 1960 when I went to Cherokee, North Carolina and saw real live Indians. They looked like Asians from Mongolia. Or northern China. And a rather stunning fact is that a bunch of White People migrated east over to the land bridge and walked over to What is now Alaska along with all the other people who populated the Americas.
The Q haplogroup of Y-DNA is extremely common among the native populations of North and South America—over 90% among the Navajo, for example. It is thought to have originated in Siberia, probably in the Altai/Lake Baikal area. It is also found in very low numbers in European populations (mostly under 1% but notably higher in a few locales—7% in one town in Sicily, 14% on the island of Hvar in Croatia, etc.). One theory is that it was brought to Europe by the Huns. Among white Americans and African Americans the frequency is under 1%.
