American Indian Origin?

Question

I'm part american indian (Navajo to be precise which fed my interest)and was curious of where we came from(because I've seen people on here dicussing the matter), so i did some research and found this piece of research and want to know if it is true. Here is the piece

"We have recently been informed of DNA results of the original native peoples of Vancouver Island – the Salish people. The principal report on which I rely is that of Professor Mariana Fernandez Cobo in ‘The American Journal of Physical Anthropology’ 2002. She and her colleague’s analysed urine of the Salish Indians, the Navajo; the Guarani of the Amazon and of mainland Japan. The DNA of all four, the entire sequence CAGTTAGA is absolutely identical. This would be a coincidence of 65,536 to one. The Salish, Navajo and Guarani studied in the report can only be Japanese."

"• The Navajo have both Japanese (Professor Cobo) and Chinese (Professor Novick) DNA."
I've heard 1421 is wrong, but this is another source.

Answer 1

It sounds reasonable to me. arge-scale genetic research have proved that mankind originated from a very small group of people. Common ancestors have been discovered for the entire population of many billions inhabiting all five continents of the Earth: these are two thousand primeval hunters-gatherers who used to live in Africa more than 100,000 years ago. New data has been also obtained about the rates and directions of human beings’ prehistoric evolution, and the way the continents got inhabited.

The researchers have applied the recent achievements of molecular-biological technology which allow to concurrently analyze multiple DNA characteristics of a person. 377 DNA characteristics (markers) of the currently living nations from all the continents - 52 populations from Africa, Europe, Middle, Central and Eastern Asia, Oceania and America - were studied.

Having processed the accumulated data, the researchers came to the conclusion that all people on the Earth had originated from a small group of ancestors – their quantity not exceeding 2 thousand people.

Excerpts from their study:
“...the number of people in major territories of settlements, including Africa, was relatively small and probably underwent significant fluctuations – a lot of people died due to the limitations in food and severe living conditions. However, about 35 thousand years ago, steady growth began in the quantity of African “farmer” populations, and ten thousand years later, quantity of populations started to grow in Eurasia.

It is known that at that time in particular our ancestors started to use new technologies – they produced more sophisticated stone and bone tools. The tribes succeeded in procuring more food and in coping with unfavorable conditions - bad weather, predators. As a result, more children survived in each generation, and the quantity of people on the planet grew up continuously – thanks to achievement of the mind, the human species was winning the “evolutionary race”. It is interesting to note that the populations of hunters-gatherers of Africa, aboriginals of Oceania and American Indians do not have “DNA-signals” of quantity growth. Indeed, these groups of people remained at the level of previous primitive technologies and due to that they can only support their quantity at the minimum level, which, as thousands of years ago, varies significantly from generation to generation, depending on weather conditions, successful hunting and other “favors of gods”.

However, maybe the most important finding of the research is as follows. All of us, people of the Earth, are genetic brothers and sisters: if we are not “cousins from Adam and Eve, at least we descended from the children of the same tribe.

Answer 2

The American Indian peoples are like the Polynesians an Asian or mongol race who crossed across the bearing straight land / ice to colonise the Americas
the logic is faulty as these markers may be common to all Asians or a part of the Asian population. it seems logical and reasonable that both are descended from a northern Asian people. it doesn't follow that an Asian population went to japan then left japan and went to the Americas

Answer 3

i have heard that the native americans came from asia siberia by crossing an ice bridge thousands of years ago across the bering straits into alaska, then america

Answer 4

you guys crossed the bering land strait, thats why indians have an asian appearance
