Once I wanted to participate on the action of National Geographic "Genographic" -this was the name, I think. Yes, I'm right and posted the address too. The sense of this project was (and is) to study DNA of most persons possible to understand where are we from.
The studies say, we all come from the same ancestors that lived in Africa about 50-200, 000 years ago, says the site. Than they began to migrate and with time different mutations happened in our DNA. So, if you study the mutations in your DNA using this project, you can know, what way did all your branch till arrived there, where you are today. It's interesting, you are right. You can participate on this project too. The price of the analyze begins from $119. Visit the site and find the today price if you are interested in.
Now with DNA study the scientists can resolve different problems. I give you some examples and hope you'll find something new for you too.
Nobody knew where were those exceptional people from.
Ancient historians had different points of view on this question. Dionysus thought, they are aboriginal from Italy, Titus Livius said, they came from North, Herodotus wrote they are from Livia, a state existed in the territory of modern Turkey till VI b.C.
DNA study of the population of Tuscany demonstrated, from all these opinions Herodotus had right. Etruscans come from Turkey. There were different groups of studies. One of them studied ... DNA of the cows. And even this study showed the same: the cows, original from this zone (Tuscany) have DNA different from all the other cows, living in Italy. Their DNA is similar to those of the cows, living in Turkey. And because the cows could come here only with persons that take them together in their travel, it shows once more, that Etruscans are originally from Turkey. (Lenta.ru)
Do you have blue or brown eyes?
If your eyes are brown, you are "original" as those that came out of Africa many thousands years ago. Because brown is original colour of human eyes.
During their migrations persons had different mutations in their DNA and one of them was the mutation of colour of the iris about 6-10,000 years ago.
“From this we can conclude that all blue-eyed individuals are linked to the same ancestor,” says Professor Eiberg. “They have all inherited the same switch at exactly the same spot in their DNA.”
Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production. (scientificblogging.com)
Poor me... My eyes have a colour that is unpossible to describe...
