Topic#2-From the Journey of man: The genetic Odyssey

Where are the people come from? How to know that? Which ways we can use to? Where is the first place, we live? When we moved to other country? And why we have to know about who we are?

We have to know about that because it tells me about whom we are why we are we in today. That means its very important for us to know about that.

And how we know? By analyzing DNA is the answer. DNA is shows everything about us. From analyzing the DNA of people it shows the people lived in East Africa in around 60,000 years ago- First generation of Y-chromosome [Adam]. And then the people move to Saudiabia by across the Mount of the Red Sea The gate of grief -. And take to be 2 groups of people here.

First group is move to Australia by along the way to India around 30,000 years ago. And from Sri-Lanka they continue along the India Ocean to western Indonesia then a land mass attached to Australia and from this group they across the North Pacific Ocean pass through Japan and Australia to North America [We called this group M 130 Move around 50,000 years ago]

And the another group is move to northern Saudiabia, up to the Nile and the Levant [We call this group M 89 move around 45000 years ago]

From M 89 group it takes 2 groups here first group is move to European we call this group M 172 move around 10,000 years ago.

And the bigger group is move to Middle East and take to be 3 groups again.

The smallest group moved to the south to India. The middle group is move down to Southeast Asia [M 175 35,000 years ago.] passed through china and finish at Russia [This last group call M122 10,000 years ago.]. And the last group moved ups to Russia [M45 35,000 years ago.] and takes 2 groups here, first group was moving to European [M130 30,000 years ago] and moved back to south of Russia [M17 10,000 years ago]

While the European group was moving, the another group move for a long way to Russia [M242 20,000 years ago] and across to Alaska passed through North America to South America [M3 10,000 years ago].

And The people finished to moved place in 8,000 years ago.

That means the people moved from Africa for find new place for live. And Russia is the biggest place for people because every group moved pass Russia but Russia is the second newest place The people moved to Russia around 20,000 years ago . And the newest group is America group because they move to there around 10,000 years ago, except M130 groups because they moved to America by across the ocean around 50,000 years ago. But they still use 10,000 years for moved to America Also that the fist people found America around 5,000 years ago from American history book.

Inspire of the oldest group is The Australia group because they moved around 50,000 years ago and the people born in 60,000 years ago Homo spear species. But the people that look like original man is the people in Ethiopia, Sudan and southern Africa

But at all is the history of man Adam. It isnt mean the history of people because from the history, the woman Eve show DNA around 150,000 years ago. But he focuses at men because he said "It turns out that the Y-chromosome gives us two very important clues to the question of how we populated the world. First, it shows us our most recent common ancestor (Adam). This man lived in Africa around 60,000 years ago. The significance of this date is that it means that all modern humans were living in Africa until at least that time. In other words, within the past 60,000 years - only about 2,000 generations - our species has populated the entire planet. Clearly, we are all very closely related. The second clue provided by the Y-chromosome concerns the routes we followed in our migrations around the planet. Due to something I describe in the book as 'sexual politics', the male line gives us the best view of the routes followed. So, the Y - a piece of DNA that really doesn't do much more than to make men men - is one of the best historical documents ever written"
