Our Common Ancestor
If you look around, you see a lot of different kinds of people. We are all the same species, evolved from the same ancestors, so why do we all look so different? Our phenotypes range by our skin color, eye shape, hair color, our height, our weight and many more characteristics. In the book Journey of Man, (we watched the movie in class) Spencer Wells travels on a journey to find where the oldest people on Earth are living. I think the people of the African Rift Valley in southwestern Africa are fascinating. This is the tribe that dates back to the oldest Homo sapiens on Earth. This is where it all started. I think it's so cool to see all of the different phenotypes in one group of people. There are different eye shapes and facial structures that we associate with different races around the world. So basically, this one tribe of people looks like every race in the world. And personally I think that's pretty amazing.

Mandy,
I agree with this post, I think the history of humans' genetics is fascinating. It's amazing to think that we can all be traced back, if we look far enough, to one small group of people. I think the old indigenous tribes, such as the people of the Afrian Rift Valley that you mentioned, are amazing. The ocntrast between the way we live and they way they live is astonishing and they serve as a route of time-travel, as close as we will ever get to our ancestors. I think that the preservation of such cultures are imparative to not only history, but science.
What about the differential way modern day 'tribes' have been treated up until the understanding of our genome. And how they are still viewed, with all of our knowledge of how similar we are? The variation is there...
I found this movie very interesting when we watched it. It's fasinating to see how we are all linked together. I never actually thought about how we are all related. But I've always wanted to meet all my relitives from Ireland. But it was cool to see the changes through all the people.
