Mitochondrial Eve

In class we have been discussing Mitochondrial Eve. Mitochondria is the DNA that everyone has that looks exactly like theirs mothers. The only time our Mito. DNA doesn't match our moms is if there has been some sort of genetic mutation. The idea of Mitochondrial Eve, is that if we trace back our Mit. DNA we will all be linked back to one specific woman. This shows that as humans we are all somehow linked to one another. Also, many believe that the reason we are all spread out and look different is because at one point in time groups of people left and moved in different directions across the globe. Once this occurred, people began to develop traits that help them live in their environment better. Some people developed darker skin because they needed it to protect them from the suns intense rays. Others loss this skin function because they no longer needed it where they live. 

This is a map of where different people have have left.

This picture is supposed to represent Mitochondrial Eve.
