Before I start I would like to say that I have no intentions to discriminate or insult any cultures  I am just curious about human evolution and the reasons behind them. I am not here to say that any culture appearance is wrong or that another is better. I would like to say that although I have done research into my work I am not scientifically right I would just like to put out a few theories and ideas, feel free to comment with any of your own theories. I would like to find out why facial structure all over the world is different with theories such as Pangaea (that all continents were connected and the world was one piece of land) then surely humans should all be similar in facial structure not radically different?
