I was thinking about how to post my view on this subject. It is so easy to fall in to a scientific discussion on who's report is more accurate to someone else's. So I will try to make my personal opinion understandable in a rather easy way: So. There are ways of drawing lines between different people. Those lines which are based on biological differances can be classifieds as races. Now, since some obvious lines have been drawn up based on, for example, the color of the skin it seems as we do have races that are not socially constructed. However there are other lines we have drawn, body types for instance, endomorfs or mesomorfs that exists in all colors and has not been "racified". If we would do the race mapping complete we could end up with one race per person. That would lead us to have no practical use of the term "race". We need to draw the line somewhere. This line is drawn by people living in a certain time at a certain place within a certain society. Making the arbitrary line a social construct. So in my mind: The race concept between humans is a dead issue.
