If you truly value science move over popular magazines and actually read scientific publications.

You seem to find it hard to differentiate between racial as a folk category and race as a scientific category. The racial categories that people use everyday such as black, white, Asian, etc. have little scientific validity. The concept of clines and clusters do. But the latter don’t map on to typically used racial categories. Groups bleed into each other making neat categories impossible and you can make a plethora of contradictory racial categories depending on what method you use.
