Ok, speaking as a scientist myself, I must say that xepherys is completely wrong in his statement that we have evolved protection against UV (please take a course in basic genetics) UV rays cause Thymine Dimers to form in our DNA, which prevents DNA Polymerase from being able to read the strand of DNA beyond the dimer. Our cells have developed the ability to correct Thymine dimers, but it takes time, the more dimers you create (ie. the more time you spend in the sun), the more likely you are to not be able to keep up with the damage, leading to errors in the reading of your DNA. Now some errors make no difference to protien function, however, some cause cell death. Accumulate enough errors in a single cell and it can lead to skin cancer. Please do not use a rudimentary knowledge of scientific theory to prove your own theories, and don't believe anything you read on the internet, go to scientific journals if you want real science, it is very common for journalists to completely misstate the significance of a journal article. If you would like a more detailed description of the problem, PM me and I will dig up some info out of one of my medical texts. BTW, the statements about darker skin listed above are quite true
