Article of the Week

I thought that this article was very interesting because of the pigment variation in different people. I liked when it talked about how the variation between brown and green eyes could be explained with the amount of melanin produced, and how it explained the cause of blue eyes so clearly. I also liked how the article told that blue eyes were a useless mutation that had no effect on survival of the human species.
In fact, one quote that interested me was this; as Professor Eiberg says, "it simply shows that nature is constantly shuffling the human genome, creating a genetic cocktail of human chromosomes and trying out different changes as it does so." This provokes my interest in human nature and how it affects so many other things that surround it. A second quote derives a conclusion from the melanin variation in blue-eyed people; "From this we can conclude that all blue-eyed individuals are linked to the same ancestor," says Professor Eiberg. "They have all inherited the same switch at exactly the same spot in their DNA."
This last quote leaves me with two questions in particular, how can a scientific conclusion be drawn from so little information, and what can we use this discovery to accomplish?
