Why are some people black, others white?

Yes - it's a racial thing. :)

Forget about societal impacts, prejudices, or what we term 'racism.' The question is WHY some people are different colours.

Scientists have been asking the question as well. And it appears the lowly zebrafish may have an answer.

After all - some fish are white, some golden, some brown, yet they're all the same species. Scientists think they've isolated the gene that causes colour differences, and have tracked it back to humans as well.

I'm sure this may raise a number of future ethical quesions about race and the aforementioned societal impacts. Through genetic manipulation, will white parents be able to produce black children? Vice versa?

Personally, I default to the verse I learned in Sunday School... "Red, Yellow, Black and White... all are precious in his sight..."
