Fascinating article. What Im gathering from reading it is that the micorbes did not have arsenic as one of the building blocks of their DNA but rather after being exposed to it began to utilize it as a building block, in the DNA backbone. DNA has two building blocks in the backbone - deoxyribose sugar and phosphate and the bases that make up the 'rungs' of the ladder of the DNA are adeine, guanine, thyamine and cytosine (for those of you that said there are only two bases or its all carbon based or whatever previoulsy). Anyhow, This would support the theory of natural selection and evolution as those best adapted to their new and arsenic ridden environment were best able to pass on their genes to the next generation and survive.
Evolution is not soemthing you believe in or dont believe in. It is a scientific theory. You either accept the scientific evidence for evolution or you reject it, there is no belief involved, its not a belief system like religion is.
