NASA discovers unique new life form

But it is not an example of evolution because the phosphate groups in question are the ones responsible for the phosphate-sugar covalent bond that forms the backbone to the DNA molecule. Evolution requires a DNA molecule in order to inflict change. It is assumed that DeoxyriboNucleic Acid contains three core elements: (1) deoxyribose sugar, phosphate head, and nucleic base. This assumption has driven the basic molecular biological assumption behind evolution.

So it's an outlier. there's plenty of other examples in science.
