Systems engineering in biology is fantastic!
 
Out of all the possible molecules in the world, just two form the basis of life’s grand variety: DNA and RNA. They encode the stuff of every whale, ant, flower, tree and bacterium.

But scientists have now developed six alternative polymers called XNAs that can also store genetic information and evolve through natural selection. None of them are found in nature. They are part of a dawning era of “synthetic genetics”, which expands the chemistry of life in new uncharted directions.
