Again it is early days and progress will be slow but the foundation is even now tightening up.
This also tells us that my open conjecture in terms of alien lifeforms been engineered to task is not unreasonable at all. Agricultural man was designed close to the planets own life ways but still a robust jump. Yet the Alien Greys are so clearly designed for space itself and could have trouble competing on Earth. We ourselves mostly lack the robustness we would actually need..
We’ve added letters to the genetic code – and the results are amazing

The first life forms with a six-letter genetic code are already pumping out drugs and other materials that nature has never seen before
By James Mitchell Crow
MAKING a living thing is no mean feat, what with the billions of components that need putting together. Nature manages it with one molecule: deoxyribonucleic acid, better known as DNA. It is the instruction manual for building everything from songbirds to scorpions, seahorses to schoolchildren. Yet Steven Benner is unimpressed. “When you look at DNA, what you see is imperfection,” he says.
He has a point. It may be a guide to making wondrous things, but DNA uses an alphabet of only four letters. What if we could sprinkle in a few extra ones? Do that, and the variety of materials that living cells could manufacture goes through the roof. We might even use that power to meet some of our most pressing needs, not least for new medicines.
Benner and a few others have been chasing the dream of expanding the genetic alphabet for decades. Finally, one of them has succeeded in creating a life form that is not only founded on entirely novel genetic letters, but is also capable of using the instructions to assemble materials that incorporate wholly unnatural building blocks. This is life, but written with a whole new alphabet.
