Your DNA is Almost Certainly From Outer Space

Did you know that many of us have up to 4% neanderthal DNA? And that 100% of your DNA may come from outer space? No joke.

The biochemistry that defined the coding system of your DNA may have happened off-world, and perhaps even long before Earth existed.
