RE: The Fermi Paradox & The Great Filters #1 - The basics
I think they actually found a life form that had one of the elements in DNA replaced with arsenic. I think it was phosphorus that was replaced in this life form.
They couldnt find any arsenic in its DNA. I looked up a few articles before I posted this! But there is something strange about it since it thrives off something fatal to carbon based lifeforms. But regardless, look forward to going through the Fermi paradox and learning some new things!
