And if you don't believe me, Jim Johnson from the University of British Columbia just published a paper two months
ago in cell metabolism where he has a beautiful animal model where they can regulate the amount of insulin that the animal makes, you know, from scratch, and whatever that insulin level is, that's how much that animal gains.
But something did change about 800 million years
ago, and cyanobacteria and other minute organisms
in continental margin ecosystems got more phosphorus, the backbone of DNA and RNA, and a main actor
in cell metabolism.
