This quote from Edward Robert Harrison – “hydrogen, given enough time eventually turns into humans”. How does it happen?
In: Biology
1) After the big bang, there was mostly just hydrogen, some helium and trace of other light element.
2) Stars are mostly made of hydrogen which fuel their fusion. If a star is big enough, it will fuse things until it get to iron and then explode in a supernovea. This extreme pressure and temperature fuse the hydrogen together into heavy elements that wouldn’t exist otherwise.
3) In those first generation stars, there was no heavy element, but after going supernovae they sent all those new heavy element throughout the universe. Second generation star like our sun have trace of heavy element in them, and those heavy element are what made terrestrial planets. On earth, that same heavy element were the source of life, which eventualy lead to human.
Conclusion : pretty much every atom making up a human body right now, was once part of a star that went supernovea.
