Quotes:
"Protein folding was basically allowing us to do evolution before
there was even life on our planet," says Fried. "You could have
evolution before you had biology, you could have natural selection for
the chemicals that are useful for life even before there was DNA."

This research can teach us more about the potential for microorganisms
on other planets and our own: The same amino acids that came to Earth
via meteorites can also be found in many other places in the Universe.

"The Universe seems to love amino acids," says Fried. "Maybe if we
found life on a different planet, it wouldn't be that different."
