Leslie Orgel - October 31, 2007
Leslie Orgel, head of the Chemical Evolution Laboratory at the Salk Institute, has died. Orgel pioneered the theory that RNA preceded DNA as a replicating molecule. At the time of his death his work was focused on searching for a precursor to RNA
He was also one of the first to suggest that life on Earth might have been seeded by extraterrestrials. His name is attached to Orgel’s rules:
“Whenever a spontaneous process is too slow or too inefficient a protein will evolve to speed it up or make it more efficient.”
&
“Evolution is cleverer than you are.”
