Evolution of life's operating system revealed in detail

The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
“The history of the ribosome tells us about the origin of life,” said Loren Williams, a professor in the School of Chemistry and Biochemistry at the Georgia Institute of Technology. “We have worked out on a fine level of detail how the ribosome originated and evolved.”
