What good is DNA without a ribosome? Considering how the ribosome has changed over the last 4 billion years gives insight to the crucial nature of its role in biology, the unity of all life, and the process of evolution.
In the new study, Williams and Research Scientist Anton Petrov compared three-dimensional structures of ribosomes from a variety of species of varying biological complexity, including humans, yeast, bacteria and archaea. The researchers found distinct fingerprints in the ribosomes where new structures were added to the ribosomal surface without altering the pre-existing ribosomal core from the last universal common ancestor.
