The atoms of proteins move around in incredibly complicated ways, but modeling how all those moving parts fit together is vital to understanding biology. Now, thanks to a supercomputer, you can see every step of the process right here.
While it is popularly believed that evolution occurs through mutations in DNA, that's simply not true. Now scientists have more evidence that evolution functions even among proteins that have no DNA.
