Proteins fold into their native-state conformations in milliseconds to seconds, ignoring theoretical estimates that this process should take many times the age of the universe.  Much work is directed to understanding how proteins are so much smarter than theorists, who cannot even reliably predict what the final folded states will be.  Proteins have one major advantage over theorists - proteins have been working on this problem for billions of years.  We can consider different ways in which proteins may have evolved to solve the
protein-folding problem.  Using simple theoretical models, we can show how evolutionary considerations can explain many of the observed properties of proteins such as the way proteins fold, the distribution of observed protein structures, the marginal stability of proteins, and how the evolutionary robustness of protein structures co-exists with sequence plasticity.
