Evolution has forced innovative solutions to biomolecular problems. Some may inform the growing field of nanotechnology

Engineers attempting to build atomic-scale machines often start with the methods and materials for building full-scale machines and then miniaturize them. David Goodsell, however, reminds readers that nature solved the problem of small machines three billion years ago, with the emergence of first cells and biomolecules. The innovative solutions wrought by evolution, says the author, may well serve as a guide in the construction of artifical nano-machines.
