Planetary Systems Biology

Darwinian theory holds that natural selection operating on randomly generated chemical structures is the only mechanism to create biomolecules that confer fitness upon their hosts. A considerable gap separates this biological truism from experimental reality, however. As Kreitman and Akashi (1995) noted a decade ago, making the connection between molecular behavior and fitness has proven to be remarkably difficult.
