Transitioning to Intelligent Materials
Darwin's hypothesis about chemical evolution requires that matter
have the potential for intelligent behavior, fixing within molecular
networks the diversity of structural features necessary for fitness
and survival in a changing landscape. Given the elaborate molecular
assemblies, the intricate chemical strategies, and the cooperative
molecular networks that have emerged in living systems from such
simple beginnings, it is not surprising that wide-ranging applications
have already been imagined for new materials able to emulate
such behavior [111-114]. And if our progress with biomaterial
applications provides any reference, these ideas have likely only
