Evolutionary biotechnology applies the principles of molecular evoluti
on to biotechnology, leading to novel techniques for the creation of b
iomolecules with a great variety of functions for technical and medica
l purposes. Several basic principles for the application of evolutiona
ry strategies can be derived from a comprehensive theory of molecular
evolution. Prerequisites for evolutionary biotechnology are summarized
with respect to the different classes of biomolecules and a few, sele
cted applications are described in detail. Concepts for the technical
implementation of evolutionary strategies are presented which allow au
tomatized, high throughput processes. (C) 1997 Published by Elsevier S
