Abstract: Several aspects of mathematical astrobiology are discussed. It is argued thataround the time of the origin of life the handedness of biomolecules must haveestablished itself through an instability. Possible pathways of producing acertain handedness include mechanisms involving either autocatalysis or,alternatively, epimerization as governing effects. Concepts for establishinghereditary information are discussed in terms of the theory of hypercycles.Instabilities toward parasites and possible remedies by invoking spatial extentare reviewed. Finally, some effects of early life are discussed thatcontributed to modifying and regulating atmosphere and climate of the Earth,and that could have contributed to the highly oxidized state of its crust.
