Scientific paper

The emergence and spreading of chirality on the early Earth is considered by
studying a set of reaction-diffusion equations based on a polymerization model.
It is found that effective mixing of the early oceans is necessary to reach the
present homochiral state. The possibility of introducing mass extinctions and
modifying the emergence rate of life is discussed.
