title: Superweak interactions and the biological time direction.
abstract: A hypothesis is proposed in qualitative terms, according to which left helical electrons in chiral molecules, and right helical electrons in oppositely chiral molecules have different internal timings. The basis of this hypothesis stems from two facts: (1) It has been observed that the decay processes caused by superweak interactions go slower if left helical electrons are produced compared to decay processes in which right helical positrons are produced. (2) The excited states of D and L molecules are not only parity transformed but time reversed pairs as well. Re-evaluation of many data makes the hypothesis likely. The significance of this hypothesis in the origin and evolution of life is apparent since life and evolution as a whole have a special time direction.
