  • BTW, for me, chirality is much the strongest evidence for common descent, especially when considered with all the basic biochemical structures and processes that are almost universal, with their rare and fascinating exceptions.

  • From the GW perspective, the solution to the original problem is that the notion of chirality gets modified on the lattice: Lattice Dirac operators satisfying the so-called GW relation (with the overlap Dirac operator being the main explicit example) break usual chiral symmetry but have instead an exact lattice-deformed version of chiral symm which can be used to decompose the action into left - and right-handed pieces as in the continuum.
