Why symmetry
Sorry, maybe every point is already mentioned, but I've four things why symmetry can exist in combination with evolution:
  • If a mutation for the left side is selected for, the same mutation for the right side is probably also beneficial.
  • Genetic material probably codes for both sides of the body at the same time.
  • Not only for our swimming ancestors, but also for our flying companions and for us - walking - will symmetry easify movements.
  • To keep balance.
