I'm aware of the near-symmetry preference for faces--but I wasn't necessarily talking about faces, or even exclusively about humans: I was referring to little things like, oh, even numbers of same-sized limbs, same number of digits on each extremity... Occasionally the base genome throws up minor variations on essential bilateral (or, in some simpler organisms, radial) symmetry, but even in those cases, it tends towards a single exceptional feature--I'm thinking of a lobster: basic bilateral symmetry, but with a variation in the claws.
Symmetry is everywhere. |
