Evolution of Symmetry

For me it is one of those sights I could watch for hours...the way that a flight of geese constantly shifts in shape and size...from a line to a wave, to a chevron, as different birds seem to take their turn in leading the flock.

I have no doubt that it all makes perfect sense to them as they operate on an instinctive level born though thousands of generations following the same route; guided by sun, stars, winds, ley lines, constant landmarks and who knows what else?

We certainly don't know in any certainty.

Which is just marvellous.
