I read a Leonard post and think, yes he is a very spiritual person but I would like him to explain using his favourite subject, evolution, why!!
Gonnagle.
I think I have done so before, Gonners, but here goes again.
When sexual reproduction evolved, and because they had choice, some creatures began to choose one partner over another because they found something more attractive in them. It was the birth of the aesthetic sense, and love.
Inevitably, humans began to project that feeling of preference onto other things which we perceive with our evolved senses. Seeing, smelling, hearing, tasting and touching all lend themselves to preference, choosing one rather than another as 'nice'.
That, putting it very simply, is the way I see it.
