Who would have thought that life would originate at the bottom and then aggregate in complexity upward as time went by? There is this very common form of thinking that so many of us have that things are ordered from the top down. Our understanding of evolution takes this kind of simple, common-sensical thinking and flips it. Common sense is not a very reliable guide in science. Common sense, for instance, doesn't bring us to this notion that on a quantum level, there is this exorbitant amount of open space in a dense object such as lead. We have a very limited threshold of perception and we make comparisons. We filter everything through our constrained threshold.
I find evolution to be a thrilling idea. There is this grand unification, this beautiful nexus between all DNA expressions.
