Evolution is a random process.
By no means does the fact that we can type on the innerweb mean that we are "more" evolved than snails.
Random paths of evolution can lead to some pretty wacky things. It led to us, to flying squirrels, to squid, to manatees, and even to ideas (and thusly to thoughts of god....). Heavy.
Thought of the day: most of our DNA does nothing, i.e. DNA codes for everything, except only 10% of it actually codes... what is the rest of it?
I think it is our collective memories... our collective unconsciousness, encoded there, but not in a regular 3-digit codon stucture as it is for our physical structures...
