Re: How did consciousness evolve?
Your worldview simply cannot ground emotions like love in anything that is not reducible to "blind" gene survival.
The article added some additions to it: consciousness arose to handle sensory overload. That's basically it
. There is nothing profound there for you; propagation and survival of genes within organic vessels that negotiate sensory overload via consciousness.
Your love for your family and friends is your subjective experience and THAT'S it, but it has no objective meaning to blind and purposeless Nature.
Why do you have to be so entirely dishonest about your worldview?
It's really old.
