Frank, It is called Variety. Look around you and you will see multiple types of trees, birds, people, etc.
I think we are constantly being biologically mutated all of the time by the flux of Dark Energy flowing thru us and low energy nuclear reactions it can create with regular matter. Sometimes that mutation is an advantage, sometimes a disadvantage, sometimes it just adds variety, like skin color. Disadvantage might be a cancer or disease. Advantage might be a modified gene that gives better hearing. If dark/vacuum energy flux increases through us/Earth, it will weed out the weakest thru environmental pressures, like the next ice age, or very bad biological health. This is the weak anthropic principle at work. We currently live in an era of low vacuum energy and mild climate. I think that can change quickly due to the sun or comets increasing this vacuum energy in our space. That is just my interpretation Stewart darkmattersalot.com On Fri, Feb 1, 2013 at 12:02 PM, <fznidar...@aol.com> wrote: > I have read many times about how we are evolving.
