Absolute Morals and evolution

[RJT]

I (and others) say Absolute Morals don’t exist if no God. Others say they either do/can/might exist on their own. Chez, kid, M to the 6th, et al what say you to the following:

Perhaps, survival of the fitness and/or natural selection is the Moral Absolute if no God.?

If this is so, what does this entail? Does any life form have the Absolute right to destroy any “enemy” it deems fit. Are there parameters for this? Is it ok to kill or rule over other life forms simply because we can and/or choose to? Do we have a right to direct selection within our own species?

Man kills animals for food. Do we have a moral obligation to kill only for food? What about when we kill more animals than we can eat? Does this extend to plant life - all life forms?

Do we have the right to kill other life forms that do not endanger us (man)? Do we have the right to kill life forms because they endanger us? Why is it ok for Nature to select which species survives? Why can’t man decide too what species survives? Can we? We seem to direct this evolution to an extent anyway? We try to eradicate diseases. Is that “fair” to natural selection?

How “naturally selective” is evolution now that the life from of homosapiens has evolved?

Are there Absolutes for evolution - are we ignoring them? Should we ignore them if it benefits our species?

Even if this is not a Moral Absolute - how do we still answer these questions "ethically"? Should we try to at all - or is that anathema from an evolutionary point of view?
