  •  But, I think we evolve for survival of fittest. (8+ / 0-)

    Seems like a direction.

    •  That's the way nature has always done it. (7+ / 0-)

      But in some respects, already, nature 'reacts' to human factors. So it seems to me it could in chosen evolution, as well. But that is just my hypothesis. I can't prove it.

    •  Only Half the Story. Full Story Is We Diverge. (7+ / 0-)

      As circumstances gradually evolve, so do we. However, at any given moment, only some of our divergence matches the direction of gradual change.

      Periodically however, major shit happens, for which only a fraction of us happen to be randomly, without preplanning, adapted. We survive and a new order arises.

      Mammals are not more fit than dinosaurs or insects; all survive to this day. Jesus taught "Consider the dinosaurs of the air...."

      Absent discontinuities it would be survival of the fittest. In a solar system with comets, asteroids and a planet with a double core and plate tectonics however, the rule is survival of the fittest and the lucky.

    •  I should have been more clear (5+ / 0-)

      Not a chosen one, or one that has anything to do with what we want,  unless you're tinkering with the genome.  Gooserock nailed it.  Fittest, but the environment is not a constant, especially not in deep time, and we're basically pond scum whose puddle could alter very fast or go away.  

      Chickens were deliberately chosen, as they have a bit of t.rex in them, by some studies.  And now being fit is reproducing in numbers to be your dinner....you are not fitter than a bacterium, or a squirrel, except by dint of local conditions that will surely change in deep time.

      But when we hit gene hacking and eugenics level manipulation, I'm pretty sure we'll just be pushing toward each parent's vision of fit.  No more gay people, to the extent nice heterosexual folks can order up straight kids.  Minimum levels of ability.  I don't think we hack ourselves into better people, though surely into more expedient ones.  And the end result may well be a huge shrinking in variation, making even a future as giblets and gravey less likely.

      Mileage varies.  Bedtime.

      •  People have tried this sort of thing before (4+ / 0-)

        with eugenics schemes.  Yes, less was understood in those days, and the methods incredibly crude, but despite our new-found sophistication, I doubt the results of a new program to consciously improve on the human species will succeed any better than past efforts.  In fact, it will probably lead to more spectacular disasters, and then we'll got back to the old-fashioned way.
