@alberto:
this doesnt work like that. you are twisting situations to your needs and add values that fit your needs.
based on your theory always group b or c are "good" ones to survive.
the problem starts if you compare a t rex hunting for chickens. The defense or care wont help the chickens at all. they will have to evolve defensive patterns to be able to survive long enough (it not about winning the war).
if chickens are so hard to catch that any t rex will run his lill ass of to get one or two a day and he needs more then that, this prey will be "unefficient" for him and therefor not on his list.
so, running away, hiding, playing dead and so on are the most efficient patterns to survive and most animals will act like that.
unless the breed gets his hands on a new defensive pattern.
humans with a gun can defend themselfs from a trex. humans without a gun should run and hide.
so basicly evolution is based on your possibilities and chances. The fittest may survive because "mama has a gun"
the humans that used their brains instead of their strenght survived and where able to pass their genes. so more brainiacs where born while the schwarzeneggers either died out or became governours.
amongst those humans who had brain and used it the ones who found families (=backup, cover, learning aso) lived on and passed their knowledge onto a broad ground. The other ones who didnt also did not befenfit from all the horde advantages and either had to learn everything from start or died by breaking on leg and not being able to hunt anymore.
those brainicas who survived either split into a social system that grants more efficienty by deligating different jobs to different units so they could survive hunger and illness or all of them where running arround doing the same and where killed by one incident they did not expect.
thats all about there is. being as we are granted us one big advantage over all the other humans that where: we are alive.
and being alive is a big plus if you want to spread genes
-->..."Where does the spirit of sacrifice come from"
first of all it is not a spirit but an instinct. And as said above, those goups who didnt have this instinct or surpressed it lowerd their chances in different circumstances and died out.
If you are weak and have a lousy phsical set up like humans have you need to find alternative back ups that will make a survival possible.
a social system as we have it now is also based on spread knowledge. if you cut out one single animal or human from a horde and place him on an island he wont be able to grow social attributes and will have a very hard time to addapt to our living system.
our rights or wrongs or does and donts are what we agreed on and not a universal sheme. writing helps to spread ideas, talking helps to interact and so on.
and ad a matter of fact languages and talk have to be learned by everyone of us after we are born and dont just pop out.
they are based on our social surrounding. Thats why there are different languages and writings.
if there would be an universal and god sheme there wont be so much difference.
god said "there shall be light" but can anyone tell me did he say that in english or does he able espaniol.
if we are a refelction of what god is then he is not capable of speaking and writing
Maybe then this thread will someday be called an "intelligent conversaton".
