1. genes don't *want* anything...they only carry blueprint information
2. organs, subsystems, and parts of the body don't *serve* genes. they exist
as they are because their attributes make the organism most likely to
survive to pass on the blueprint in its progeny.
4. 1 and 2 above show the premise of 4 to be a bad conclusion.
6. the premise of 4 brings you to premise 6...which is again incorrect
because of 1 and 2 (and now 4) above. genes *know* nothing. they are only
*successful* if they are passed on in greater frequencies in a
7. see 4 and 6 above, as each premise since 4 has been wrong...inclusive of
7...all for the same reasons. the only environmental *information* a gene
responds to is life and death. genes are certainly able to mutate due to
environmental factors, but be assured they certainly aren't *aware* of these
changes. they simply have a new blueprint from which things will either be
successfully or fatally created.
as for your examples, *any* possible configuration (including social
behaviors of insects in constructing hives, pacifism, barbarianism, etc.)
can be had in evolution. the expression of genetics is based on
survivability. should a peaceful species propagate more successfully than a
war-like one, we'd see more peaceful kinds of that species...however, don't
be fooled into thinking genes themselves *want* peace. under different
factors, the pendulum could swing in favor of the latter.
btw, the only thing in evolution that can occur spontaneously is
mutation...and it would be an astronomical leap in probability statistics
for such a system to arrive in an organized fashion as to yield even a
single child the ability to speak or handle mathematical operations in any
exceptional fashion beyond its inherited capacities...even latent
combinations. such a notion is akin to thinking all things arose as they are
due to some divine providence.

| Hi , I'd like to contribute the following consideration :
| 1º Genes want to adapt to new environments ( evolution ) .
| 2º Organs , subsystems and parts of the body are instruments that
| serve the genes which developed them ; ( genes want the organs ,
| subsystems and parts of the body for adapting to new environments or
| environmental circumstances ) .
| 3º Sensory nervous system is a part or subsystem of the body ( in
| animal kingdom ) .
| 4º So , sensory nervous system is an instrument that serve the genes ,
| for evolving and adapting to new environments ; ( genes want - also -
| sensory nerves for adapting to new environments ) .
| 5º The function of sensory nervous system is to provide the ability to
| refer proper motive actions to external objects or information ; the
| function of sensory nervous system is to detect external information .
| 6º So , it seems that , in some way , genes should use the sensory
| nervous system to " get information " , or to " watch " or to " know "
| the environment , and , this way , to evolve ( mutate ) in an adaptive
| manner . Or it seems that this idea has a certain scientific
| characteristic .
| 7º So , nervous system should be able to influence in some manner in
| some of the mutations of genes , according to environmental
| information .
| If it happens , it probably occurs as any chemical conditioning in the
| formation of reproductive cells , where nervous system can take part .
| Maybe some specialized neurons can control the release of certain
| chemical substances . But a neuro-chemical mechanism of this nature
| has not been described yet , and I think it should be an amazing
| discovery .
| Examples :
| > External temperature determines the sex of eggs of crocodile .
| > Recently Courtney Miller and David Sweatt have proved the
| importance of methylation of DNA for cerebral retention of memories .
| > An important example : the genetic internalization ( genetic
| encoding ) of learning . It is specially visible in primitive animals
| ( conduct of bees for building the honeycomb ; conduct of many insects
| for building their lairs ; conduct of certain birds or fishes in their
| migrations ) . Could future human babies spontaneously develope innate
| aptitudes or abilities for speaking or handling mathematical
| operations ?
