=Of course= there is individual-to-individual biological variance,
right down to the DNA, but, within the 'normal' range of Human
interactive dynamics, such biological variation is 'moot' because, if
a biological variation results in reduced adaptability, that version
of the biology is at a deficit when environmental conditions become
modified beyond the range of its adaptability.
With respect to such, the contemporaneous existence of
widely-dispersed populations demonstrates that adaptive-survival
capacities are quite uniform across populations [I'm reminded of a TV
News show that dealt with Young Immigrants to Minnesota(?) from
Uganda(?) - the main 'difficulties' were cultrual, not with respect
to the pre- and post-Immigration climate differential].
So, this view holds that, while there's individual-to-individual
biological variation, the important stuff is
adaptability-to-environment - which is, once again, 'just' the one
overall energy-flow actualized within various environments - and what
the individual-to-individual biological variation constitutes is
'just' more 'climbing'-up the downhill energy gradient inherent in
the overall energy-flow - "going up the down staircase", the single
goal being always enhanced adaptability - enhanced survival.
My earlier discussions that take this stuff down to the molecular
'level', demonstrating that it is the one overall energy-flow that
directs evolutionary progress applies here.
And, no, I do not miss the 'irony' of the fact that, in the midst of
a discussion of 'adaptability', I'm coming close to my own failure to
NDT is all about acting consciously to enhance adaptability.
I could've taken the understanding and 'used' it on my own behalf,
but I saw that the thing to do with it was to give it to the
Children - in the service of all.
I understand the consequences of my Choice - it's stuff augments TD
E/I within others' nervous systems - given that augmented TD E/I,
folks'll 'move away from' me.
It was just clear to me that the thing to do was 'stand-in-the-face'
of such - to lift folks up out of the 'blindly'-automated 'tyranny'
It's been 'Hard', but I've no 'regrets' - the Children are worth it -
so is the future of Humanity that flows out of NDT's understanding.
