I must say firstly that I am a trifle embarassed by the regurgitation of this throw-away midnight ramble Alex...., but the content is still I feel worthy of further exploration.
I am indeed gratified to see the possible descendents of an African Eve so deliniated- and endowed with such a colourful nomenclature, but I still have two basic problems with the concept.
As I have already stated- the difficulties facing the near uniform distribution
of homo-sapiens over the entire landmass in what is to my mind still a fairly short time span; and the 'nature of mutation' which was so precise as to establish changes in our own and other species at a single point in time and location.
I have suggested the migrationary difficulties- in the above and other posts- facing a uniform human migration, so I will move on to the 'nature of mutation'.
There are only a few possible candidates for the 'impulse' that might change or introduce a species- an event that has not happened in recorded history; I suggset a few:
Solar storms on a scale larger than we have as yet recorded may have the potential to cause genetic mutation- but if so it is unlikely that the effect would be limited to a single embryo or species.
But the fact of 'solar flares' itself suggests that there may well be greater stellar storms coming from elsewhere in the galaxy- massive cosmic surges erupting from multi-star systems or supernova that shake up the mitochondricals of all embryonic tissue everywhere in their wake- hardly a precise evolutionary or selective process though?
And then of course....., there is the possibility of 'intentional design'; that there was, how shall we say,..., a guiding intelligence behind the miraculous perfection of the creation that is all around us.
And I am obliged to note- as I look out my window on this pristine autumnal morning- just how well everything seems to fit so seamlessly together: the butterfly feeding off the hibiscus flower- its immediate evolutionary predecessor; the sprightly willy-wagtail dining on that same butterfly- its immediate evolutionary predecessor; the patient abyssinian feline that will shortly dine on the now not quite so spightly willy- a most timely evolutionary predecessor....., and so it goes. Just how is it that EVERYTHING seems to evolve as it is needed to give sustenance to the forthcoming life-forms-..., kind of mind-boggling I calls it.
So...., so what I would suggest overall is:
1: That the 'forms' of life, are an evolutionary process;
2: That this evolutionary process is supervised by 'MIND'[ we are not talking Goddy or Santa Claus here ];
3: That the mechanisms used to modify or mutate DNA material are stellar activities- the movement of constellations over certain portions of the earth for minor changes; the holocausts of solar and galactic storms for major elective surgery;
4: That when a mutation takes place within a species..., it is not confined to a single location- it will occur wherever there are receptive preliminary life-forms available for further refinement; in the case of homo-sapiens, wherever there were primates advanced enough to recieve the new technology- no doubt Africa, but probably also Asia, and Sth America.
