The development of language is, of course, of great historical interest.
The flourishing of what we call “civilization” clearly parallels the development of writing. In the genetic record, we find that gene sites for speech and the later-evolved conceptual abilities that cluster around the genetic band zones for LANG72 (as well as for the bands LANGs 1 thru 64) make their appearance universally in the genome only around 15,000 B.C.E. Additionally, the five gene clusters for art/abstraction (ABSTs 144 thru 149 also seem to appear in the 15th millennium B.C.E.)
However, it is only much more recently – less than one hundred years ago – in the middle of the 21st century – that the PROJ cluster suddenly makes its appearance in the human genome. And this is due to the fact that the PROJ cluster was in actuality introduced or inserted via direct Grid wire-downloads (or GWD’s) in the late 2040’s and early 2050’s). The PROJ cluster gained rapid ascendancy in the population – with three locations on the band axis, notably on the R band and Z band zones.
Of course these were the famous (or infamous) Grid PPP downloads, as per the Unanimity Arrangement. We know, of course, that it was in fact, these “necessary, advantageous, and quite legal” invasions by the Grid (according to Wikipedia 2045) into the human genome which led to the Grid’s dissolution.
………We see that by the middle of the 21st century vocalized speech had greatly decreased in frequency as well as in overall quantity – an 80% decrease in actual volume of verbalized statements according to our most recent estimates (Clarkson, Clarkson, and Markowitz, also Sura and Mbote, 2128). And the decrease in quantity was accompanied by a discernible decrease in what must only be called quality as well, as many of our art historians like to remind us – and rightly so I may say in this case.
Vocalized speech and face-to-face interactions had certainly been very greatly reduced, indeed practically replaced in the beginning of the 21st century by texting, phoning, and later by old-fashioned linking and the “underground” linxing or “X-rated” networks. Additionally, around 2020 the standard up/down channels were texted or “zapped” directly onto the Grid. As a result of these changes, less complexity was demanded of language. Of course, much less complexity of thought (measured by the standard B scales and loop analyses) was required once communication had became digital in the early 21st century. There was, additionally, less need for mental arithmetic, or other reckonings,as well as less need for and memory. Naturally, these cultural changes required no genetic alterations, although genome records indicate that some movement (perhaps 8 to 10%) occurred at this time in the LANG72 cluster on chrome 16.
Additionally, the new “exterior” (the non-spoken) language vehicles reduced the need for many of the old non-verbal and auditory nuances that had accompanied traditional vocalized speech. Speech behavior and – at the same time in history – many of the old patterns of sexual and social behavior – had simply been altered. As mentioned, genetic changes in the LANG72 cluster were also apparently beginning to occur (according to Jones, Jones, and Markowitz, 2218) during the middle of the 21st century – only seventy or eighty years ago.
To summarize: Because less nuance and less cognitive complexity were required of language in the 21st century, traditional face-to-face spoken language, and (even more importantly) the cognitive skills associated with spoken language, began to atrophy throughout the population world-wide.
