I just don't see any of the characters in that show evolving into the characters in TOS. I see them becoming totally different characters, which would mean TOS could be totally overwritten. Nimoy's Spock would be overwritten by a more emotional Spock. The relationship between Spock and McCoy would be different. Chapel would be totally different as she is quite different from Barrett's Chapel (not a bad thing in my book if her unrequited love for Spock ends and more possibilities for her character open up). Year 1 would be an entirely different crew in many ways. They would not be the TOS crew.
As far as Spock mind melding, I would imagine he learned it from a teacher. The question would be why it was taught if it was some kind of formal lesson. If not, he must have been taught it surreptitiously, or perhaps it's taught in his clan, if they are all "melders." (There were likely to be warnings about letting others know he or the members of his clan could do it or at least acknowledging that they could do it.)
