ASSUMPTION. Two isolated groups of a sophont people may diverge up to one characteristic and one dice roll per 100,000 years. Both changes are independent of one another.
EXAMPLE. Two Human colonies are founded, and their Human empire evaporates, leaving them isolated forever.
Humans are SDEIES-222222. That's 2D each for Str, Dex, End, etc.
Both diverge in (a) a random characteristic and (b) a dice roll value, every 100,000 years.
+0:
colony A: SDEIES-222222
colony B: SDEIES-222222
+100,000:
colony A: END changes to VIG. No dice numbers change.
colony B: DEX changes to AGI. No dice numbers change.
colony A: SDVIES-222222
colony B: SAEIES-222222
+200,000:
colony A: SOC changes to CHA. No dice numbers change. We denote that CHA is non-genetic with an asterisk.
colony B: No changes.
colony A: SDVIEC*-222222
colony B: SAEIES-222222
DIVERGENCE OF SOPHONTS
You can use this to guesstimate how "far apart" two related sophont groups are. Of course, you first have to decide that the two groups are related!
DIFFERENT RATES
The rate of change will be different based on the environment, the primary star's energy level, and so on. Go nuts.
HIGHER RESOLUTION
You can use the process on a shorter time scale (centuries or millennia perhaps) for non-genetic characteristics; for example, EDU and TRA will flip-flop many times. Similarly, SOC will interchange with non-genetic CHA and KAS.
When moving to non-genetic CHA and KAS, mark the end of the UPP with an asterisk (*). This lets the reader know that the final characteristic is non-genetic and therefore not a species differentiator.
