Prime Directive and General Order 1 are the same thing.
The figures seen in the Kaminar population history do not make much sense to me.
So, over 2,200 years ago, there 23059 Ba'ul, 26534 unevolved Kelpien, and 29169 evolved Kelpien. According to what we see, the evolved Kelpien did not grow larger in numbers, staying slighly north of 29,000 but south of 29,500. Instead, the unevolved Kelpien were wiped out and the Ba'ul were reduced to 250 or so individuals. Then, suddenly, the Ba'ul jump to 810 individuals and the evolved Kelpien were wiped. out About this time, there were 30 or so unevolved Kelpiens. So, if the evolved Kelpiens are wiped out, then where did the unevolved Kelpiens come from? There were no unevolved Kelpiens, which would seem to be a requirement for them to exist, available for a new breed of their species. They were dead when the Ba'ul were on the ascendancy. And, if the Ba'ul did succeed in wiping out their enemy, then why woud they resurrect a dead species?
