Yes, that's a good point. Not evolution. But, the impact remains the same.Can we not use forced evolution. Bad enough Star Trek writers don't understand evolution but this is the natural Kelpian life cycle. The Ba'ul were culling them at puberty, essentially. Sure, I expect there will be lots of bad consequences from this but there was no forced evolution. There was no change of the species they just didn't get Logan's Run-ed.
