[Star Trek] Possible plot hole from the TNG episode "Ensign Ro"
In this episode, Picard states the following:
>Captain's log, supplemental. I read about the achievements of the ancient Bajoran civilization in my fifth grade reader. They were architects and artists, builders and philosophers when humans were not yet standing erect. Now I see how history has rewarded them.
Problem is, Homo sapiens was already "standing erect" as a species when its anatomically modern form evolved about 100K years ago. One might argue that Picard was using "human" as an umbrella term for any species from Australopithecus onwards, but if that's the case, then the Bajorans would be something like four million years old as a civilization. Per Star Trek rules, shouldn't they be energy beings by now?
