This is a dig at a rather disappointing episode from the early Nineties Next Generation period called “The Chase.” If it were done today via the Paramount+ regime, the execution would more likely be a more satisfying mini-arc within Strange New Worlds or a joke in Lower Decks…yeah, Picard and Discovery would continue to make this suck.
The point is, back when ST:NG was a syndication-only show, the writers were from the two main genres Hollywood specialized in for TV: SitComs and Procedurals. Guess what kind of crap Star Trek got? So this galaxy-shattering idea stating why all the dominant star-faring races are humanoid, yet Terrans received no special foreheads (Klingons, Cardassians), nose ridges (Bajorans) or pointy ears with a love of Pete Rose’s haircut (Vulcans)?
The additional joke is the awesome actor Jeffrey Combs has been in at least three of the shows (DS9, Enterprise and Lower Decks) as the Andorian Shran, two Ferengi, an evil AI and the cloned Vorta Weyoun. He’s just a great actor and he’s probably patient with sitting in a makeup chair.
