Considering that charaters like Artica and Rahi seem to have origins outside of AlphaCorp, and family far older than Tavi, I'd say that the station may have been run by humans, but experimented on anthros.

well that's assuming that Tavi escaped recently, that could have been 20 years ago, also the station could have been operating long before Tavi was created, they could have been soliders that escaped or got stranded which is how we got anthros from outside AlphaCorp. However I'll admit I only just gotten to learning Tavi's origin and is just guessing at the lore
