>>11967851After watching the arc with my ex and finishing a degree in an evolutionary science I'd say viruses and bacteria are the closest thing to the ants in terms of the specific mechanism you're talking about where they eat other things and develop traits. viruses moreso because replication is basically their entire point.
In terms of literally everything else about the ants besides this replication mechanism, humans are closest to them. War crimes, massive animal slaughter houses, disregard for other forms of life.
