One of the main intellect that they can do this is the leaning of their colonies to distribute by “ budding . ” What this means is that group in one colony can just split off and start up a whole fresh settlement without feature to horde and start over .
They do n’t even need a fag to start with . proletarian can develop one , and this makes it even easier for groups to separate and bulge young colonies .
