You should bring up that deurtue dude in the Philippines . <| sep |> I think there is something to this line of thought <| sep |> Yeah , but they don ' t broadly generalize that the entire white population is a bunch of thugs abusing welfare . <| sep |> It ' s important to realize that there ' s not just one type of ant . There ' s over 20 , 000 species of ant and they show a lot of behavioral differences . There ' s three major methods of navigation that have been described in different ant groups , though each has numerous variations . There ' s path integration dead reckoning systems , visual mapping systems , and social scentbased systems . Probably most types of ants rely on several methods rather than just one . Most ants that have been studied switch to a fourth type of navigation when they are lost or displaced and they also use essentially the same system when foraging . This is called search loop behavior and was described in this paper on Cataglyphis . It ' s since been shown in other types of ants with different primary navigation mechanisms . In fact , it ' s also been shown in many other organisms including humans . It ' s considered an optimal search mechanism and is commonly used in robotics and computer programming .
