    From an article I found online:

    A team led by Matthias Wittlinger, a biologist at the University of Ulm, Germany, made modifications to desert ants […]. After setting up an ant home outside the lab, the researchers let 25 ants take a 10-meter trip from their nest, then collected them. For one group, the team glued tiny stilts to the insects’ legs. For another, they clipped the legs down to stumps. And for a control group they left the legs alone. Then the researchers gave each ant a piece of food and set it free. With morsels of food in their jaws, the ants immediately headed home. If desert ants do indeed use an internal pedometer, then the modifications should mess up their calculations.

    Not only did the stilted and stumpy ants not make it home, but they also misjudged their distances exactly as the researchers predicted. The ants on stilts went about 5 meters too far before stopping to search for the nest, whereas the stumpy ants stopped about 5 meters too short […] (Control ants got back home just fine.) After the modified ants were returned to the nest, they were able to go out and get back home just as accurately as normal ants, which should be the case if they’re keeping track of the number of steps.

      Quorum sensing does not require a conceptual framework of numbers. The conceptual framework is the harder part, your brain and many cells perform quorumsensing and computations all the time that you would find difficult to do by hand, or to do symbolically.

    The second half of this experiment is far less wholesome:

    To verify their findings, these scientists reran the experiment by cutting off ants’ legs at the knees. Those ants consistently undershot their targets, showing definitively that ants do actually count their steps.

    So yay, verified results via torture!

    • I immediately know why and its not about steps its about communication. How do the ants know how many steps to the food? its because other ants communicated it. Im 99% sure that is what the study was about. So there is a lot they are verifying. communication. mathematical concepts, how they parse distance. remember the foot is called that because it was sorta an average size of a foot. yard is basically a stride.
