A recent study looking at how colonies of ants regulate their foraging behaviour has caused a bit of a buzz online. A lot of the coverage has focused on a similarity highlighted in the press release, which says that the ants “determine how many foragers to send out of the nest in much the same way that Internet protocols discover how much bandwidth is available for the transfer of data”. While it’s wonderful that the study has received so much attention, I can’t help but feel that the really interesting aspect of this study has been overlooked in the excitement about the “anternet”. While the similarity between the two systems is striking, I’m more fascinated by a basic difference: unlike our computer networks, the regulation system in ants isn’t purposefully designed but emerges from uncoordinated decisions made by individuals.
