Insects exhibit remarkable cognitive skills in the field and severalcognitive abilities have been demonstrated in Drosophila in the laboratory. Bydevising an ethologically relevant experimental setup that also allowscomparison of behavior across remote taxonomic groups we sought to reduce thegap between the field and the laboratory, and reveal as yet undiscoveredethological phenomena within a wider phylogenetic perspective. We trackedindividual flies that eclosed in a small (45mm) arena containing a piece offruit, connected to a larger (130mm) arena by a wide (5mm) doorway. Using thissetup we show that the widely open doorway initially functions as a barrier:the likelihood of entering the large arena increases gradually, requiringrepeated approaches to the doorway, and even after entering the fliesimmediately return. Gradually the flies acquire the option to avoid returning,spending more relative time and performing relatively longer excursions in thelarge arena. The entire process may take up three successive days. Thisbehavior constitutes coping with space neophobia, the avoidance of untroddenspace. It appears to be the same as the neophobic doorway-crossing reported inmouse models of anxiety. In both mice and flies the moment-to-momentdevelopmental dynamics of transition between trodden and untrodden terrainappear to be the same, and in mice it is taken to imply memory and, therefore,cognition. Recent claims have been made for a deep homology between thearthropod central complex and the vertebrate basal ganglia, two structuresinvolved in navigation. The shared dynamics of space occupancy in flies andmice might indicate the existence of cognitive exploration also in the flies orelse a convergent structure exhibiting the same developmental dynamics.
