Collective behavior emerges from genetically controlled simple behavioral motifs in zebrafish
Since Darwin, coordinated movement of animal groups has been believed to be essential to species survival, but it is not understood how changes in the genetic makeup of individuals might alter behavior of the collective. Here we find that even at the early larval stage, zebrafish regulate their proximity and alignment with each other. Two simple visual responses, one that measures relative visual field occupancy and the other global visual motion, suffice to account for the group behavior thatdoi:10.1101/2021.03.03.433803 fatcat:i6sisqr2rzajvc2vzlejoyntpm
