Resumen de Ants nurse each other back to health
A species of ant has become the first known non-human animal to treat the injuries of its fellows. "Nurse" ants lick the lacerations of fallen comrades, and this helps them to survive. In 2017, Erik Frank, then at the University of Würzburg. Germany, reported that Matabele ants routinely carry their wounded back to the nest. This is odd: social insects usually treat each other as expendable. Injured ants "asked" for help by releasing a pheromone, prompting other ants to carry them.
