Bewilderingly, Hydra seemed to follow the same set of behaviours under the full range of stimuli used by the researchers. A machine - learning algorithm developed by scientists at Columbia University can approximate the behaviour of simple animal models . The researchers used extensive video footage of hydra , freshwater - dwelling organisms with tubular bodies that lack brain or muscles , to teach the algorithm the entirety of the animal ’s behaviour . The algorithm was able to understand and replicate the animal ’ behaviour , including their responses to stimuli and environments .
