Machine learning reveals how often fish schooling evolved—and repeatedly disappeared

Researchers used machine learning to map schooling behavior across nearly three thousand fish species over 350 million years. They discovered that collective swimming evolved about 60 times and disappeared roughly 320 times. The findings show that flexible animal behaviors can be quantified and tracked across large evolutionary trees.
