Neurobiologists have discovered cells in the crow brain that respond to a specific number of items. The study provides valuable insights into the biological roots of counting capabilities. What makes this finding even more interesting is that a long evolutionary history separates us from birds; as a consequence, the brains of crows and humans are designed very differently.
