Немецкие исследователи научили рыб-зебр и скатов складывать и вычитать числа

German researchers have made a groundbreaking discovery in the field of animal cognition, demonstrating that zebra fish and stingrays possess the ability to perform basic arithmetic. In controlled laboratory experiments, these aquatic animals were taught to add and subtract small numbers by recognizing color-coded symbols. This research challenges previous assumptions about the intelligence of fish and suggests that the neural pathways required for mathematical reasoning are much older and more widespread in the animal kingdom than once thought. The findings open new avenues for studying the evolution of numerical skills across diverse species.
