Honingbijen kunnen tot vier tellen en herkennen nul, blijkt uit onderzoek

Honeybees can count up to four and recognize zero as a quantity, according to research from RMIT University. Scientists trained bees to associate visual stimuli with different numbers of elements, finding that bees consistently chose images with fewer elements and applied this behavior to new images, indicating genuine numerical understanding rather than memorization. This ability mirrors responses in primates and young children, and is particularly significant because honeybee brains contain only one million neurons compared to 86 billion in human brains, suggesting numerical cognition does
