Honey bees can count up to four, Australian researchers have found, but no higher. In a University of Queensland study, bees repeatedly flew to the same marked spot in a tunnel, even when it did not hold food, Reuters reports. "We find that if you train them to the third stripe, they will look subsequently in the third stripe," one researcher said.
"The more we look at these creatures that have a brain the size of a sesame seed, the more astonished we are," the researcher said. "They really have a lot of the capacities that we so-called higher human beings possess."
