The Ant Odometer – Data Analysis
Have you ever thought about how ants navigate the world? Some ants use pheromones or other chemicals to follow trails. Other ants have a novel way of finding their way home; they count steps!How do these little biological Fitbits do this? How did scientists confirm that the ants counted steps? In this research study, scientists…
