All around the world children play hide and seek. But do animals do so too? In a recent study, scientists from the Einstein Center for Neurosciences Berlin and the Humboldt University Berlin show that rats can quickly learn a rat-human version of the game and can easily switch between different roles – hiding and searching. The scientists suspect that hide and seek has its origins much earlier in evolution than previously thought. The study has been published on September 13, 2019 in the journal Science.
