A rattle will only make noise if you shake it. Children learn this principle of cause and effect early on in their lives. However, animals like the wolf also understand such connections and are better at this than their domesticated descendants. Researchers at the Wolf Science Center of the Vetmeduni Vienna say that wolves have a better causal understanding than dogs and that they follow human-given communicative cues equally well. The study in Scientific Reports provides the insight that the process of domestication can also affect an animal’s causal understanding.
