Scientists have discovered episodic memory in dolphins

They conducted an experiment and offered eight dolphins a game - people stood along the edges of the round pool, but only one of them had the ball in their hands. The animals had to swim up to the right person on the first attempt and ask him for a toy. The experiment was carried out for two days. All eight dolphins successfully answered the question "where?", and only one of them did not cope with the question "who?". So the animals demonstrated that they not only remember the event, but also the context accompanying it.
