Rats

Rats can use the rhythm of human language to tell the difference between Dutch and Japanese, researchers in Spain reported Sunday.
Their study suggests that animals, especially mammals, evolved some of the skills underlying the use and development of language long before language itself ever evolved, the researchers said.
It is the first time an animal other than a human or monkey has been shown to have this skill.
