The First Speaking Humans Sounded Like Yoda

Linguists have long labored to construct a hypothesis about an original, or mother "proto-language" that humans used in East Africa some 50,000 years ago. For quite some time these linguists have believed that this proto-tongue was the original language spoken by humans, and that all language can inevitably be traced back to this place and time. Now two specialists in the evolution of human language argue in a new paper written for the Proceedings of the National Academy of Sciences that this original language sound like Yoda. That is to say that the arrangement of the words "I like you" that we are familiar with would have been uttered as "I you like". And while this makes for an imperfect analogy - given the subject and object agreements, for intent I think Yoda would have said "You I like", it is a useful illustration of how we began to speak to each other
