Deaf Children invent new language

Reuters:

Deaf children thrown together in a school in Nicaragua without any type of formal instruction invented their own sign language -- a sophisticated system that has evolved and grown, researchers reported on Friday. Their observations show that children, not adults, are key to the evolution and development of language, the researchers report in Friday's issue of the journal Science.

This is facinating as it shows how ingrained language is into the very structure of humanity. We are wired at birth for language, the structure and particulars are determined by culture, but the building block are already a part of us.
