Evidence from studies on homesign systems demonstrates that isolated deaf individuals naturally innovate and develop their own structured communicative and linguistic systems.

The analysis

The claim asserts that isolated infants naturally develop spontaneous language systems. Both retrieved papers document homesign systems innovated by individuals lacking access to standard spoken or signed languages, showing that such individuals develop structured linguistic properties without traditional cultural transmission or multiple generations of users. Thus, the evidence strongly supports the claim.
