Question

If FLN is uniquely human, what did this evolve from? What would be a "broader version" of FLN that our neighbors in evolutionary history may have had? Would it simply be FLN but without the capacity for discrete infinity?

Answer 1

it evolved for functions other than language, and that this nullifies ‘the argument from design’ that sees language as an adaptation”.

broader version is comparative approach to understanding the many shared cognitive mechanisms that are part of the human language faculty.

We offered discrete infinity as a starting point for discussion and research, “restricting attention to FLN as just defined but leaving the possibility of a more inclusive definition open to further empirical research”
