Emergence of living language: ontogeny–phylogeny framework and other parallels of linguistics and biology

Although language is something deeply embedded in our nature, the question of its origin is of the same order as the misty question of the origin of life. I point out that the core of the problem can be rooted in the dichotomy between language and speech, similar to the dichotomy of genotype and phenotype in biology. Following the ontogeny–phylogeny framework, I propose that studies of language ontogeny, especially its early stages, can bring a new understanding to language, same as the study of communication in non-human primates.
