The view of language as an adaptive system treats a language as an organism subject to evolutionary principles. Languages have been naturally designed, after generations of child acquisition, to be easily learned by children in their earliest years. Nicaraguan Sign Language (NSL) serves as the primary daily language of approximately 1,500 deaf people, ranging from 4 years of age to the mid-50s. One line of evidence has focused on changes in expressions of motion events, from holistic to segmented signing. The changes in NSL resemble certain changes documented in the grammaticalization of spoken languages. Evidence from children learning mature sign languages suggests similar processes during typical acquisition. Children use grouping, analyzing, and aligning strategies for many kinds of learning. Mature natural human languages have been subject to learning so many times that we cannot perceive the effect of another pass.

Newborns show remarkable speech perception abilities despite their immature auditory systems. Newborns and very young infants exhibit an extensive repertoire of basic auditory, speech perception, and learning skills that allow them to crack the linguistic code in any language they encounter in their environment. Newborns show abilities that are already shaped by learning -from speech heard in the womb. Prosody serves as a bootstrapping cue from very early on in language development, allowing infants to learn about one of the most fundamental properties of their mother tongue, its word order. Infants can rely on prosodic boundaries to access syntactically relevant units. Minnesota Symposia on Child Psychology: Human Communication: Origins, Mechanisms, and Functions RelatedInformation

Infants may show these increased responses in their brain responses, their physiological reactions, and how they control their own behavior to elicit the presentation of different sounds. Some newborn listening preferences are clearly rooted in prenatal experience. Having a bias for listening to speech or looking at signed language can help infants put together elements of their communication system. Newborns may listen to speech and rhesus calls equally because of the acoustic properties they share from being biological or primate-produced vocalizations. The ability to orient to the relevant social beings in their environment might contribute not only to infants' language development but also to social development. Communicative gestures are essential forms of non-verbal referential communication for adults, allowing us to relay information and share interest with others.
