There are over 6,900 大发language currently spoken in the world, yet all of these are similar in at least one respect: duality of patterning。 Study any spoken language and you’;ll find it is based on a specific core value: complex linguistic units that have meaning (words) are broken down into constituting  fundamental linguistic units that have no meaning (sounds)。 So, instead of having to remember and distinctly utter a sound for every word in the lexicon, humans have learned to combine a much smaller number of sounds to form words。 Though still debatable, most linguistics agree that this optimal route of patterning sounds to form language is actually rooted in our biology。 This is how all languages work, so it must be in our genes which have adapted to evolutionary pressure to lend us words when beating stones and screaming didn’;t cut it anymore。 A growing new language, however, may dismiss this theory altogether。

A concrete sign language

The consensus is that language was spurred by evolution and as such there must be a gene that encodes it。 The fact that all languages employ the same duality of pattering has so far supported this idea。 But what about  Al-Sayyid Bedouin Sign Language (ABSL)? This peculiar form of sign language recently emerged in a small community with high rates of inherited deafness in Israel’s Negev Desert (inbreeding seems to be the cause) and seems to work, on a structural level, in contradiction with anything we’;ve been used to。 Instead of using vowels or syllables, ABSL defines words by holistic gestures, so every word has its own distinct combination of gestures。 The word “;lemon”; for instance is conveyed by gesturing a lemon squeezed in the hand。 In contrast, other sign languages like American Sign Language (ASL) create words by re-combining a small collection of gestural elements such as hand shapes, movements, and hand positions –; just like any other spoken language for that matter。
