"We [humans] (distinctively human) didn't suddenly come into being, consciousness didn't suddenly come into being, and nor either does an idea in our head suddenly come into being." (source 
section 11) "The argument that there is some mystical (mysteriousness) non-natural aspect to languages is rapidly being proven false in the domain of natural language processing today." (source section 22) But the appearance of human competencies, language and ideas seems sudden and mystical. Like an "'evolutionary saltation between pre-linguistic and linguistic abilities'" (source section 21, quoting Hart), like "evolutionary short cuts such as an innate capacity for language (language 2)" (source section 21), like a "'gap' in evolutionary history" (source section 11), like "'a discontinuity'" "'between mere accidental associations and intentional signs'" (source section 24, quoting Hart).
