1. Story
2. The family spanning North Africa, the Horn of Africa and Southwest Asia, whose branches are conventionally given as Semitic, Egyptian, Berber, Chadic, Cushitic and — disputed — Omotic. It has the deepest continuous written record of any family on Earth: Egyptian is attested from around the beginning of the third millennium BCE and Akkadian not long after, so two branches are documented for roughly five thousand years. The family is bound together by grammatical evidence of the kind hardest to borrow, above all a shared system of prefixed and suffixed verb conjugation and a two-gender pattern in which the feminine is marked by a t element. Its homeland is genuinely open: the greatest branch diversity lies in Africa, which by the standard diversity argument favours an African origin, most often placed in the Horn or the eastern Sahara, while the Semitic branch's Asian distribution and the agricultural associations of some reconstructions have supported a Levantine case. Omotic's membership has been questioned repeatedly, and the family's time depth — plausibly beyond eight thousand years — sits at or past the limit where the comparative method retains resolution.

21. Evidence
22. Supports the four-family classification of African languages, including the establishment of Niger-Congo and Afroasiatic as currently understood, by multilateral comparison. V55 verification basis: this session had no access to any source — WebFetch was egress-blocked for every host attempted and the WebSearch budget was exhausted before authoring — so the cited work was not retrieved, and no page, volume or figure quoted from it was re-checked. The present standing of each of the four groupings is characterised from working knowledge of the subsequent literature, not from any survey retrieved in this session.
23. Supports the general account in this pack of the comparative method, the regularity principle, contact and borrowing, glottochronology and its critics, and the definition of a language isolate. V55 verification basis: this session had no access to any source — WebFetch was egress-blocked for every host attempted and the WebSearch budget was exhausted before authoring — so the cited work was not retrieved, and no page, volume or figure quoted from it was re-checked. No chapter or page is cited, because the book was not opened in this session; the citation identifies the work a curator should check the general account against. This is the source named in the Journey declaration.
