Farming: The Three Sisters and the First Farmers

History Class · Level band: Grades 4–6

DRAFT — CULTURAL REVIEW PENDING. These history classes are a publisher’s draft blend of the Collection’s Indigenous history research, standing on its own website. Indigenous cultural review precedes any public release of this strand. Readings carry the research labels unchanged: Documented Fact · Tradition — the people’s own account · Debated / Claim. This page carries no advertising.

English edition — the language editions of the history classes are outstanding and will follow the site’s translation pattern; none is fabricated here.

For the teacher — teacher-facing guidance for this class stands in this box only; the reading below is the student reading. Selection note: this reading is a selection from the full research entry, made for this band. The full entry stands in the senior classes. For the teacher: the reading carries the research labels unchanged — Documented Fact, Tradition (the people’s own account), and Debated / Claim. Keep the three apart in discussion, exactly as the entry itself does.

Farming: The Domestication Centres and the Great Systems

Status: Researched draft — cultural review pending

How to read this entry: Documented fact = published archaeology, archaeobotany, genetics, or ethnohistory cited in Sources. Tradition — the people's own account = Indigenous oral history or a people's own published teaching, labelled as such. Debated / Claim = a point where published scholars disagree, or a figure given only as a sourced range. Scope note: a history of farming in the Americas, system by system, each named for its own people and place.

Flagged claims and weakest-sourced points: (1) Maize chronology — genetic (~9,000 BP), Xihuatoxtla (~8,700 cal BP, indirect) and cobs (~6,250 cal BP) measure different things. (2) Hohokam totals (200–250 to ~500 miles; 25,000–70,000 acres) vary by scope counted. (3) Chinampa area and yields are model outputs, Armillas's figures argued downward. (4) Maya wetland-field regional scale — Pulltrouser secure, wider claims not ground-truthed. (5) Suka kollus extent and tonnages vary by report. (6) Chuño antiquity beyond c. 600–1000 CE evidence, and precise potato variety counts. (7) EAC synthesis dates still revised by AMS work.
