OVERVIEW

This subfolder contains 16 documents covering Population Regional Genetics within the Genetics & Human Origins section. Topics include Domestication Genetics — How Humans Reshaped Life, Population Genetics and Hardy-Weinberg Equilibrium, Ancient African Genetics, Oceanian Genetics and Pacific Migration, Americas Peopling Genetics and 11 more topics. Key themes span ancient dna, admixture, y chromosome, migration, yamnaya, corded ware.

KEY POINTS

• L_2_01 — Domestication — the genetic transformation of wild species into human-dependent organisms — ranks among the most consequential biological processes in Earth's history.
• L_2_02 — Population genetics — the mathematical study of allele frequency change in populations — provides the quantitative framework underlying evolutionary biology.
• L_2_03 — Africa harbors the greatest human genetic diversity on Earth — a direct consequence of being the continent of human origin, where populations have accumulated genetic variation for ~300,000+…
• L_2_04 — The human settlement of Oceania represents the last major expansion of Homo sapiens across the globe, and the most remarkable feat of maritime exploration in human history.
• L_2_05 — The peopling of the Americas is one of the clearest cases where ancient DNA and archaeology have converged to overturn an older narrative.
• L_2_06 — South Asia harbors one of the most genetically diverse and internally structured population histories of any world region, reflecting deep settlement, repeated admixture, and long periods of…
• L_2_07 — The genetic history of Europe has been revolutionized by ancient DNA, revealing that most present-day Europeans can be modeled at a broad level as mixtures of three major ancestral components…
• L_2_08 — East Asia — comprising China, Japan, Korea, Mongolia, Taiwan, and mainland Southeast Asia — is home to the largest human population concentration on Earth and harbors a complex genetic history…
• L_2_09 — The genetic history of the Americas — from the initial peopling of the New World to the devastating population collapse after European contact — is one of the most intensively studied and rapidly…
• L_2_10 — The domestication of the dog (Canis lupus familiaris) from gray wolves (Canis lupus) represents the oldest known domestication event and one of the most consequential interspecies…
• L_2_11 — The Indo-European question — where was the homeland of the Proto-Indo-European (PIE) language, and how did the Indo-European family spread to encompass languages from Ireland to India? — has…
• L_2_12 — Africa is the cradle of human evolution — the continent where Homo sapiens originated, where the deepest branches of the human family tree diverge, and where the greatest genetic diversity…
• L_2_13 — Island Southeast Asia (ISEA) — the vast archipelagic region encompassing the Philippines, Indonesia, Timor, and the islands between mainland Asia and Australo-Papua — is one of the most…
• L_2_14 — One of the most powerful revelations from ancient and modern DNA studies is that human migration, conquest, and admixture are almost never sex-neutral — they are systematically biased toward one…
• L_2_15 — The Neolithic Revolution — the independent invention of agriculture in the Fertile Crescent (~10,000-8,000 BCE) — was one of the most consequential transformations in human history, and…

DOCUMENT INDEX

WHAT TO EXPECT

Documents in this subfolder follow the project's 4-tier evidence system:

• Tier 1 (Verified): Peer-reviewed, archaeological record, primary texts
• Tier 2 (Credible): Academic, debated but supported by evidence
• Tier 3 (Speculative): Possible but unverified
• Tier 4 (Dubious): No credible source or contradicted by evidence

Tier distribution in this subfolder: 1: 8 docs, 1–2: 1 docs

Each document includes a Quick Summary, tiered claims with specific evidence,

counter-arguments, bibliography, and cross-references to related documents across the corpus.
