[Explainer] The Pacific Was Not a Straight Line: How Palau Genomes Rewrite the “Out of Taiwan” Story

Humans reached the Pacific nearly simultaneously ~3,000 years ago — but Palau's first settlers were already admixed, unlike Vanuatu's "East Asian first, Papuan later" sequence. The Out-of-Taiwan map needs redrawing.

[Explainer] When 20 STRs Are Not Enough: Why Both Forensics and Ancient DNA Turn to 90,000 SNPs

~20 STRs suit parent–child testing but fail on degraded bone and cousins. Typing ~95,000 short-fragment SNPs fixes both — and forensics and ancient DNA both swear by the petrous bone.

[Explainer] mtDNA Haplogroup D4h: The Maternal “Molecular Clock” in Donghulin’s 11,000-Year-Old Woman

Two Donghulin individuals share mtDNA haplogroup D4h on different branches, splitting ~13–14k years ago. Why the matrilineal mitogenome is the first genetic code rescued from millennia-old bone powder.

[Explainer] Where Does Your Y Chromosome Come From? Reading East Asian Paternal Migrations Through O, N, C and F

The Y chromosome passes only father to son — a paternal molecular clock. A plain-language tour of O1, O2, N, and C/D/F, and how a study of ~18,000 samples redraws East Asian male migration.

[Explainer] The Cave-Burial Ancestors: How Ancient DNA Links Guangxi to Today’s Kra–Dai and Hmong–Mien Peoples

Were the cave-burial people of Guangxi the ancestors of today's Kra–Dai and Hmong–Mien speakers? Ancient DNA says yes — and reveals that cross-border Hmong–Mien kept more southern ancestry than their kin inside China.

[Explainer] How DNA Companies “Reconstruct” Ancestors You Never Met — and Where It Falls Short

Reconstructing ancestors isn't magic: it stitches together chromosome segments shared across many descendants. Here is how it works, how it differs from ethnicity estimates, and why Eurocentric databases leave East Asian users with gaps.

[Explainer] Beijing 11,000 Years Ago: The “Forgotten Ancient Northerners” in the Donghulin Genome

Why does the DNA of a Donghulin woman from 11,000 years ago force a rewrite of northern East Asian prehistory? A plain-language guide to "deeply divergent lineages" and the slow transition to millet farming.
