The Log-Coffin People of Pang Mapha

In the limestone country of Pang Mapha, in Thailand's far northwest, people carved coffins from single teak trunks and set them in more than forty caves and rock shelters between about 2,300 and 1,000 years ago. Twelve of the Log Coffin people are gathered here, from Yappa Nhae 2 and the Tham Lod rockshelter, dated between roughly 150 and 400 CE. Their ancestry combined three sources: about 13 percent from Hoabinhian hunter-gatherers, 43 percent from southern East Asian farmers and 44 percent related to the Upper Yellow River. Close relatives were laid in the same cave, while more distant kin link caves in different valleys, a web of related communities across the hills. Among living peoples they sit closest to the Lawa, Mon and Karen. The remains were studied under Fine Arts Department permits and returned to it, with the Tham Lod community kept informed of the findings.

The genome-wide data behind this entry was published in Genomic portrait and relatedness patterns of the Iron Age Log Coffin culture in northwestern Thailand.

Every Ancestry Map includes the free Notable Matches lens: your coordinates are compared to every sequenced member of every catalog entry, and the distance to the closest member is reported, a Euclidean distance in the same 25-dimensional space the Distance lens uses. Because these are a small group of real individuals, not a population average, distances naturally run larger than population distances. That is expected, not a poor result. And one thing is never claimed: a small distance means similar ancestry composition, not that the Log-Coffin People of Pang Mapha are your ancestor.

• 01

  Who were the Log-Coffin People of Pang Mapha?

  The Log-Coffin People of Pang Mapha (c. 150-400 CE, Pang Mapha district, Mae Hong Son, Thailand) are one of the Iconic discoveries entries in our Notable Matches catalog, represented by 12 sequenced ancient genomes published in the study "Genomic portrait and relatedness patterns of the Iron Age Log Coffin culture in northwestern Thailand".

• 02

  What does "matching" the Log-Coffin People of Pang Mapha mean?

  Your Global25 coordinates are compared to the entry's sequenced members and the distance to the closest one is reported, a Euclidean distance in the same 25-dimensional reference space the Distance lens uses. A notable entry is one person or one small burial group, not a population average, so distances naturally run larger than population distances.

• 03

  Are they my ancestor?

  No, and no DNA test can show that. A small distance means your genome sits near theirs in a shared reference space: similar ancestry composition, not descent. Ancestrify never claims a notable individual is your ancestor or relative.

  How do I see my own distance to the Log-Coffin People of Pang Mapha?

  Notable Matches is a free lens on every Ancestry Map, never sold separately. Order Ancestry Map, our Global25 analysis (29.99 EUR), and your report ranks your coordinates against the full catalog, with a portrait, dossier and map for every entry. The public demo shows the lens with example data.
