Archaic ancestry explorer

Trace Neanderthal and Denisovan markers in your genome

Upload AncestryDNA, 23andMe, or FTDNA raw data to quantify archaic signal rates, compare against global reference panels, and surface standout variants that distinguish your archaic ancestry.

Neanderthal and Denisovan DNA Calculator

Small segments of Neanderthal and Denisovan DNA are present in many people today, especially across parts of Eurasia. These segments can be used as signals to compare your genome to curated regional references built from modern global cohorts.

This calculator reads your raw data and measures how often your allele states match known archaic-informative marker positions. Scores are computed against Genostruct’s regional references and summarized by world regions. As additional samples are incorporated or regional panels are refined, reported ranges may shift slightly.

Quick answers

What does this calculator measure?

It checks how often your allele states match archaic-informative markers derived from Neanderthal and Denisovan references.

Which raw data formats work?

Upload the ZIP, TXT, or CSV exports you download from 23andMe, AncestryDNA, or FTDNA.

Upload your AncestryDNA, 23andMe, or FTDNA raw data

We read the markers required for archaic ancestry modelling. Works with AncestryDNA, 23andMe, and FTDNA exports.

The file is analysed securely in one session and never persists on our servers.

Looking for other providers? Share a raw export and we’ll assess marker overlap for future support.

Reference-calibrated

Your hit rates are benchmarked against population cohorts from published studies, expressing how rare your archaic markers are.

Transparent markers

We highlight the exact variants, dosages, and expected archaic alleles that contribute to elevated scores for each group.

Instant interpretation

Results render immediately after upload with no account creation required.

Archaic signal FAQ

Answers to the most common upload, scoring, and privacy questions about this calculator.

How do I get my raw data file?

Export it from your 23andMe, AncestryDNA, or FTDNA account and upload the ZIP/TXT/CSV here.

Is this a percentage of ancestry?

The score reflects match rates at archaic-informative markers, not a direct ancestry percent. Higher scores simply mean more of your allele states match the archaic-assumed variants at those informative SNPs within our reference framework.

Which regions tend to show stronger signals?

Some Eurasian groups commonly show stronger archaic signals than other world regions in our references.

What references are used?

Genostruct uses internally curated modern percentile references. Current reference regions include Northern and Western Europe (e.g. Scandinavian, Scottish, and French samples), West Asia, East Asia, Australian Aboriginal populations, and Mbuti. The archaic-informative markers used for Neanderthal and Denisovan signal modelling were originally defined using comparisons against Mbuti. As regional references are expanded or refined, percentile ranges may shift slightly.
