Briefings

A 2026 study published in PLOS One by researchers at Universidade de Brasilia and colleagues found that the complex ridge patterns on monkey feet and palms vary between individuals, mirroring human fingerprint uniqueness. This finding suggests a biological mechanism for individual identification in primates, though the study is limited to three specific monkey species.

Key points

• Three monkey species exhibit unique ridge patterns on feet and palms, similar to human fingerprints.
• The study was conducted by Juliana Vieira Flores Sales and colleagues at Universidade de Brasilia.

Context

This research provides biological evidence for individual identification in primates, potentially aiding in forensic applications or understanding primate genetics. The study is published in an open-access journal.

Limitations

The evidence is limited to three specific monkey species; the study does not cover all primate species or humans. Results are observational and do not include causal claims or forecasts.
