Ancient DNA from Mayahak Cab Pek is extremely limited: only one individual yields genetic data. That single mitochondrial genome belongs to haplogroup D. Haplogroup D is one of the founding maternal lineages observed across the Americas (commonly reported alongside A, B, C, and X), and its presence at Mayahak Cab Pek is consistent with broader patterns of early Native American maternal diversity.
However, with a sample count of one, any population-level inference is preliminary. The mtDNA D assignment suggests maternal continuity with pan-American founding lineages but cannot resolve finer-scale population structure, migration routes, or local continuity with later Maya populations on its own. No Y-chromosome data are reported for this individual, leaving paternal ancestry uncharacterized.
Genetic data and archaeology together provide a layered narrative: the mitochondrial signal ties the individual to deep New World maternal roots, while the archaeological context shows a lifeway adapted to Belize’s wetlands. Future aDNA from multiple individuals, genome-wide data, and comparisons with later and neighboring samples will be required to test hypotheses about population continuity, admixture, and demographic change in southern Mesoamerica.
