Bray Cave Bronze: Gibraltar EBA

Bray Cave sits on the southern tip of the Iberian Peninsula, where cliffs and sea meet in a landscape long used by humans. Archaeological data indicates human use of Bray Cave during the Early Bronze Age (c. 1900–1400 BCE). The temporal window for the Gibraltar_EBA samples places them in a period of shifting coastal networks, when communities around the western Mediterranean were negotiating new social and economic rhythms driven by metallurgy, long-distance exchange and intensified coastal mobility.

Limited evidence suggests that Bray Cave was part of a mosaic of small settlements and special-use sites along Gibraltar's shore. Material remains in the broader region show continuity with earlier Neolithic and Chalcolithic traditions alongside new Bronze Age influences. This transitional tapestry is visible in pottery styles, raw-material sourcing, and funerary choices elsewhere in southern Iberia — signals that archaeologists bring to bear when interpreting the scant deposits at Bray Cave.

Because the site-specific record is modest, interpretations remain cautious: the Gibraltar_EBA assemblage most reliably testifies to local practitioners living within broader Bronze Age currents rather than to dramatic population replacement. Further excavation and contextual study are required to trace precise cultural lineages.

The genetic picture from Bray Cave is necessarily preliminary: only three ancient individuals are reported (sample count = 3). All three males carry broad haplogroup R on the Y chromosome, while mitochondrial lineages include K, H and T. These results offer a tantalizing but cautious glimpse into male and female ancestries at Gibraltar during the Early Bronze Age (c. 1900–1400 BCE).

Haplogroup R (reported here at the broad level) is widespread in Bronze Age Europe. In other regions, more finely resolved subclades of R (for example, R1b) have been associated with steppe-related migrations and with demographic expansions during the Bronze Age. However, because subclade resolution is not specified for the Gibraltar_EBA males, it is scientifically inappropriate to assert a direct steppe origin; the data are compatible both with incoming male-biased lineages and with regional continuity of R-bearing groups.

Mitochondrial haplogroups K, H and T reflect maternal diversity. Haplogroup K is often linked to Neolithic farmer ancestries in Europe, H is common and widespread across later European populations, and T appears intermittently through Neolithic and Bronze Age contexts. Taken together, the mix of maternal and paternal signals suggests a community with diverse maternal roots and a more homogeneous paternal record — but again, with only three samples this remains a tentative pattern.

Archaeogenetic interpretation must stress uncertainty: low sample count (<10) and limited genomic resolution constrain broad claims. Future sampling and genome-wide analyses are required to robustly connect Bray Cave inhabitants to regional ancestry gradients, admixture events, and mobility corridors along the western Mediterranean.
