Over the past century, it has faced severe threats from overharvesting, pollution, and catastrophic mass mortality events. This study analysed 119 mitochondrial COI gene sequences from historical (1700s, 1920s, 1970s, 1990s) and modern (2000s) samples, including survivors of recent mass mortality crises. We standardised a protocol to extract DNA from ancient byssus samples over a century old and dated the emergence of the mitochondrial lineages of Pinna nobilis, uncovering its evolutionary history in unprecedented detail. Our findings suggest two main temporal origins for the species' genetic variation: (i) a group of modern lineages directly descended from Pinna nobilis early ancestors originating 2.5 mya, and (ii) a large group derived from the first Pleistocene radiation of the species, approximately 1.5 mya. Importantly, our research depicts the evolutionary response of Pinna nobilis to three major challenges in the last century: human overexploitation, pollution, and environmental changes. Our results highlight the species' remarkable resilience, likely mediated by Pleistocene genetic traits, whose persistence over time mainly depends on the maintaining of a high effective population size to ensure successful recruitment. |
