Genomic selection in European cattle breeding: systemic erosion of genetic diversity amid industrial efficiency gains
Original framing: “Impact of genomic selection on genetic diversity in five European cattle breeds” — Phys.org
Smallholder farmers and pastoralists, who maintain 70% of the world’s livestock genetic diversity, are systematically excluded from genomic selection programs. Their knowledge of local breeds and adaptive traits is dismissed as 'unscientific,' despite evidence of its efficacy. The narrative’s focus on 'cosmopolitan breeds' reflects a bias toward industrial actors, erasing the contributions of marginalized communities to global biodiversity.
The erosion of genetic diversity in European cattle breeds is not an accidental byproduct of progress but a structural outcome of industrial livestock systems that prioritize short-term yield over long-term resilience.
This pattern mirrors historical precedents, from the Green Revolution to the displacement of indigenous breeds by colonial livestock systems, revealing a global narrative of biodiversity sacrifice for efficiency. The marginalization of pastoralist communities and their knowledge systems exacerbates the problem, as their stewardship of diverse breeds is systematically undervalued. Yet, as Hermes would remind us, the 'chaos' of genetic diversity is the very foundation of adaptability—a truth obscured by the solemnity of industrial metrics. The solution lies in reversing this power imbalance: by centering indigenous knowledge, regulating genomic selection to mandate diversity safeguards, and incentivizing agroecological systems, we can transform livestock breeding from a driver of homogenization into a model of resilience. The stakes are high, for in the genetic narrowing of cattle, we see a microcosm of the broader ecological and cultural impoverishment wrought by unchecked industrialization.
