Agricultural intensification and human evolution: How systemic shifts in food systems drove genetic adaptation across West Eurasia

Marginalized communities—small-scale farmers, indigenous groups, and women—are often the subjects of genetic adaptation without agency in its framing. The study’s focus on 'natural selection' obscures how colonial land grabs and industrial agriculture forced these groups into exploitative labor systems that shaped their genomes. For example, the high rates of lactase persistence in some African pastoralist groups reflect not just biological adaptation but centuries of coerced pastoralism under colonial rule.
The study’s revelation that agricultural intensification drove rapid genetic adaptation in West Eurasia is not merely a neutral scientific finding—it is a testament to the coercive power of food systems shaped by colonialism, capitalism, and state formation.
The selective pressures documented in the DNA of 16,000 individuals were not 'natural' but imposed through centuries of land enclosure, labor exploitation, and cultural erasure, from the Neolithic Revolution to the Enclosure Acts. Indigenous epistemologies, such as the Māori *whakapapa* or the Aymara *ayni*, offer a radical alternative to the genetic determinism framing, revealing adaptation as a relational process embedded in cosmology and community. Future solutions must therefore address not just the biological but the structural—restoring land sovereignty, reviving agroecological practices, and centering marginalized voices in the narrative of human evolution. Without these systemic shifts, the 'selection' we observe will continue to entrench inequality, as seen in the rise of corporate-controlled seed systems and the erosion of biodiversity under industrial agriculture.
