Results support the plasticity/constraint model: early-life stress constrained later survival and resilience, showing how diet, demography & ecology shaped Indigenous Canarian life histories. #islandarchaeology #dentalanthropology #humanadaptation

🧑‍🤝‍🧑 Sex differences: males consistently showed higher LEH than females—supporting the male vulnerability hypothesis.
Those with LEH were underrepresented in older age groups → early stress reduced survival odds.

Findings reveal striking differences in stress prevalence across islands. La Palma showed the lowest LEH prevalence. Its mixed subsistence. buffered stress.Gran Canaria & Tenerife had higher LEH, linked to agricultural reliance and its vulnerabilities.

🦷 This paper explores how early-life stress shaped Indigenous populations of the Canary Islands (2nd–15th c. CE). The team studied 409 individuals from six islands, focusing on linear enamel hypoplasia (LEH)—a marker of childhood stress episodes recorded in teeth.
