Abstract: The evolution of human longevity still remains a curious puzzle. Here I provide some new perspectives on the why and how of longevity over the course of human evolution, relying on the anthropological study of subsistence societies as an imperfect lens for gaining insight. I argue that our evolved human lifespan is about seven […]
Abstract: When we contemplate how biodiversity is changing, we often focus on the species we have lost entirely. But while we have yet to lose a single bird species to our rapidly changing climate, birds and other creatures are currently adapting and responding in myriad ways. Across the world, species are shifting their geographic distributions, […]
Abstract: A long-standing goal within the field of evolutionary genomics has been to understand how genomic and phenotypic differences between human populations arise. High-altitude environments offer a natural experiment to study this question, as these environments impose a number of selective pressures, the most severe of which is high-altitude hypoxia. Human populations residing across the […]
Abstract: Organisms that develop under adversity often differ from their peers in stress physiology, behavior, and reproductive timing. Life history frameworks offer a powerful lens for making sense of this variation, proposing that these differences reflect developmental responses calibrated to early environmental conditions. Yet the mechanistic pathway connecting early adversity to physiological changes to behavioral […]
