ZB_2_23 — Cephalopod Intelligence and Distributed Cognition

Cephalopods — octopuses, cuttlefish, squid, and nautiluses — represent one of evolution's most extraordinary experiments in intelligence, having diverged from the vertebrate lineage approximately 530 million years ago ye

ZB_2_05 — Aging, Longevity, and the Biology of Death

Why do organisms age and die? This question — one of the oldest in human inquiry — has yielded remarkable molecular answers in recent decades. Leonard Hayflick's 1961 discovery that human cells have a finite replicative

ZB_1_11 — Predator-Prey Dynamics and Coevolution

Predator-prey dynamics are among the most fundamental processes structuring ecological communities, driving evolutionary arms races, and shaping biodiversity. The Lotka-Volterra equations (Lotka, 1925; Volterra, 1926) pr
