The human brain, unlike the rapid pace of cultural and technological change, is the product of long evolutionary processes shaped over millions of years within a hunter–gatherer context. Most of our cognitive, emotional, and social mechanisms evolved for life in small, mobile, and environmentally embedded groups—not for existence in today’s dense, complex urban societies. This mismatch between our evolved mind and the modern world underlies many of the behavioral patterns and psychological conflicts characteristic of contemporary life.

Drawing on findings from evolutionary psychology, neuroscience, and behavioral archaeology, this talk explores how ancient adaptations—such as fear, aggression, empathy, food preferences, and social tendencies—manifest themselves in modern contexts, often in maladaptive ways. For instance, the ancestral craving for sugar and fat, once a survival strategy in food-scarce environments, now contributes to global health issues; likewise, our deep-seated desire for social validation finds new expression in the dynamics of social media.

The goal of this talk is not to romanticize the past but to illuminate the evolutionary legacy that continues to shape human behavior. By understanding the prehistoric architecture of our minds, we can better interpret our motivations, biases, and challenges in the modern age. To understand the hunter–gatherer mind, ultimately, is to understand ourselves.

چکیده:

We investigate the sensing capacity of non-equilibrium dynamics in quantum systems exhibiting Bloch oscillations. By focusing on the resource efficiency of the probe, quantified by quantum Fisher information, we find different scaling behaviors in two different phases, namely localized and extended. Our results provide a quantitative ansatz for quantum Fisher information in terms of time, probe size, and the number of excitations. In the long-time regime, the quantum Fisher information is a quadratic function of time, touching the Heisenberg limit. The system size scaling drastically depends on the phase changing from quantum-enhanced scaling in the extended phase to size-independent behavior in the localized phase. Furthermore, increasing the number of excitations always enhances the precision of the probe, although, in the interacting systems the enhancement becomes less eminent than the non-interacting probes. This is due to the induced localization by increasing the interaction between the excitations. We show that a simple particle configuration measurement together with a maximum likelihood estimation can closely reach the ultimate precision limit in both single- and multi-particle probes.
