Low Solar Activity, Winter Flu Conditions, Pandemics and Sex Wars: A Holistic View of Human Evolution

Roy Barzilai


The current spread of coronavirus has caught our modern world by surprise, which leads to widespread panic, fear and confusion. However, if we view the unfolding of these events from a scientific historical perspective of past human evolution, we may discover the reoccurring patterns of the environmental conditions that give rise to such epidemics. Hence, we can figure out better methods to prepare and react to the infectious agents that spread diseases that have shaped the course of human history before. Here, I propose a holistic view of human evolution, with an interdisciplinary approach that studies how cyclic variation in solar UV energy affects the evolution of viruses and shapes the symbiotic dynamics of human life on earth.
