Скачать или смотреть The Sun's Deadly Rays: The Unexpected Spark for Life on Earth? A Deep Dive into Cosmic Chemistry.

The established narrative often positions intense early Earth ultraviolet radiation as a purely destructive force for nascent biology. However, fascinating counter-theories suggest something entirely different was at play. Consider the role of Polycyclic Aromatic Hydrocarbons—substances that may have served as the planet's original pigment, absorbing and cleverly dissipating lethal UV energy. This protective layer shields the very short, simple polymers assembling in the primordial soup, potentially enabling UV-driven chemistry to actually forge ready-to-go nucleotides. The discussion shifts the focus back to the 'warm little pond' concept, envisioning a pool of sludge turning steadily black as these early chemical systems develop, marking the critical transition where mere geology gives way to the first capture of energy and the dawn of evolution. It is a compelling argument for the sun's unexpected role in kick-starting existence.
