World atavism

A first-person account by a university scientist recounts a colleague's claim that an otherwise unknown solar vibration controls evolutionary change. The revelation sparks heated scientific debate and experimental efforts to isolate and manipulate that vibratory force. The narrative alternates between laboratory exposition and observations of the city's altered appearance as researchers test the hypothesis, exploring consequences when cosmic influences are treated as manipulable. Themes include the interplay between cosmic forces and terrestrial life, the responsibilities of scientific inquiry, and the social fallout that follows once a purported mechanism of evolution becomes a subject of human intervention.
