World atavism

"World Atavism" by Edmond Hamilton is a science fiction novel written in the early 20th century. The book explores the concept of evolutionary biology through a dramatic narrative, detailing how humanity faces a backward slide into primitive, savage forms due to a disruption of the evolutionary vibrations emitted by the sun. The storyline underscores themes of scientific discovery, the fragility of civilization, and the potential for regression in the face of existential threats. The narrative follows Dr. Allan Harker and his colleague Dr. Raymond Ferson, who become embroiled in a crisis when Dr. Howard Grant, a renowned biologist, vanishes after proclaiming that he has discovered the cause of evolution. As violent crimes and inexplicable accidents escalate worldwide, Harker and Ferson deduce that Grant has manipulated the sun's evolution vibrations, causing a global atavism that returns humanity to its primal state. In a race against time, they attempt to locate Grant and stop the catastrophe, ultimately leading to a poignant but distressing climax that raises questions about human progress and the cyclical nature of civilization. The book concludes with Harker’s reflections as he faces his fate, highlighting both a sense of despair and a glimmer of hope for the future of life on Earth.
