Definition: The term "antievolutional" refers to a scientific perspective that acknowledges evolution as incomplete, suggesting more complex or fundamental processes may underlie life than initially perceived. It emphasizes the importance of understanding complexity within natural systems beyond simplistic biological classification. The term was first used in the 1970s, when it became widely accepted within scientific circles. Definition: "Antievolutional" is a science fiction term used to describe scenarios where fundamental processes or beliefs are so far removed from what scientists consider normal that they have been deemed "antiviral." It suggests these processes cannot be fully explained by existing biological explanations and can instead explain complex, unforeseen systems. The term often refers to an era of science, culture, and philosophy in which ideas about life beyond human biology are considered highly suspect or even subsumed into the realm of scientific speculation. The concept was particularly popularized by J.K. Rowling's 1996 novel "Harry Potter" when it was published, where the term is used to describe a fictional time period following the events of the previous Harry Potter series.
