Neutrality proposed as evolution's null hypothesis
Original: Neutrality as the null hypothesis of biological evolution
A Nature publication argues that neutrality should serve as the null hypothesis in biological evolution research, framing debates over how much genetic change is driven by neutral processes versus selection. The piece revisits the long-running discussion sparked by Motoo Kimura's neutral theory, prompting researchers to weigh when claims of adaptation are justified and when random drift offers a simpler explanation.
Why now: Researchers are debating how evolutionary biology should frame its default assumptions when testing claims of natural selection.
