random mutation
Unplanned DNA change
Random mutation refers to spontaneous, unpredictable changes in genetic material—the molecular errors that occur during DNA replication or from environmental factors like radiation.
In evolutionary biology, random mutations provide the raw material for natural selection: most are neutral or harmful, but occasionally one confers an advantage.
The term emphasizes that mutations arise without direction or purpose—nature doesn't "aim" for beneficial changes.
The antibiotic resistance emerged through random mutation, not design.
