Spontaneous mutations arise “naturally” WebApr 6, 2024 · Spontaneous mutations are the ultimate source of novel genetic variation on which evolution operates. While mutation rate is commonly described as a single parameter in evolutionary models, it is increasingly evident that mutation rates vary due to changes in the rate of distinct nucleotide substitutions.
