The term "accumulate mutations" refers to the gradual build-up of errors or changes in DNA over time. Some synonyms for this process include "collect mutations", "amass genetic variations", and "gather genetic mutations". These terms all suggest a gradual process of change that occurs over time, perhaps in response to environmental factors or random errors in DNA replication. Other synonyms for "accumulate mutations" might include "accumulate genetic defects", "build up genetic errors", or "accumulate DNA damage". Ultimately, the process of accumulating mutations can lead to the evolution of new species or the development of genetic disorders in humans and other organisms.
