Summary
Host Emily Kwong interviews science journalist Roxanne Comsey about the constant genetic mutations occurring in human cells. They discuss how modern sequencing reveals this internal diversity, linking mutations to health, behavior, and spontaneous corrective events. The conversation also challenges assumptions about parental age, noting that most new mutations in offspring originate from sperm rather than eggs.
