Abstract excerpt

A central paradox in evolutionary biology is the rarity of asexual reproduction, often attributed to developmental constraints and long-term costs. Yet, fissiparous asexuality-where animals split and regenerate-is widespread among planarians, hinting at genomic features predisposing them to asexuality. We investigate the genomic underpinnings and evolutionary consequences of asexuality in the planarian Schmidtea...
