Fly Genitalia Study Shows How Evolution Invents New Body Parts
Original: A ‘Male Organ’ for Flies Reveals How Evolution Invents New Body Parts
Researchers at UC Davis report that a male reproductive structure in flies reveals how evolution can generate entirely new body parts. The work suggests novel organs can arise through the repurposing of existing developmental genes and tissues rather than from scratch. The findings are drawing attention among biologists interested in how novel traits originate over evolutionary time.
Why now: New research from UC Davis offers a mechanistic explanation for a long-standing question in evolutionary biology: how new organs emerge.
