Asteroid Impact 66 Million Years Ago Catalyzed Bird Evolution
New research uncovers genetic shifts in bird genomes linked to the mass extinction event that wiped out non-avian dinosaurs.
Overview
- Scientists identified DNA changes in birds correlating with the end-Cretaceous extinction.
- The study used advanced models to detect shifts in avian genomes not previously observable.
- Key traits like body size and parental care evolved rapidly post-extinction.
- Birds' ability to eat seeds may have been crucial for their survival and diversification.
- The findings underscore the long-term evolutionary impact of mass extinctions on biodiversity.
