The evolution of birds is a fascinating journey from small, feathered dinosaurs to the diverse species we see today. Key milestones include the feathered theropod ancestors and the earliest known bird, Archaeopteryx.
- Feathered Dinosaurs (150 million years ago): Small, carnivorous dinosaurs with feathers, like Archaeopteryx.
- Early Birds (145-66 million years ago): Transition from small theropods to more bird-like forms.
- Diversification (66 million years ago - present): Explosive speciation leading to modern birds, with adaptations for flight, water, and land.
Pro tip: Birds evolved from a common ancestor through gradual changes in morphology and behavior over millions of years.
