While the devastating asteroid impact 66 million years ago wiped out most dinosaurs, one group not only survived but thrived: birds. In a recent podcast, Prof Steve Brusatte, a palaeontologist at the University of Edinburgh, discusses his new book The Story of Birds, which traces the evolutionary journey from feathered dinosaurs to modern birds.
The Origin of Feathers
Brusatte explains that feathers first evolved not for flight but for insulation and display. Over millions of years, these structures became more complex, enabling some dinosaurs to glide and eventually fly. This adaptability was key to their survival.
Surviving the Asteroid
When the asteroid struck, it caused mass extinction. However, small, feathered dinosaurs that could fly or burrow had a better chance. Birds, being warm-blooded and able to find food in devastated landscapes, managed to endure.
Lessons for the Future
Brusatte highlights that birds' extreme adaptability offers hope. By studying their evolution, we can understand how species cope with environmental crises. He suggests that protecting bird habitats today is crucial for their survival amid climate change.
