Bird evolution didnt happen steadily: AI reveals 45 million years of climate-driven changes in skeletons

Bird skeletons reveal evolutionary history shaped by climate shifts and environmental upheaval. Artificial intelligence analyzed thousands of museum specimens for anatomical measurements. Researchers found rapid anatomical changes occurred during ancient cooling periods. Evolutionary rates also slowed during other significant geological and environmental shifts. This study highlights how environmental variability influences bird body form evolution.
