Study Explores Evolutionary Link and Metabolic Differences Between Birds and Crocodiles
Crocodiles and birds share a common ancestor from about 250 million years ago, both belonging to the archosauriform group. While birds evolved as warm-blooded creatures with high metabolic rates enabling sustained flight, crocodiles reverted to a cold-blooded metabolism with lower energy output. This metabolic difference explains why crocodiles, despite their shared lineage, cannot fly. The divergence occurred after the group split into two lineages, leading to modern crocodiles and birds respectively.
