Why did some ancient snakes possess functional legs 90 million years ago?
In short: This video examines the mysterious origins of snakes, focusing on the fossil record of limbed species like Najash. It explores the evolutionary puzzle of how snakes transitioned from legged creatures to the limbless reptiles we recognize today.
The fossil record reveals that snakes were not always legless. Approximately 90 million years ago, the ancient snake Najash walked on legs, challenging our understanding of snake evolution. Despite these discoveries, the precise origins of snakes remain a subject of significant scientific debate.
Researchers continue to investigate the lineage of these limbed reptiles to determine how and why they lost their appendages over time. By analyzing specimens like Najash, paleontologists hope to clarify the evolutionary path that led to modern snake morphology.
