What is the molecular clock estimation for the origin of crown snakes, sometimes called "one blind grandpa"?

Answer

Around 100 to 150 million years ago

Genetic work studying the immediate ancestry of extant snakes suggests that the majority of living snakes share a surprisingly recent common ancestor, informally termed the "one blind grandpa." Molecular clock estimations utilized by the scientific community place the origin or diversification event for these crown snakes within a specific time frame. Current estimations place this critical origin event around 100 to 150 million years ago. This finding implies a rapid diversification following an earlier extinction event or environmental shift, leading to the successful lineage that includes nearly all modern snakes, even though fossil evidence for the absolute earliest forms remains scarce.
