What geological time frame is suggested by molecular studies for the initial diversification of Scolecophidians?
Answer
As far back as 150 million years ago during the Jurassic and Cretaceous periods
Molecular evidence points to a profound antiquity for the Scolecophidians, which encompass blindsnakes and threadsnakes. The initial diversification event that established this ancient lineage of snakes is suggested to have begun approximately 150 million years ago. This timing correlates precisely with the geological epoch when the supercontinent Gondwana began its division into its eastern and western continental sections, setting the stage for geographic separation of the early snake groups.
