Adam's Bridge chronology and lower sea levels

Did the India-Sri Lanka land bridge disappear just before Europeans arrived, and is there more information about it?

The recent-collapse claim is disputed; different recollections suggest much older submergence and later partial exposure, without settling the chronology.

A viewer recalls a claim that the land bridge disappeared only shortly before Europeans arrived, but Alex does not recognise that as his account. He recalls a much older loss of the connection, while another participant gives an estimate of about 7,000 years. The surviving islands and shallows remain visible and important in local geography and Hindu tradition. A further contribution proposes that lower sea levels during the Little Ice Age made parts traversable again. The exchange offers several recollections without establishing a single chronology.
