The video explores the possibility that Earth once had a ring, similar to Saturn's, which may have played a significant role in the planet's biodiversity. During the Ordovician Period, Earth experienced a sudden increase in biodiversity, possibly linked to a meteorite shower from a disintegrated asteroid. The Roche limit explains how such a ring could form. Researchers hypothesize that the ring's debris fell to Earth, impacting the climate and driving evolutionary changes. This ancient ring might have contributed to the diversification of life, shaping the planet's history.
