Quizplus · Accepted Answer

The end of the last snowball Earth phase is estimated to have occurred around 635 million years ago, which is consistent with the beginning of the Cambrian period (541 million years ago). The Cambrian explosion refers to the rapid diversification of multicellular organisms during this period, suggesting a connection between the end of the snowball Earth phase and the emergence of complex life forms. There is no direct evidence to suggest that the end of the snowball Earth phase was linked to the appearance of modern hominids or the dinosaurs, and migration of life from the oceans onto land occurred much later in Earth's history.
