Earth, Glaciers and Complex Life

Glaciers ‘bulldozed’ snowball Earth and changed ocean chemistry, paving the way for complex life, scientists say
Glaciers once inched toward the sea, gouging rocks. When the ice masses melted, they infused oceans with nutrients that may have shaped how life evolved, a study found.
Giant glaciers pulverized Earth's ancient rocks, setting the stage for complex life
Imagine floating in space, gazing on a frozen white orb. The ball hangs in the void, lonely and gleaming in the light from its star. From pole to equator, the sphere is covered in a thick crust of ice.
Ancient Glaciers May Have Given Rise To Complex Life On Earth
Around 700 million years ago, Earth was a very different planet—gripped by extreme deep freezes during the Cryogenian period. Enormous glaciers, kilometers thick, stretched across vast regions, turning much of the planet into a frozen wasteland.
