INTRO: Long before complex life crawled from the oceans to make itself at home on dry land, Earth endured an ice age like no other. On two separate occasions, fingers of ice stretched far from the poles, turning the planet into a frozen wasteland.

Just how far glaciers reached has been a matter of debate. Some contend the runaway deep freeze extended across all latitudes, completely coating Earth in a thick coat of ice as far as the equator.

Others argue equatorial latitudes may have been relatively ice-free. Evidence buried in the fossil record also suggests there might have been patches of exposed ocean, enough for oxygen and light to permeate the waters and allow complex life to flourish.

In that vein, a new study by researchers from China and the UK is the latest to suggest 'Snowball Earth' wasn't completely covered in ice – and might have even exhibited habitable open-ocean conditions far away from the equator... (MORE - details)
