Research unravels mystery of how early animals survived ice age

How did life survive the most severe ice age? A McGill University-led research team has found the first direct evidence that glacial meltwater provided a crucial lifeline to eukaryotes during Snowball Earth, when the oceans ...

Did last ice age affect breastfeeding in Native Americans?

The critical role that breast feeding plays in infant survival may have led, during the last ice age, to a common genetic mutation in East Asians and Native Americans that also, surprisingly, affects the shape of their teeth.

A habitable environment on Martian volcano?

(Phys.org) —Heat from a volcano erupting beneath an immense glacier would have created large lakes of liquid water on Mars in the relatively recent past. And where there's water, there is also the possibility of life. A ...

Research shows how life might have survived 'snowball Earth'

Global glaciation likely put a chill on life on Earth hundreds of millions of years ago, but new research indicates that simple life in the form of photosynthetic algae could have survived in a narrow body of water with characteristics ...

'Super-river' formed the English Channel

(PhysOrg.com) -- A team of Anglo-French scientists studying sedimentary deposits in the Bay of Biscay have concluded that Britain and France were separated by a "super-river" during three periods of glaciations, and they ...
