Water was once widespread on Mars, data from a Nasa spacecraft shows, raising the prospect that the Red Planet could have supported life. ... Rocks of this age have largely been destroyed on Earth by plate tectonics. They are preserved on the Moon, but were never exposed to liquid water. So rocks containing phyllosilicates on Mars preserve a unique record of watery environments in the early Solar System, some of which could have been...

There is evidence that life evolved in the deep sediments. ... There is clear evidence that life existed more than 3.8 billion years ago. Although, for there to be a big enough biomass for us to detect it in the rocks, it must have been evolving long before that. ... The normal view of life on Earth is that the majority of life is on the surface, fuelled by sunlight. And you don't expect a large population - even bacteria - to survive...

Prehistory is a term used to describe the period before recorded history.

The notion of limiting historical study to a roughly 5000-year span, out of a possible few million years of human existence, and of only those few world cultures that left written records, is hardly tenable. It remains a possibility that somewhere between the origins of intelligent humanoids and first preserved artifact, or indeed in the vast periods on the geologic time scale, long before what we call ancient history, there existed...

Life on Earth may have driven the evolution of the planet itself. The idea is that ancient microbes provided the chemical energy to create the Earth's continents - a nod to the Gaia hypothesis, in which life helps create the conditions it needs to survive. The theory would solve the puzzle of why the Earth's continental crust appeared when it did, and explain the presence of granite, a substance not found anywhere else in our...

Analysis of early human-like populations in southern Africa suggests females left their childhood homes, while males stayed at home. An international team examined tooth samples for metallic traces which can be linked to the geological areas in which individuals grew up. The conclusion was that while most the males lived and died around the same river valley, the females moved on. Similar patterns have been observed in chimpanzees, bonobos...
