New research by a team of UK scientists has located the site of the massive impact that took place in Scotland 1.2 billion years ago. Roughly one billion years ago, Earth experienced a higher rate of meteorite impact than it does today.
A team of scientists has re-created some of the first steps of life in the lab, testing whether life could emerge on other ocean worlds.
The preservation of trace fossils, suggests that multicellular organisms that could move around to reach food resources may already have existed 2.1 billion years ago, more than 1.5 billion years older than previously thought.
An international team of scientists found evidence that the rock was launched from Earth by a large impacting asteroid or comet. The impact sent material into space, where it collided with the surface of the Moon 4 bil years ago.
Microbes could have performed oxygen-producing photosynthesis at least one billion years earlier in the history of the Earth than previously thought.
A 9.7-million-year-old discovery has left a team of German scientists scratching their heads. The teeth seem to belong to a species only known to have appeared in Africa several million years later.
Could the building blocks for life on Earth have been delivered by meteorites crashing into ponds of water 4 billion years ago?
The researchers argue they have uncovered evidence that there was life on Earth more than 3.95 billion years ago—on a planet that isn’t much more than 4.5 billion years old itself.
Fossils discovered in ancient hot spring deposits in the Pilbara have pushed back by 580 million years the earliest known evidence for microbial life on land.
A new study proves that the Earth and other planetary objects formed in the early years of the Solar System share similar chemical origins – a finding at odds with accepted wisdom held by scientists for decades.
Researchers working in Greenland have found traces of microbial life in our planet's most ancient rocks. The discovery pushes back the oldest evidence of life on Earth by about 220 million years, showing just how habitable our planet was during its earliest stages.
A new study suggests that plate tectonics -- the dynamic processes that formed Earth's mountains, volcanoes and continents -- began about 3 billion years ago. By analyzing trace element ratios that correlate to magnesium content in ancient Earth's crust, the researchers provide first-order geochemical evidence for when plate tectonics first got underway.
