Geologists have discovered the first ancestor on the family tree that contains most animals today, including humans. The wormlike creature, Ikaria wariootia, is the earliest bilaterian.
Scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia 2,2 billion years ago, and coincided with the end of a global deep freeze known as a Snowball Earth.
A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
Called the "frozen dragon of the north," a new species of flying dinosaur, Cryodrakon boreas, has been discovered in Canada. The pterosaur is thought to have had the wingspan of a small airplane.
Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn caused diversification.
Researchers have discovered a remarkably complete 3.8-million-year-old cranium of Australopithecus anamensis at Woranso-Mille in Ethiopia. Due to its rare state, the researchers identified never-before-seen facial features in the species.
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.
