Hundreds of millions of years before there was a chicken or an egg to debate, the first complex animals were evolving in parallel with Earth's rising oxygen levels.
Yale researchers have provided a new explanation for why Earth's early climate was more stable and warmer than it is today.
The discovery of Earth's youngest-ever banded iron formation is changing how scientists understand the evolution of complex life, according to a study by University of Alberta geologists.
Some of the earliest complex organisms on Earth—possibly some of the earliest animals to exist—got big not to compete for food, but to spread their offspring as far as possible.
In the past two decades, NASA spacecraft have identified potentially habitable environments throughout the solar system and beyond. Spacecraft on Mars have found evidence that lakes and streams once covered the planet, protected ...
Ancient microbes may have been producing oxygen through photosynthesis a billion years earlier than we thought, which means oxygen was available for living organisms very close to the origin of life on earth. In a new article ...
A team of American Museum of Natural History researchers has created a computational model capable of predicting whether or not organisms have the ability to "eat" other cells through a process known as phagocytosis. The ...
In popular culture, asteroids play the role of apocalyptic threat, get blamed for wiping out the dinosaurs - and offer an extraterrestrial source for mineral mining.
Complex life, as we know it, started completely by chance, with small strands of molecules linking up, which eventually would have given them the ability to replicate themselves.
Research led by The Australian National University (ANU) has solved the mystery of how the first animals appeared on Earth, a pivotal moment for the planet without which humans would not exist.
