The origin of life on Earth could be much simpler than thought
The origin of the first living molecules on our planet has long been debated. However, recent experiments are revealing new ...
Maybe the first life on Earth was part of an 'RNA world.' Artur Plawgo/Science Photo Library via Getty Images How life on Earth started has puzzled scientists for a long time. And it still does.
New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...
Scientists refine the timeline of sponge origins, showing soft-bodied ancestors likely evolved later than some chemical ...
A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests ...

Earth's Early Oxygen May Have Come From Rocks — And It Could Have Big Implications For Life in Space
One broken piece of quartz in a physics lab could shed light on the history of life on Earth and the search for other habitable worlds. Today, most life as we know it depends on oxygen. Specifically, ...
IMAGE: A new study by CU-Boulder researchers indicates a thick organic haze shrouding Earth several billion years ago was similar to the one now hovering over Saturn’s largest moon, Titan. University ...
Four billion years ago, our then stripling sun radiated only 70 to 75 percent as much energy as it does today. Other things on Earth being equal, with so little energy reaching the planet’s surface, ...
