Buried inside ancient grains of rock salt, a team of geologists has discovered traces of a breathable, animal-friendly atmosphere. If confirmed, the finding will push back the rise of oxygen on Earth hundreds of millions of years, raising new questions about the evolution of complex life both here and beyond our solar…
About 600 million years ago, life on Earth was pretty much just a homogeneous bunch of simple, soft-bodied species. But in an evolutionary blink of an eye, that all changed. A longstanding geological mystery could explain why our distant ancestors suddenly developed skeletons.
Researchers have discovered 650-to-640 million-year-old sponge fossils at Australia's Flinders Ranges. These fossils predate the oldest known animal fossils by 90 million years and antecede the blossoming of life during the Cambrian Explosion ~524 million years ago.
Weirdest science art we've seen lately: artists working with the Institute for Figuring have recreated the hyperbolic surfaces of undersea reefs using the plastic garbage that is helping to kill them — plus a lot of crocheting as well. Artworks include "The Ladies' Silurian Atoll" and "Cambrian Explosion Reef."
