YAHOO NEWS - Fossils from South Australia are offering a surprising clue about the deep history of animal behavior. Spriggina floundersi, an ancient organism that lived about 550 million years ago, may represent the oldest known example of "right-handedness" in animals, suggesting a preference for turning right emerged long before hands, feet, or widespread complex...
EUREKA ALERT! - Scientists have uncovered what may be the earliest evidence of “right-handedness” in the animal kingdom, dating back more than half a billion years. The discovery comes from the fossil record of Spriggina floundersi, an organism from the Ediacaran Period that lived about 550 million years ago. New research published today in the...
SCIENTIFIC AMERICAN - Today a stretch of Canada’s remote Northwest Territories is covered in snow-covered peaks. But more than half a billion years ago this wilderness was an ancient seafloor home to the wrinkled pancakes, fleshy fronds and spiral-shaped critters that were among Earth’s earliest complex life-forms. Researchers recently unearthed a trove of fossils that...
YALE - The murky world at the bottom of the oceans is now a little clearer, thanks to a new study that tracks the evolution of marine sediment layers across hundreds of millions of years. It is a story of world-building on a grand, yet granular, scale, accomplished by a succession of marine animals that...
NATIONAL ACADEMY OF SCIENCES - The National Academy of Sciences announced today the election of 120 members and 30 international members in recognition of their distinguished and continuing achievements in original research. Those elected today bring the total number of active members to 2,662 and the total number of international members to 556. International members...
Mary Droser, Distinguished Professor of Geology in the UC Riverside Department of Earth and Planetary Sciences, likes to say that she is the luckiest and most privileged person she knows. To anyone considering her prodigious list of professional accomplishments, the eponymous head of the Droser Paleoecology Lab on campus certainly seems to have had a...
SCIENCE MAGAZINE - Some of Ian Hughes’s earliest memories are of playing in the dust and digging holes while his mom and her colleagues searched for fossils in South Australia. His mother, University of California, Riverside, paleoecologist Mary Droser, was searching for fossilized remnants of animals from the Ediacaran era, stretching from approximately 635 million...
INTERESTING ENGINEERING - Over 500 million years ago, the ancestors of a diverse group of animals known as Ecdysozoans existed. This group includes various species of insects, arachnids, and nematode worms. For a long time, the group’s early history was a blank page until now. A team of researchers has identified the earliest known ecdysozoan...
LIVE SCIENCE - The earliest known animal to show evidence of an asymmetrical body lived over half a billion years ago in what is now the Australian outback, a new study reports. The 555 million-year-old creature, dubbed Quaestio simpsonorum in a study published Sept. 3 in the journal Evolution and Development, was able to move...
NATIONAL GEOGRAPHIC - In the mid-20th century, geologist Reg Sprigg made a stunning discovery in South Australia’s Flinders Ranges. Under the searing outback sun, he unearthed delicate impressions made by animals that lived some 550 million years ago—the missing piece in our understanding of evolution that had long eluded naturalist Charles Darwin. Called the Ediacaran...
