The study by researchers at University of Edinburgh in UK suggests that complex animals existed long before a period in the planet’s history, known as the Cambrian explosion, during which most major animal groups evolved.The China O ring Manufacturers first animals to have complex skeletons existed about 550 million years ago, millions of years earlier than previously thought, according to a new study. Until now, the oldest evidence of complex animals, which succeeded more primitive creatures that often resembled sponges or coral, came from the Cambrian Period, which began around 541 million years ago, researchers said. The team studied fossils of an extinct marine animal, known as Namacalathus hermanastes, which was widespread during the Ediacaran Period.

The finding suggests that bilaterians may have lived as early as 550 million years ago, during the late Ediacaran Period..Scientists studied fossils of tiny marine creatures unearthed in Namibia which may be related to many of today’s animal species. Genetic family tree data suggested that complex animals, known as bilaterians, evolved prior to the Cambrian Period.

"At first we were just interested in whether you can at all use wireless signals to detect what’s happening in occluded spaces, behind a wall, couch, something like that," Katabi said.

"Think of it just like cameras, except that it’s not a camera," said Fadel Adib, a researcher on the MIT team developing the device.The wireless signals used to track a person’s motions also can measure the individual’s breathing and heart rate — and potentially identify the person based on the shape of his or her skeleton, said researcher Zach Kabelac.Researchers say the technology will be able to help health care providers and families keep closer tabs on toddlers and the elderly, and it could be a new strategic tool for law enforcement and the military.
