No Single Factor Behind Cambrian Explosion Of Animal Life
2013-09-20 07:58:01

April Flowers for redOrbit.com - Your Universe Online A new study from the UK reveals that the explosion of animal life on Earth that occurred around 520 million years ago was the result of a combination of interlinked factors, rather than a single underlying cause. Over the past few decades, dozens of individual theories have been put forth for the rapid diversification of animal species in the early Cambrian period. The new study, published in Science, suggests a more holistic...

Evolution Big Bang Fits Darwin Theory

[ Watch the Video: Big Bang Evolution Consistent With Darwin's Theory ] Brett Smith for redOrbit.com - Your Universe Online While most people consider Charles Darwin the father of evolutionary theory, even the great English naturalist himself questioned aspects of his theory based on certain elements of the fossil record. A new study from a team of English and Australian researchers explores one major flaw in Darwin’s theory backed by fossil evidence – the so-called ‘big...

Fossils Show Anatomy Of Ancient Fuxianhuiid Arthropod
2013-02-28 09:06:34

April Flowers for redOrbit.com - Your Universe Online An international group of scientists led by researchers at the University of Cambridge has made an extraordinary find in South China. For the first time, scientists are able to see through the head of the "fuxianhuiid" arthropod, revealing one of the earliest evolutionary examples of limbs used for feeding along with the oldest nervous system to stretch beyond the head in fossil record. Prior to this find, heads covered by a...

Ediacaran Fossils A 'First-class Scientific Mystery'
2012-12-13 08:50:07

redOrbit Staff & Wire Reports - Your Universe Online Mysterious multicellular fossils believed to be ancient sea creatures may actually be some of the earliest land-dwelling organisms, according to a paper published online on Wednesday in the journal Nature. The controversial hypothesis has been fiercely criticized, with some paleontologists flatly rejecting the idea, but if true, the finding would push back life's transition from sea to land by as much as 100 million years or more....

Cambrian Explosion Trigger Found In Grand Canyon
2012-04-20 04:50:27

Millions of years ago, the creatures who would become the ancestors of all life, animals and humans alike, were simple, sometimes composed of individual cells. Evolution had been slow, with very little diversification. Then, as the waters began to shift and separate exposing new areas of land to air and daylight, this slow evolution began to explode into activity. Referred to as the Cambrian Explosion, this diversification is estimated to have taken several million years itself, breeding many...

Image 1 - Paleontologists Discover Oldest Organism With A Skeleton
2012-03-10 05:50:09

Paleontologists have discovered the oldest organism with a skeleton in Australia. The creature is called Coronacollina acula and is estimated to be between 550 and 560 million years old. Paleontologists estimate this animal is from the Ediacaran Period, before the diversification of organisms in the Cambrian Period. The study results appeared online February 14 in Geology. This important find could be the key to unlocking several questions about early life, evolution, and extinction....

The Burgess Shale of British Columbia is arguably the most important fossil deposit in the world, providing an astounding record of the Cambrian "Explosion," the rapid flowering of complex life from single-celled ancestors. While most of the fossil record is comprised of shells, teeth and bones, the Burgess Shale preserves the softer bits–the eyes, guts, gills and other delicate structures–of animals belonging to Earth's earliest complex ecosystems a half a billion years ago. The...

Researchers Discover Ancient Tulip-like Creature In The Canadian Rockies
2012-01-20 07:49:18

A strange tulip-shaped creature discovered in half-a-billion-year-old rocks had a feeding system unlike any other animal, researchers reported this week. Officially named Siphusauctum gregarium, the fossils, unearthed from the Middle Cambrian Burgess Shale in the Canadian Rockies, reveal a peculiar creature roughly 7-8 inches long with a unique filter feeding system. The creature has a long stem with a bulbous cup-like structure -- similar to that of a tulip -- near the top that...

2011-11-09 08:57:09

Researchers from the University of Saskatchewan and Royal Ontario Museum (ROM) have followed fossilized footprints to a multi-legged predator that ruled the seas of the Cambrian period about half a billion years ago. "Short of finding an animal at the end of its trackway, it's really very rare to be able to identify the producer so confidently," said Nicholas Minter, lead author of the article on the study, which appears in the latest issue of the Proceedings of the Royal Society B. Minter...

Paleontologists have discovered 515-million-year-old fossils which show that ancient animals had excellent vision and could even see in the dark, reports the Telegraph. An international team of scientists led by the South Australian Museum and the University of Adelaide found the fossils, which look like "squashed eyes from a recently swatted fly," on Kangaroo Island in South Australia. Researchers said the eyes have more than 3,000 lenses, making them more powerful than any known eye fossil...
