New Fossil Organism Discovered By Paleontologists

By Iqbal Pittalwala, University of California - Riverside Likely related to our ancestors, 'Plexus ricei' was much like a tapeworm or modern flatworm, say UC Riverside researchers Scientists at the University of California, Riverside have discovered a fossil of a newly discovered organism from the "Ediacara Biota" — a group of organisms that occurred in the Ediacaran period of geologic time. Named Plexus ricei and resembling a curving tube, the organism resided on the Ediacaran...

Researchers Find Rare Fossilized Embryos More Than 500 Million Years Old

Jeff Sossamon, University of Missouri The Cambrian Period is a time when most phyla of marine invertebrates first appeared in the fossil record. Also dubbed the “Cambrian explosion,” fossilized records from this time provide glimpses into evolutionary biology when the world’s ecosystems rapidly changed and diversified. Most fossils show the organisms’ skeletal structure, which may or may not give researchers accurate pictures of these prehistoric organisms. Now, researchers at the...

Evolution Remained Stuck In Slime For A Billion Years

Science in Public Tasmanian researchers have revealed ancient conditions that almost ended life on Earth, using a new technique they developed to hunt for mineral deposits. The first life developed in the ancient oceans around 3.6 billion years ago, but then nothing much happened. Life remained as little more than a layer of slime for a billion years. Suddenly, 550 million years ago, evolution burst back into action – and here we are today. So what was the hold-up during those 'boring...

SEATTLE, Feb. 12, 2014 /PRNewswire-USNewswire/ -- A spectacular new discovery of Cambrian animal fossils has intensified a source of doubt that troubled Darwin about his theory, according to scientific researchers at Discovery Institute. About 26 miles from the famous Walcott quarry, a new exposure of Burgess Shale fossils has come to light. Called the Marble Canyon quarry, this fossil assemblage, reported in Scientific American, Nature Communications, and elsewhere, appears to be...

Bigger Really Was Better For Early Prehistoric Life

[ Watch the Video: The Evolution of the World’s Oldest Fossil Communities ] University of Toronto A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals. Laflamme, an assistant professor with the Department of Chemical and Physical Sciences, and his colleagues at the Massachusetts Institute of Technology Node of NASA's Astrobiology Institute suggest that height...

Oxygen Levels Prior To The Cambrian Explosion May Have Been Enough For Life
2013-10-19 05:00:29

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has discovered that the Earth’s oxygen content 2.1 billion years ago was the same as it was during the so-called Cambrian explosion that occurred approximately 542 years ago and resulted in the appearance of most major animal phyla. Given the fact that oxygen and the development of advanced life are inextricably linked, this led the study authors to ponder the sudden emergence of living...

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...

In DARWIN'S DOUBT, Meyer tackles the most controversial aspect of Darwin´s theory of evolution–the rapid appearance of animal life 530 million years ago–and expands the scientific argument for Intelligent Design. San Francisco, CA (PRWEB) June 17, 2013 “When Charles Darwin finished his famous book, he thought that he had explained every clue, but one.” So begins DARWIN´S DOUBT: The Explosive Origin of Animal Life and the Case for Intelligent Design...
