Misunderstood Worm-Like Fossil Finds Its Place In The Tree Of Life

University of Cambridge One of the most bizarre-looking fossils ever found - a worm-like creature with legs, spikes and a head difficult to distinguish from its tail – has found its place in the evolutionary Tree of Life, definitively linking...

Researchers Find Rare Fossilized Embryos More Than 500 Million Years Old
2014-04-11 13:06:23

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...

Brett Smith for redOrbit.com - Your Universe Online Several large marine animals have evolved from fearsome predators to become gentle giants that use filtering appendages to ingest food, and new research from a team of European researchers has revealed a similar evolution in a group of predators that roamed the oceans 520 million years ago during the Early Cambrian. According to the team’s report in the journal Nature, an early arthropod called Tamisiocaris borealis used large curly...

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...

Signs Of Ancient Bacterial Ecosystems Found In Australia

April Flowers for redOrbit.com - Your Universe Online Scientists trying to reconstruct the rise of life during the period of Earth's history when it first evolved find the task daunting because the planet's oldest sedimentary rocks are not only rare, but nearly always altered by hydrothermal and tectonic activity. A new study, published in the journal Astrobiology, reveals the well-preserved remnants of a complex ecosystem in a nearly 3.5 billion-year-old sedimentary rock sequence in...

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...

[ 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...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
