Evolution Big Bang Fits Darwin Theory
2013-09-12 15:31:02

[ 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...

The Land Invasion Race: The Evolution Of Fins To Limbs
2013-07-07 19:51:23

Society for Experimental Biology Why did animals with limbs win the race to invade land over those with fins? A new study comparing the forces acting on fins of mudskipper fish and on the forelimbs of tiger salamanders can now be used to analyze early fossils that spanned the water-to-land transition in tetrapod evolution, and further understand their capability to move on land. Research conducted by Sandy Kawano and Richard Blob at Clemson University compared terrestrial locomotion in...

Ehux Algae Adapts With Variable Genome
2013-06-13 09:15:51

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has sequenced the genome of Emiliania huxleyi, a species of single-celled photosynthetic marine algae that they say is responsible for removing carbon dioxide from the air, supplying the oxygen we breath, and even forming the basis of marine food chains. The results of their work has just been published in the journal Nature and helps explain the tremendous adaptive potential and global...

3 billion-year-old Rocks Contain Microfossils Of Plankton
2013-06-06 21:18:25

Penn State Spindle-shaped inclusions in 3 billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to an international team of researchers. "It is surprising to have large, potentially complex fossils that far back," said Christopher H. House, professor of geosciences, Penn State, and lead author. However, the researchers not only showed that these inclusions in the rocks were biological in origin, but also...

Evolution Of Hips Simpler Than Suspected
2013-05-15 12:04:37

April Flowers for redOrbit.com - Your Universe Online The evolutionary path from the bone structure of the fish to the complex, weight-bearing hips of walking animals was a much simpler process than previously thought, according to a new study. About 395 million years ago, the first tetrapods, or four-legged animals, stepped onto land. This transition was accomplished using strong, weight-bearing hipbones and a connection through the spine via the ilium. These features were not present...

New Excavations Indicate Use Of Fertilizers During The Scandinavian Stone Age
2013-04-26 12:20:27

University of Gothenburg Researchers from the University of Gothenburg, Sweden, have spent many years studying the remains of a Stone Age community in Karleby outside the town of Falköping, Sweden. The researchers have for example tried to identify parts of the inhabitants' diet. Right now they are looking for evidence that fertilizers were used already during the Scandinavian Stone Age, and the results of their first analyses may be exactly what they are looking for. Using...

Genome Of The Coelacanth Sequenced
2013-04-18 05:26:08

April Flowers for redOrbit.com - Your Universe Online The genome of the coelacanth, a creature with an evolutionary history that is both enigmatic and illuminating, has been decoded by the Genome Center of the Broad Institute of MIT and Harvard, and analyzed by an international team of researchers. The findings of this study are published in the journal Nature. The coelacanth, a sea-cave dwelling, five-foot long fish with limb-like fins, was once thought to be extinct until a living...

New Genetic Study Of Tadpole Shrimps Casts Doubt On The Validity Of The Term 'Living Fossil'
2013-04-02 08:10:15

PeerJ The term 'living fossil' has a controversial history. For decades, scientists have argued about its usefulness as it appears to suggest that some organisms have stopped evolving. New research has now investigated the origin of tadpole shrimps, a group commonly regarded as 'living fossils' which includes the familiar Triops. The research reveals that living species of tadpole shrimp are much younger than the fossils they so much resemble, calling into question the term 'living...

Distant Relatives Of Gardeners’ Friend Discovered
2013-03-07 15:11:36

Simon Fraser University In a new article published in the Journal of Paleontology, two paleontologists, including one from Simon Fraser University, describe the most diverse group of fossilized green lacewing insects known. Green lacewings are familiar to gardeners, who value them in organic pest control, for their consumption of large numbers of aphids. The closest modern relatives to these insects are most diverse in southeastern Australia, the southwestern United States and...

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...

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

Paleozoology
2013-09-30 13:34:57

Paleozoology, also spelled Palaeozoology, is a branch of many other sciences including zoology and paleontology that focuses on recovering cellular matter from animal remains that are large enough to be seen without the help of a microscope, known as macrofossils. This study is primarily used in the context of archeology and geology and aids in recreating ancient ecosystems and prehistoric environments. Paleozoologists study the tissues of many types of animals including sharks, echinoderms,...

Bennett’s feather star, Oxycomanthus bennetti
2013-08-04 08:28:29

Bennett's feather star is a suspension feeder that grows to be about 1 foot with 31-120 arms extending upward from the body. The star catches the food, usually phytoplankton and zooplankton, with tubed feet located on the outside of the arms. Yellow, Brown, Green and Purple are the most common colors for the Bennett's feather star. The star will remain attached to the seabed by a stalk until it reaches maturity and then becomes free-living by breaking off from the stalk. The Bennett's...

Variable bushy feather star, Comaster Schlegelii
2013-05-18 06:46:30

The Variable bushy feather star is commonly found concealed on shallow water reefs in the western Pacific Ocean. The parts that will be most often seen are the fern-like arms. The arms start at the base with five rays then begin to divide from there. The arms are flexible due to the multiple calcium filled joints, also called ossicle; therefore if needed these arms could coil up and provide protection to the main body. Interestingly, if one arm should fall off, or perhaps pulled off, then two...

Noble feather star, Comaster nobilis
2013-05-18 06:36:19

The noble feather star (also known as the yellow feather star) reaches up to 15.75 inches in diameter with a cup-shaped body. There can be 35-40 arms extending out of the central part of the body. The arms are primarily yellow with the underside having a variation to include black, green, or white. The noble feather star feeds on food debris, phytoplankton and zooplankton. Phytoplankton and zooplankton are microscopic organisms that are present mainly in the layer of the oceans that is...
