Signs Of Ancient Bacterial Ecosystems Found In Australia
2013-11-13 05:44:54

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...

Max Planck Institute Arabidopsis plants that only reach half their normal height have a mutation in the biosynthesis of the plant growth factor gibberellin The normal height to which plants grow is a critical trait. In the wild Arabidopsis thaliana uses the same genetic changes in the biosynthesis of the growth factor gibberellin to cut its size in half as found in semi-dwarf varieties of rice and barley that have been bred by people. When expressing the same phenotype, various plant...

Bitter Taste Gene May Have Been Beneficial To Human Evolution
2013-11-12 13:31:37

Brett Smith for redOrbit.com - Your Universe Online It can be puzzling sometimes when someone else finds the taste of your favorite food to be disgusting, but research has shown we all perceive the taste of various compounds differently. A new study from researchers at the University of Pennsylvania has found a genetic mutation making certain people more sensitive to the taste of a bitter compound could have been beneficial for certain human populations in Africa, resulting in the...

Clay May Have Been Cradle Of Life
2013-11-08 11:08:34

[ Watch the Video: Life On Earth May Have Come From Clay ] Brett Smith for redOrbit.com - Your Universe Online Often viewed as an apparently infertile blend of various minerals, clay might have actually been the birthplace of life on Earth, biological engineers from Cornell University report in new research appearing in Thursday’s online edition of the journal Scientific Reports. The study authors set out to simulate ancient seawater in order to analyze the properties of clay under...

Two Mouths For One Worm
2013-11-07 11:58:54

Max-Planck-Gesellschaft A devious evolutionary path between genetics and environment Depending on the environment in which the worm grows, the larva of the roundworm Pristionchus pacificus develops into either a wide-mouthed predator or a narrow-mouthed bacteria eater. A team of researchers at the Max Planck Institute for Evolutionary Biology in Tübingen, Germany, headed by Ralf J. Sommer have now discovered a developmental biological switch that determines the worm's mouth form....

Evolving multicellular algae in the lab, researchers discover why it is better to go it alone during reproduction Scientists have puzzled for centuries over how and why multicellular organisms evolved the almost universal trait of using single cells, such as eggs and sperm, to reproduce. Now researchers led by University of Minnesota College of Biological Sciences postdoctoral fellow William Ratcliff and associate professor Michael Travisano have set a big piece of that puzzle into place...

Female guppies in Trinidad seek rare males as mates When it comes to choosing a mate, female guppies don't care about who is fairest. All that matters is who is rarest. Florida State University Professor Kimberly A. Hughes in the Department of Biological Science has a new study just published in the journal Nature that is the first to demonstrate a female preference for rare males using an experiment in a wild population, rather than a laboratory setting. This study of genetic...

Butterflies Offer Insights Into Evolution
2013-10-31 16:39:31

Michael Harper for redOrbit.com - Your Universe Online A new study from the University of Chicago finds it’s genetically easier to spin off into a new species than it may have once been thought, even if the two species remain close and interbreed with one another. After studying butterflies, the researchers found evolution can happen as the result of a process rather than a single event. In fact, in the case of butterflies, the beginning of a new species could begin with something as...

John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...

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...
