Biologists Replicate Key Evolutionary Step
January 17, 2012 — More than 500 million years ago, single-celled organisms on the Earth's surface began forming multicellular clusters that ultimately became plants and animals. Just how that happened is a question ... > full story -
Most Recent European Great Ape Discovered
January 13, 2012 — Based on a hominid molar, scientists from Germany, Bulgaria and France have documented that great apes survived in Europe in savannah-like landscapes until seven million years ... > full story -
Novel Chemical Route to Form Organic Molecules
January 13, 2012 — Scientists have discovered a novel chemical route to form polycyclic aromatic hydrocarbons -- complex organic molecules such as naphthalene carrying fused benzene rings -- in ultra-cold regions of ... > full story -
Breakthrough Model Reveals Evolution of Ancient Nervous Systems Through Seashell Colors
January 12, 2012 — Determining the evolution of pigmentation patterns on mollusk seashells -- which could aid in the understanding of ancient nervous systems -- has proved to be a challenging feat for researchers. Now, ... > full story -
New Insights Into an Ancient Mechanism of Mammalian Evolution
January 12, 2012 — A team of geneticists and computational biologists have reveal how an ancient mechanism is involved in gene control and continues to drive genome ... > full story -
Molecular 'Culprit' in Rise of Planetary Oxygen
January 10, 2012 — A turning point in the history of life occurred two to three billion years ago with the unprecedented appearance and dramatic rise of molecular oxygen. Now researchers report they have identified an ... > full story -
Simpler Times: Did an Earlier Genetic Molecule Predate DNA and RNA?
January 9, 2012 — Scientists have described the Darwinian evolution of functional TNA molecules from a large pool of random sequences. This is the first case where such methods have been applied to molecules other ... > full story -
Evolution of Complexity Recreated Using 'Molecular Time Travel'
January 8, 2012 — Scientists have now demonstrated how just a few small, high-probability mutations increased the complexity of a molecular machine more than 800 million years ago. By biochemically resurrecting ... > full story -
Genetic Study of Black Chickens Shed Light on Mechanisms Causing Rapid Evolution in Domestic Animals
December 22, 2011 — The genetic changes underlying the evolution of new species are still poorly understood. For instance, we know little about critical changes that have happened during human evolution. Genetic studies ... > full story -
Birds Caught in the Act of Becoming a New Species
December 8, 2011 — A study of South American songbirds has shown that these birds differ dramatically in color and song yet show very little genetic differences, indicating they are on the road to becoming a new ... > full story -
Ancient Meat-Loving Predators Survived for 35 Million Years
December 6, 2011 — A species of ancient predator with saw-like teeth, sleek bodies and a voracious appetite for meat survived a major extinction at a time when the distant relatives of mammals ruled the ... > full story -
Early Earth May Have Been Prone to Deep Freezes, Study Finds
December 5, 2011 — Researchers who have adapted a three-dimensional, general circulation model of Earth's climate to a time some 2.8 billion years ago when the sun was significantly fainter than present think the ... > full story
