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 -
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 -
Evolution Is Written All Over Your Face
January 11, 2012 — Why are the faces of primates so dramatically different from one another? Biologists serving as "evolutionary detectives" studied the faces of 129 adult male primates from Central and South America, ... > 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 -
New Theory Emerges for Where Some Fish Became Four-Limbed Creatures
December 27, 2011 — A small fish crawling on stumpy limbs from a shrinking desert pond is an icon of can-do spirit, emblematic of a leading theory for the evolutionary transition between fish and amphibians. This ... > 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 -
