MicroRNAs have shaped the evolution of the majority of mammalian genes
RNA continues to shed its reputation as DNA's faithful sidekick. Now, researchers in the lab of Whitehead Institute Member David Bartel have found that a class of small RNAs called microRNAs influence the evolution of genes far more widely than previous research had indicated.   view more (2005-11-30)

Iowa State researcher studies gene families to explore diversity and evolution
Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve.   view more (2006-08-01)

Swedish-Chinese research team uncovers the history of the nose
Our ancestors had two nostrils, one front and one back, but no opening on the palate or in the throat. They could smell, but not breathe with their nose. How did our nose evolve? Per Ahlberg, Uppsala university, and Zhu Min, department of Vertebrate Paleontology in Beijing, China, has now found a fossil that explains the history of the nose.   view more (2004-11-03)

NASA Telescope Reveals Nearby Galaxy's Invisible Arms
A new image from NASA's Galaxy Evolution Explorer shows that a galaxy once thought to be rather plain and old is actually endowed with a gorgeous set of young spiral arms.   view more (2005-07-25)

Human culture subject to natural selection, Stanford study shows
The process of natural selection can act on human culture as well as on genes, a new study finds.   view more (2008-02-19)

Annual plants may cope with global warming better than long-living species
Countering Charles Darwin's view that evolution occurs gradually, UC Irvine scientists have discovered that plants with short life cycles can evolutionally adapt in just a few years to climate change.   view more (2007-01-09)

Evolution of animal personalities
Animals differ strikingly in character and temperament. Yet only recently has it become evident that personalities are a widespread phenomenon in the animal kingdom.   view more (2007-05-31)

Viral marker of human migration suspect
A benign virus previously used as a marker in tracing human migration may be unreliable.   view more (2006-10-25)

Bats add their voice to the FOXP2 story
When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language.   view more (2007-09-19)

UCI scientists reconstruct migration of avian flu virus
UC Irvine researchers have combined genetic and geographic data of the H5N1 avian flu virus to reconstruct its history over the past decade. They found that multiple strains of the virus originated in the Chinese province of Guangdong, and they identified many of the migration routes through which the strains spread regionally and internationally.   view more (2007-03-06)

Islands spark accelerated evolution
The notion of islands as natural test beds of evolution is nearly as old as the theory itself. The restricted scale, isolation, and sharp boundaries of islands create unique selective pressures, often to dramatic effect.   view more (2006-09-12)

Throwing light on the dark side of the Universe
Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe.   view more (2008-10-22)

Does natural selection drive the evolution of cancer?
The dynamics of evolution are fully in play within the environment of a tumor, just as they are in forests and meadows, oceans and streams. This is the view of researchers in an emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology.   view more (2006-11-20)

Discovery of a molecular mechanism underlying limb architecture
A genetic study performed by Dr. Marie Kmita, a researcher at the Institut de Recherches Cliniques de Montréal (IRCM), in collaboration with Drs Basile Tarchini and Denis Duboule of the University of Geneva in Switzerland, sheds light on the origins of the architecture of arms and legs.   view more (2006-10-26)

Ambient light influences the evolution of colour signals
In light-contrasted ecosystems, ambient light and background colours influence the evolution of animal coloration. Because maximal conspicuousness is achieved for signals which are rich in the colours of ambient light but poorly reflected by background, different signals will be cryptic or conspicuous at different heights in tropical rainforest.... view more...

New Study Has Important Implications for Influenza Surveillance
Researchers are reporting results of a study that substantially alters the existing understanding of how the influenza virus evolves and that could have important implications for monitoring changes to the virus and predicting which strains should be used for flu vaccine.   view more (2006-10-27)

Fungi can tell us about the origin of sex chromosomes
Fungi do not have sexes, just so-called mating types. A new study being published today in the prestigious journal PLoS shows that there are great similarities between the parts of DNA that determine the sex of plants and animals and the parts of DNA that determine mating types in certain fungi.   view more (2008-03-18)

HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at Earth Systems Processes, a multidisciplinary... view more... (2001-06-21)

Selection on genes underlying schizophrenia during human evolution
Several genes with strong associations to schizophrenia have evolved rapidly due to selection during human evolution.   view more (2007-09-05)

Adaptive functional evolution of leptin in cold-adaptive pika family
Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal.   view more (2008-01-23)
