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)
Darwin's greatest challenge tackled: the mystery of eye evolution
When Darwin's skeptics attack his theory of evolution, they often focus on the eye. Darwin himself confessed that it was "absurd" to propose that the human eye evolved through spontaneous mutation and natural selection. Scientists at the European Molecular Biology Laboratory (EMBL) have now tackled Darwin's major challenge in an... view more... (2004-10-26)
Why do rodents' teeth stay sharp? What is the difference between the mouse and the kangaroo?
Answers to these two questions are given by two recent studies on tooth development and evolution. Scientists at the University of Helsinki have identified the gene responsible for tooth enamel formation, which also explains the sharp incisors of rodents. The second study adds to our knowledge on evolution: the differences between teeth in various... view more... (2004-11-10)
There's a speed limit to the pace of evolution, Penn biologists say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." view more (2009-11-03)
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)
How plants learned to respond to changing environments
A team of John Innes centre scientists lead by Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment. view more (2007-07-13)
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)
Man's best friend lends insight into human evolution
Flexibly drawing inferences about the intentions of other individuals in order to cooperate in complex tasks is a basic part of everyday life that we humans take for granted. view more (2007-03-02)
Astronomers find the most distant star clusters hidden behind a nearby cluster
Astronomers have discovered the most distant population of star clusters ever seen, hidden behind one of the nearest such clusters to Earth. view more (2007-01-11)
Lack of potential mates has lead to "sloppy" gene control and risk of disease for humans
Our evolutionary ancestors' lack of choice in the mating game has left modern humans exposed to disease, according to new research published in the journal PLOS Biology tomorrow (Tuesday 25 January 2005). view more (2005-01-24)
Annuals converted into perennials
Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create permanent structures. view more (2008-11-10)
A Glimpse of the Very Early Universal Web
The VLT Maps Extremely Distant Galaxies New, trailblazing observations with the ESO Very Large Telescope (VLT) at Paranal lend strong support to current computer models of the early universe: It is "spongy", with galaxies forming along filaments, like droplets along the strands of a spiders web. A group of astronomers at ESO and in Denmark... view more... (2001-05-18)
Smithsonian's National Museum of Natural History reveals ants as fungus farmers
It turns out ants, like humans, are true farmers. The difference is that ants are farming fungus. view more (2008-03-25)
Researchers sequence the basal eukaryote Tetrahymena thermophila
In an effort to improve our understanding of eukaryotic evolution, a team of over 50 researchers led by Jonathan Eisen sequenced the macronuclear genome of the single-celled ciliate Tetrahymena themophila. view more (2006-08-29)
Accelerated evolution converts RNA enzyme to DNA enzyme in vitro
This 'evolutionary conversion' provides a modern-day snapshot of how life as we understand it may have first evolved out of the earliest primordial mix of RNA-like molecules-sometimes referred to as the "pre-RNA world"-into a more complex form of RNA-based life (or the "RNA world") and eventually to cellular life based on DNA... view more...

Butterfly restrains Darwin
In experiments with butterflies, evolutionary biologists from Leiden University have demonstrated that natural selection is not always the only factor which determines the appearance of an organism. Constraints also appear to play a role at times in determining the progress and outcome of the evolutionary process. This research from Leiden... view more... (2002-10-24)
Molecular sleuths track evolution through the ribosome
A new study of the ribosome, the cell's protein-building machinery, sheds light on the oldest branches of the evolutionary tree of life and suggests that differences in ribosomal structure between the three main branches of that tree are "molecular fossils" of the early evolution of protein synthesis. view more (2008-08-19)
First 'rule' of evolution suggests that life is destined to become more complex
In a study published in the Proceedings of the National Academy of Sciences researchers have found evidence which suggests that evolution drives animals to become increasingly more complex. view more (2008-03-18)
Unlocking The Secrets Of Evolution
Exactly fifty years ago, Watson and Crick revealed the structure of DNA, unleashing a scientific revolution. On the anniversary of that momentous discovery, the world's leading science journal, Nature, will publish new and groundbreaking genetic research by Bangor University scientist, Dr. Isabelle Colson. Isabelle is an expert in evolutionary... view more... (2003-03-06)
Third primate genome, the rhesus macaque, helps illuminate what makes us human
Researchers have sequenced the genome of the relatively ancient rhesus macaque (Macaca mulatta), providing perspective into how humans are genetically different from our primate relatives. view more (2007-04-13)
