Bacteria reveal secret of adaptation at Evolution Canyon
Bacteria living on opposite sides of a canyon have evolved to cope with different temperatures by altering the make-up of their 'skin', or cell membranes. Scientists have found that bacteria change these complex and important structures to adapt to different temperatures by looking at the appearance of the bacteria as well as their genes. view more (2008-07-28)
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)
Evolutionary shifts in olfactory sensitivities in fruit flies
How do an animal's senses change as it evolves to occupy a new ecological niche? By comparing the olfactory system of the fruit fly Drosophila melanogaster, which feeds from multiple fruit types, with that of its sibling species D. sechellia, a specialist particularly drawn to a single fruit type. view more (2006-01-10)
Ancient protein offers clues to killer condition
More than 600 million years of evolution has taken two unlikely distant cousins - turkeys and scallops - down very different physical paths from a common ancestor. But University of Leeds researchers have found that a motor protein, myosin 2, remains structurally identical in both creatures. view more (2008-05-13)
Freshwater fish at the top of the food chain evolve more slowly
For avid fishermen and anglers, the largemouth bass is a favorite freshwater fish with an appetite for minnows. view more (2009-07-29)
Does life exist on other planets?
Recent research argues that an atmosphere rich in oxygen is the most likely source of energy for complex life to exist anywhere in the Universe, thereby limiting the number of places life may exist. view more (2005-06-20)
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)
Worker ants of the world, unite! You have nothing to lose but your fertility
The highly specialized worker castes in ants represent the pinnacle of social organization in the insect world. As in any society, however, ant colonies are filled with internal strife and conflict. So what binds them together? More than 150 years ago, Charles Darwin had an idea and now he's been proven right. view more (2008-11-20)
Museum specimens aid conservation effort in Madagascar
There is a new tool for those developing conservation strategies for threatened species and landscapes: museum specimens. Richard Pearson and Christopher Raxworthy of the American Museum of Natural History dusted off a number of collections from Madagascar and used the location information associated with each species to test different ideas... view more...

Stanford researchers show adaptation plays a significant role in human evolution
For years researchers have puzzled over whether adaptation plays a major role in human evolution or whether most changes are due to neutral, random selection of genes and traits. view more (2009-01-16)
Investigating the invisible life in our environment
Microorganisms make up more than a third of the Earth's biomass. They are found in water, on land and even in our bodies, recycling nutrients, influencing the planet's climate or causing diseases. view more (2007-02-02)
How Life Originated In Space
Life originated on the Earth more than 3.5 billion years ago. However, the scientists are still disputing over the possible sources of the life origin. The matter is that life on our planet evolved from the molecular level to the level of bacteria organisms within 0.5 - 1 billion years, this period being very short for such an important... view more...

Study reveals surprising details of the evolution of protein translation
A new study of transfer RNA, a molecule that delivers amino acids to the protein-building machinery of the cell, challenges long-held ideas about the evolutionary history of protein synthesis. view more (2008-08-13)
Origin of claws seen in 390-million-year-old fossil
A missing link in the evolution of the front claw of living scorpions and horseshoe crabs was identified with the discovery of a 390 million-year-old fossil by researchers at Yale and the University of Bonn, Germany. view more (2009-02-06)
Scientists force viruses to evolve as better delivery vehicles for gene therapy
Viruses and humans have evolved together over millions of years in a game of one-upmanship that, often as not, left humans sick or worse. view more (2006-02-08)
Kent State University Professor C. Owen Lovejoy helps unveil oldest hominid skeleton
Throw out all those posters and books that depict an ape evolving into a human being, says Kent State University Professor of Anthropology Dr. C. Owen Lovejoy. view more (2009-10-02)
EU-funded project to grow first artificial society
A EUR1.55 million project funded by the European Union's Sixth Framework Programme to grow the first society based on artificial, computer-based beings, much like characters in popular computer games such as SIMS, was officially launched on Wednesday during the AISB2005 convention at the University of Hertfordshire. view more (2005-04-14)
Evolutionary scrap-heap challenge: Antifreeze fish make sense out of junk DNA
Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA. view more (2006-04-04)
Time in a bottle: Scientists watch evolution unfold
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said. view more (2009-10-19)
Caltech astronomers describe the bar scene at the beginning of the universe
Bars abound in spiral galaxies today, but this was not always the case. A group of 16 astronomers, led by Kartik Sheth of NASA's Spitzer Science Center at the California Institute of Technology, has found that bars tripled in number over the past seven billion years, indicating that spiral galaxies evolve in shape. view more (2008-07-30)
