A new tree of life allows a closer look at the origin of species
In 1870 the German scientist Ernst Haeckel mapped the evolutionary relationships of plants and animals in the first 'tree of life'. view more (2006-03-03)
Biodiversity promotes evolutionary change
Evolutionary biologists at the University of East Anglia have discovered a new link between biodiversity and the evolution of new species. view more (2005-04-18)
Evolution: fish select for the survival of teh fittest
An important breakthrough has been made in determining the forces responsible for the evolution of populations in nature. By studying wild populations of grayling (a close relative of salmon), Mikko Koskinen and Craig Primmer at the University of Helsinki and Thrond Haugen at the University of Oslo found that natural selection, a force suggested... view more...

LSU scientists develop new theory about human genome evolution
A group of LSU researchers, led by biological sciences Professor Mark Batzer, have unraveled the details of a 25-million-year-old evolutionary process in the human genome. Their study focused on the origin and spread of transposable elements in the genome, many of which are known to be related to certain genetic disorders, such as hemophilia. view more (2005-07-01)
Mouse to man: The story of chromosomes
The complete sequencing of human chromosome 17 and mouse chromosome 11 offers unique insights into the evolution of the genome of higher mammals. view more (2006-04-20)
Intelligently Designed Molecular Evolution
Evolutionary paths to new therapeutic drugs, as well as a wide assortment of other enzyme products, have been created through, of all things, intelligent design. A team of researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a technique in which the evolution of an... view more...

Getting an evolutionary handle on life after reproduction
Since many animals live beyond their fertile years, biologists have searched for evolutionary clues to this extended lifespan. view more (2005-12-27)
Is there really a 'mommy' gene in women?
Basic principles of biology rather than women's newfound economic independence can explain why fewer of them are getting married and having children, and why the trend may only be temporary, says a Queen's researcher. view more (2007-09-24)
K-State researchers study gene regulation in insects
Susan Brown, an associate professor of biology at Kansas State University, is interested in how evolution generates so much diversity in insects shapes and forms. view more (2006-04-28)
Finding an answer to Darwin's Dilemma
The sudden appearance of large animal fossils more than 500 million years ago - a problem that perplexed even Charles Darwin and is commonly known as "Darwin's Dilemma" - may be due to a huge increase of oxygen in the world's oceans, says Queen's paleontologist Guy Narbonne, an expert in the early evolution of animals and their... view more...

UCSD Study Shows Junk DNA Has Evolutionary Importance
Genetic material derisively called "junk" DNA because it does not contain the instructions for protein-coding genes and appears to have little or no function is actually critically important to an organism's evolutionary survival, according to a study conducted by a biologist at UCSD. view more (2005-10-20)
Scientists' cell discovery unearths evolutionary clues
The full family tree of the species known as social amoebas has been plotted for the first time - a breakthrough which will provide important clues to the evolution of life on earth. view more (2006-10-30)
Animals can change genes quickly to keep up with viral ingenuity
Viruses are famous for evolving quickly, but the organisms they infect can't be expected to sit idly by. view more (2006-03-21)
Chimpanzee study reveals genome variation hotspots
Researchers believe that dynamic regions of the human genome - "hotspots" in terms of duplications and deletions - are potentially involved in the rapid evolution of morphological and behavioral characteristics that are genetically determined. view more (2006-05-16)
University of Chicago study overturns conventional theory in evolution
New data suggest that the accumulation of genetic changes is not solely determined by natural selection. A study by University of Chicago researchers contradicts conventional theory by showing that the percentage of mutations accepted in evolution is also strongly swayed by the speed at which new mutations arrive at a gene: the faster the speed of... view more...

Scientist's persistence sheds light on marine science riddle
When he started compiling an online database of seashells 15 years ago, Dr. Gary Rosenberg did not envision that his meticulous record-keeping would eventually shed light on a 40-year-old evolutionary debate. view more (2006-09-08)
Fruitfly study shows how evolution wings it
In the frantic world of fruitfly courtship, the difference between attracting a mate and going home alone may depend on having the right wing spots. view more (2006-04-20)
First RAVE data release offers clues to Milky Way evolution
An international team of astronomers released to the public the first data collected as part of the Radial Velocity Experiment, an ambitious spectroscopic survey aimed at measuring the speed, temperature, surface gravity and composition of up to a million stars passing near the sun. view more (2006-02-13)
Key brain regulatory gene shows evolution in humans
Researchers have discovered the first brain regulatory gene that shows clear evidence of evolution from lower primates to humans. view more (2005-12-13)
Controversial findings help explain evolution of life
Chemists at Oregon State University have pioneered a controversial theory about how supposedly-stable DNA bases can be pushed into a "dark state" in which they are highly vulnerable to damage from ultraviolet radiation - an idea that has challenged some of the most basic concepts of modern biochemistry. view more (2006-04-07)
