Slippery stretching explains ocean floor formation
For the first time, scientists have found regions of the earth's crust which are stretching apart to form new sea floor. view more (2006-07-31)
Evolution in action? African fish could be providing rare example of forming two separate species, Cornell scientists speculate
Avoiding quicksand along the banks of the Ivindo River in Gabon, Cornell neurobiologists armed with oscilloscopes search for shapes and patterns of electricity created by fish in the water. view more (2006-06-02)
Human-chimp difference may be bigger
Approximately 6 percent of human and chimp genes are unique to those species, report scientists from Indiana University Bloomington and three other institutions. view more (2006-12-20)
How a zebra lost its stripes: Rapid evolution of the quagga
DNA from museum samples of extinct animals is providing unexpected information on the extent and effect of the Ice Age as well as the path of species evolution, according to a report by scientists from Yale University, the Smithsonian Institute and the Max Planck Institute for Evolutionary Anthropology. view more (2005-09-27)
St. Jude conducts first large-scale bird flu genome study
Unique resources at St. Jude Children's Research Hospital let researchers generate a "gold mine" of data to track evolution of bird flu virus genes and understand how they cooperate to cause disease. view more (2006-01-27)
The difference between fish and humans: scientists answer century-old developmental question
Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century. view more (2007-10-11)
Origins of nervous system found in genes of sea sponge
Scientists at the University of California, Santa Barbara have discovered significant clues to the evolutionary origins of the nervous system by studying the genome of a sea sponge, a member of a group considered to be among the most ancient of all animals. view more (2007-06-06)
2 explosive evolutionary events shaped early history of multicellular life
Scientists have known for some time that most major groups of complex animals appeared in the fossils record during the Cambrian Explosion, a seemingly rapid evolutionary event that occurred 542 million years ago. view more (2008-01-04)
Conflict over rearing young shapes breeding systems
An article in the October 2006 issue of BioScience, the monthly journal of the American Institute of Biological Sciences (AIBS), describes evidence that conflict between male and female shorebirds over which member of a breeding pair will raise their young has had a profound influence on the evolution of breeding systems in these birds. view more (2006-10-03)
Oldest juvenile skeleton discovered will help piece together human development
Discovery of a nearly intact 3.3 million year-old juvenile skeleton is filling an important gap in understanding the evolution of a species thought to be among the earliest direct ancestors to humans. view more (2006-09-21)
Stanford evolution research cited by Science as a 2005 breakthrough
When the editors at Science looked back over the research reported in 2005, they decided that several high-impact discoveries made evolution stand out as the Breakthrough of the Year. view more (2005-12-23)
Life Cycle of Operons Yields New Look at Bacterial Genetics
In a breakthrough that will immediately benefit biologists who study bacteria, and could in the future have bearing on the advancement of synthetic biology, a team of researchers has determined the life cycle of operons, small groups of genes with related functions that are co-transcribed in a single strand of messenger RNA. view more (2006-07-06)
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)
Paleontologists discover new mammal from Mesozoic Era
An international team of American and Chinese paleontologists has discovered a new species of mammal that lived 125 million years ago during the Mesozoic Era, in what is now the Hebei Province in China. view more (2007-03-15)
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)
How did bilaterally symmetric flowers evolve from radially symmetric ones?
The researchers found that plants bearing bilaterally symmetrical flowers were more visited by pollinators and had higher fitness, measured by both the number of seeds produced per plant and the number of seeds surviving to the juvenile stage, than plants with radially symmetric flowers. view more (2006-10-03)
Gaining Ground in the Race Against Antibiotic Resistance
Antibiotic resistance has put humans in an escalating 'arms race' with infectious bacteria, as scientists try to develop new antibiotics faster than the bacteria can evolve new resistance strategies. view more (2005-09-20)
Salmonella survives better in stomach due to altered DNA
Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food. This type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics. view more (2007-01-31)
Selection of the fittest
A new study shows that schools and many education programmes are failing to provide students with a basic understanding of evolution. It is famously difficult to explain evolutionary principles without resorting to anthropomorphic or figurative language. Evolution 'selects' the fittest individuals; species 'adapt' to change. Both of these phrases... view more... (2002-03-18)
Neuron Cell Stickiness May Hold Key to Evolution of the Human Brain
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and Joint Genome Institute... view more...
