Pitt professor contends biological underpinnings
Jeffrey H. Schwartz, University of Pittsburgh professor of anthropology in the School of Arts and Sciences, is working to debunk a major tenet of Darwinian evolution. view more (2007-02-12)
Scientists Find a Fingerprint of Evolution Across the Human Genome
The Human Genome Project revealed that only a small fraction of the 3 billion "letter" DNA code actually instructs cells to manufacture proteins, the workhorses of most life processes. This has raised the question of what the remaining part of the human genome does. How much of the rest performs other biological functions, and how much... view more... (2008-04-09)
Birds learn to fly with a little help from their ancestors
It is widely known that birds learn to fly through practice, gradually refining their innate ability into a finely tuned skill. view more (2007-08-15)
In spiders, size matters: Small males are more often meals
Female spiders are voracious predators and consume a wide range of prey, which sometimes includes their mates. view more (2008-09-11)
Glasgow ecologist wins British Ecological Society award
Glasgow University ecologist Dr Hanna Kokko will be awarded the British Ecological Society~s Founders~ Prize at the BES Winter Meeting which will be held at the University of Birmingham on 3-5 January 2001. The prize is awarded every two years to an outstanding ecologist early in their career for making a significant contribution towards the... view more... (2000-12-15)
Hundreds of natural-selection studies could be wrong, study demonstrates
Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results. view more (2009-03-31)
Beyond a 'speed limit' on mutations, species risk extinction
Harvard University scientists have identified a virtual "speed limit" on the rate of molecular evolution in organisms, and the magic number appears to be 6 mutations per genome per generation -- a level beyond which species run the strong risk of extinction as their genomes lose stability. view more (2007-10-02)
Primordial fish had rudimentary fingers
Tetrapods, the first four-legged land animals, are regarded as the first organisms that had fingers and toes. Now researchers at Uppsala University can show that this is wrong. Using medical x-rays, they found rudiments of fingers in the fins in fossil Panderichthys, the "transitional animal," which indicates that rudimentary fingers... view more... (2008-09-22)
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)
Coelacanth fossil sheds light on fin-to-limb evolution
A 400 million-year-old fossil of a coelacanth fin, the first finding of its kind, fills a shrinking evolutionary gap between fins and limbs. view more (2007-08-01)
Genome archaeology illuminates the genetic engineering debate
Genome Research's cover story for Oct. 2 tells a tale of "genome archaeology" by genetic researchers who dug deeply into the long history of maize and rice. view more (2006-10-04)
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)
Comparative genomics reveals molecular evolution of Q fever pathogen
Scientists from the National Institute of Allergy and Infectious Diseases, Texas A&M Health Center, and the Virginia Bioinformatics Institute at Virginia Tech have uncovered genetic clues about why some strains of the pathogen Coxiella burnetii are more virulent than others. view more (2009-02-03)
Blame Our Evolutionary Risk of Cancer on Our Body Mass
A key enzyme that cuts short our cellular lifespan in an effort to thwart cancer has now been linked to body mass. view more (2006-12-06)
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)
Sticks and Stones: A New Study on Social and Physical Pain
We all know the famous saying: "Sticks and stones may break my bones, but words will never hurt me," but is this proverb actually true? view more (2008-08-28)
Low oxygen and molybdenum in ancient oceans delayed evolution of life by 2 billion years
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth by nearly two billion years, a study led by UC Riverside biogeochemists has found. view more (2008-03-27)
Smart and social?
Packs of hunting dogs, troops of baboons, herds of antelope: when people observe social animals, they are often struck by how intelligent they seem, and recent studies suggest that sociality has played a key role in the evolution of larger brain size among several orders of mammals. view more (2009-05-26)
Bacteria from sponges make new pharmaceuticals
Thousands of interesting new compounds have been discovered inside the bodies of marine sponges. view more (2007-09-04)
Earliest known fossil fish discovered in China
Professor Simon Conway Morris, of the Department of Earth Sciences, University of Cambridge, and Professor Degan Shu, of Northwest University, in Xi'an, China, have been analysing the fossils, along with eight other scientists from China. view more (1999-11-02)
