The first gene-encoded amphibian toxin isolated
Researchers in China have discovered the first protein-based toxin in an amphibian -a 60 amino acid neurotoxin found in the skin of a Chinese tree frog. This finding may help shed more light into both the evolution of amphibians and the evolution of poison. view more (2009-08-18)
Early fire use ignites discussion about the evolution of human brainpower
New evidence that early modern humans used fire in southern Africa in a controlled way to increase the quality and efficiency of stone tools is changing how researchers understand the evolution of human behavior, and in particular, the evolution of human brain power. view more (2009-08-14)
Biologists ID molecular basis of high-altitude adaptation in mice
Biologists have long known how adaptive evolution works. New mutations arise within a population and those that confer some benefits to the organism increase in frequency and eventually become fixed in the population. view more (2009-08-11)
Beautiful plumage: Feather color and sex start the species revolution
Faculty of 1000, the leading scientific evaluation service, has highlighted research providing evidence for the evolution of a new species. view more (2009-08-06)
Looking at language
The study of the neural basis of language has largely focused on regions in the cortex - the outer brain layers thought by many researchers to have expanded during human evolution. view more (2009-08-05)
Study finds human population expanded during late Stone Age
Genetic evidence is revealing that human populations began to expand in size in Africa during the Late Stone Age approximately 40,000 years ago. view more (2009-07-29)
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)
Resistance to antibiotics: When 1+1 is not 2
The evolution of multiple antibiotic resistances is a global and difficult problem to eradicate. view more (2009-07-24)
AIDS discovered in wild chimpanzees
Although the AIDS virus (HIV-1) entered the human population through chimpanzees, scientists have long believed that chimpanzees don't develop AIDS. view more (2009-07-23)
Ben-Gurion U. researchers reveal connection between cancer and human evolution
Researchers at Ben-Gurion University of the Negev (BGU) have discovered that gene mutations that once helped humans survive may increase the possibility for diseases, including cancer. view more (2009-07-06)
Study of flower color shows evolution in action
Scientists at UC Santa Barbara have zeroed in on the genes responsible for changing flower color, an area of research that began with Gregor Mendel's studies of the garden pea in the 1850's. view more (2009-06-30)
Competition May Be Reason For Bigger Brain
For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition. view more (2009-06-23)
Beaked, bird-like dinosaur tells story of finger evolution
Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs. view more (2009-06-18)
Evolution can occur in less than 10 years
How fast can evolution take place? In just a few years, according to a new study on guppies led by UC Riverside's Swanne Gordon, a graduate student in biology. view more (2009-06-11)
MU Study Finds Connection Between Evolution, Classroom Learning
Over thousands of years, humans have evolved to naturally understand things like facial expressions and social interactions. view more (2009-06-09)
Saved by junk DNA
VIB researchers linked to K.U.Leuven and Harvard University show that stretches of DNA previously believed to be useless 'junk' DNA play a vital role in the evolution of our genome. view more (2009-05-29)
Research suggests we may be genetically programmed to care about the long-term future
Humans may be programmed by evolution to care about the future of the environment, suggests research published today. view more (2009-05-28)

Thank parasites for making some of our immune proteins into the inflammatory defenders they are today. view more (2009-05-26)
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)
The neurobiology of musicality related to the intrinsic attachment behavior?
In the study of University of Helsinki and Sibelius Academy, Helsinki, the neurobiological basis of music in human evolution and communication was evaluated using candidate genes associated in the earlier studies with social bonding and cognitive functions. view more (2009-05-26)
