Human culture subject to natural selection, Stanford study shows
The process of natural selection can act on human culture as well as on genes, a new study finds. view more (2008-02-19)
Singing in the rainforest: Public vs. private signaling by a tropical rainforest bird
According to the Chinese proverb, a bird sings because it has a song, not because it has an answer. A team of French and Brazilian researchers, however, may have the answer as to how the song of Brazilian white-browed warbler has become so well-adapted to the acoustic properties of the rainforest environment. view more (2008-02-13)
Dartmouth researchers find the root of the evolutionary emergence of vertebrates
Dartmouth College researchers and colleagues from the University of Bristol in the U.K. have traced the beginnings of complex life, i.e. vertebrates, to microRNA. The researchers argue that the evolution of microRNAs, which regulate gene expression, are behind the origin of early vertebrates. view more (2008-02-12)
Evolutionary 'battle scars' identify enhanced anti-viral activity
Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center. view more (2008-01-25)
New insights into vaccination for HIV
A group of Australian researchers at the Universities of Melbourne and New South Wales have developed new tools and paradigms to understand immune evasion from HIV. view more (2008-01-25)

Adaptive functional evolution of leptin in cold-adaptive pika family
Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal. view more (2008-01-23)
Study discovers secret of Scottish sheep evolution
Researchers from the University of Sheffield, as part of an international team, have discovered the secret of why dark sheep on a remote Scottish Island are mysteriously declining, seemingly contradicting Darwin's evolutionary theory. view more (2008-01-18)
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)
Scientists find missing evolutionary link using tiny fungus crystal
The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex. view more (2008-01-03)
Evolution education is a 'must' says coalition of scientific and teaching organizations
A coalition of 17 organizations, including the National Academy of Sciences, the American Institute of Physics, and the National Science Teachers Association, is calling on the scientific community to become more involved in the promotion of science education, including evolution. view more (2008-01-02)
A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases. view more (2007-12-21)
Rebuilding the evolutionary history of HIV-1 unravels a complex loop
An essential component of the human immunodeficiency virus (HIV-1) molecular machinery responsible for infecting cells consists of functionally-specialized layers, according to a study by investigators at the University of California San Diego (UCSD) Antiviral Research Center (AVRC), published November 23 in PLoS Computational Biology. view more (2007-11-26)
Genome comparison of 12 fruit fly species
Researchers from the UAB Genomics, Bioinformatics and Evolution Group participated in an international research that has resulted in the completion of the genomes of ten new fruit fly species. The study also includes new data on the evolution of the twelve currently known species during the past sixty million years. view more (2007-11-16)
Parasites might spur evolution of strange amphibian breeding habits
Parasites can decimate amphibian populations, but one University of Georgia researcher believes they might also play a role in spurring the evolution of new and sometimes bizarre breeding strategies. view more (2007-11-15)
Researchers successfully simulate photosynthesis and design a better leaf
University of Illinois researchers have built a better plant, one that produces more leaves and fruit without needing extra fertilizer. The researchers accomplished the feat using a computer model that mimics the process of evolution. Theirs is the first model to simulate every step of the photosynthetic process. view more (2007-11-12)
Scientists complete DNA sequencing and analysis of multiple fruit fly genomes
In one of the first large-scale comparisons of multiple animal genomes, scientists at the Broad Institute of MIT and Harvard, the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT, and many collaborating institutions, have analyzed the genomes of twelve species of the fruit fly Drosophila to reveal insights on the evolution of... view more...

When animals evolve on islands, size doesn't matter
A theory explaining the evolution of giant rodents, miniature elephants, and even miniature humans on islands has been called into questions by new research published today in Proceedings of the Royal Society B: Biological Sciences. view more (2007-11-07)
Burrowing mammals dig for a living, but how do they do that?
Next time you see a mole digging in tree-root-filled soil in search of supper, take a moment to ponder the mammal's humerus bones. view more (2007-10-29)
St. Bernard study casts doubt on creationism
The St Bernard dog - named after the 11th century priest Bernard of Menthon - may have ironically challenged the theory of creationism, say scientists. view more (2007-10-24)
