Natural selection has strongly influenced recent human evolution, Cornell/Celera Genomics study finds
he most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species. view more (2005-10-24)
Video game Everquest 2 provides new way to study human behavior, says U of Minnesota researcher
Can researchers study the populations of online video games, like Everquest 2, just as they study traditional communities like Miami, Pittsburgh or Minneapolis? view more (2009-03-02)
Fossil discovery marks earliest record of limbloss in ancient lizard
A University of Alberta paleontologist has helped discover the existence of a 95 million-year-old snakelike marine animal, a finding that provides not only the earliest example of limbloss in lizards but the first example of limbloss in an aquatic lizard. view more (2007-03-23)
Why can't chimps speak?
If humans are genetically related to chimps, why did our brains develop the innate ability for language and speech while theirs did not? view more (2009-11-12)
Uncertain rainy days make birds turn to family, Cornell study finds
Rather than striking out to raise their family, members of some bird species cooperate to help raise their siblings, nephews, nieces, cousins -- or even unrelated young. Researchers have long noted which factors lead to these seemingly altruistic decisions, but now for the first time, Cornell researchers have linked a specific environmental factor... view more...

Swedish-Chinese research team uncovers the history of the nose
Our ancestors had two nostrils, one front and one back, but no opening on the palate or in the throat. They could smell, but not breathe with their nose. How did our nose evolve? Per Ahlberg, Uppsala university, and Zhu Min, department of Vertebrate Paleontology in Beijing, China, has now found a fossil that explains the history of the nose. view more (2004-11-03)
The evolutionary foundation of genomic imprinting in lower vertebrates
A Chinese scientist group working in College of Life Science, Zhejiang University, has shown that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island has a parental differentially methylated region (DMR). view more (2009-05-18)
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...

New dinosaur species possible in Northwestern Alberta
The discovery of a gruesome feeding frenzy that played out 73 million years ago in northwestern Alberta may also lead to the discovery of new dinosaur species in northwestern Alberta. view more (2009-05-13)
Yerkes researchers identify language feature unique to human brain
Researchers at the Yerkes National Primate Research Center, Emory University, have identified a language feature unique to the human brain that is shedding light on how human language evolved. The study marks the first use of diffusion tensor imaging (DTI), a non-invasive imaging technique, to compare human brain structures to those of... view more... (2008-03-24)
Spitzer nets thousands of galaxies in a giant cluster
In just a short amount of time, NASA's Spitzer Space Telescope has bagged more than a thousand previously unknown dwarf galaxies in a giant cluster of galaxies. view more (2007-05-29)
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)
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)
A gene divided reveals the details of natural selection
In a molecular tour de force, researchers at the University of Wisconsin-Madison have provided an exquisitely detailed picture of natural selection as it occurs at the genetic level. view more (2007-10-11)
Space And Security Policy In Europe
A study on "Space and Security Policy in Europe" was initiated by ESA in the framework of its General Studies Programme. It has been performed by a network of European experts in space and security under the coordination of IAI (Istituto Affari Internazionali, Italy). The research team included also: European Union Institute for... view more... (2003-12-11)
Migrating squid drove evolution of sonar in whales and dolphins, researchers argue
Behind the sailor's lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths" view more (2007-09-06)
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)
Most human-chimp differences due to gene regulation - not genes
The vast differences between humans and chimpanzees are due more to changes in gene regulation than differences in individual genes themselves, researchers from Yale, the University of Chicago, and the Hall Institute in Parkville, Victoria, Australia, argue in the 9 March 2006 issue of the journal Nature. view more (2006-03-09)
Charting HIV's rapidly changing journey in the body
HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells. view more (2008-12-12)
Sex: Why bother? Evolutionary mysteries probed at UH
What advantage did sex offer when it first appeared and why does sex persist in modern organisms, stopping them from becoming asexual again? view more (2006-03-02)
