Scientists at UCSB discover 600 million-year-old origins of vision
By studying the hydra, a member of an ancient group of sea creatures that is still flourishing, scientists at UC Santa Barbara have made a discovery in understanding the origins of human vision. The finding is published in this week's issue of the Proceedings of the Royal Society B, a British journal of biology. view more (2010-03-12)

Students' perceptions of Earth's age influence acceptance of human evolution, says U of Minn. study
High school and college students who understand the geological age of the Earth (4.5 billion years) are much more likely to understand and accept human evolution, according to a University of Minnesota study published in the March issue of the journal Evolution. view more (2010-03-11)
Strategic research program needed to determine whether, how past climate influenced human evolution
Understanding how past climate may have influenced human evolution could be dramatically enhanced by an international cross-disciplinary research program to improve the sparse human fossil and incomplete climate records and examine the link between the two, says a new report from the National Research Council. view more (2010-03-04)
Recently analyzed fossil was not human ancestor as claimed, anthropologists say
A fossil that was celebrated last year as a possible "missing link" between humans and early primates is actually a forebearer of modern-day lemurs and lorises. view more (2010-03-03)
Modern man found to be generally monogamous, moderately polygamous
Did women and men contribute equally to the lineage of contemporary populations? Did our ancestors, Homo sapiens, lean more toward polygamy or monogamy? view more (2010-03-03)
New dinosaur rears its head; U-M researchers part of team announcing find
The remains of a new herbivorous sauropod dinosaur, discovered near the world-famous Carnegie Quarry in Dinosaur National Monument, may help explain the evolution of the largest land animals ever to walk the earth. view more (2010-03-02)
DNA sequencing unlocks relationships among flowering plants
The origins of flowering plants from peas to oak trees are now in clearer focus thanks to the efforts of University of Florida researchers. view more (2010-02-24)

Genome sequencing of 3 parasitoid wasp species
An international consortium of scientists, including Universitat Autònoma de Barcelona (UAB) researcher Deodoro Oliveira, have sequenced the genome of three species of parasitoid wasps of the genus Nasonia. view more (2010-02-18)
Morality research sheds light on the origins of religion
The details surrounding the emergence and evolution of religion have not been clearly established and remain a source of much debate among scholars. view more (2010-02-09)
Brown biologist solves mystery of tropical grasses' origin
Around 30 to 40 million years ago, grasses on Earth underwent an epic evolutionary upheaval. An assemblage capitalized on falling levels of atmospheric carbon dioxide by engineering an internal mechanism to concentrate the dwindling CO2 supply that, like a fuel-injection system in a car, could more efficiently convert sunlight and nutrients into... view more...

Yes, ecology shapes evolution, but guppies show reverse also true
In the natural stream communities of Trinidad, guppy populations live close together, but evolve differently. Upstream, fewer predators mean more guppies but less food for each; they grow slowly and larger, reproduce later and less, and die older. view more (2010-02-05)
Carbonate veins reveal chemistry of ancient seawater
The chemical composition of our oceans is not constant but has varied significantly over geological time. In a study published this week in Science, researchers describe a novel method for reconstructing past ocean chemistry using calcium carbonate veins that precipitate from seawater-derived fluids in rocks beneath the seafloor. view more (2010-02-05)
The Sur, Baleares and Segura basins are the driest in Spain
There is some discrepancy among the scientific community as to the situation of reservoirs in Spain, one of the countries with the greatest water stress in Europe. For this purpose, a team of researchers has surveyed experts and has determined which basins in Spain have the most water problems. view more (2010-01-28)
Why humans outlive apes
The same evolutionary genetic advantages that have helped increase human lifespans also make us uniquely susceptible to diseases of aging such as cancer, heart disease and dementia. view more (2010-01-26)
Medical students may soon be tested on evolution

Penn biologists explain how organisms can tolerate mutations, yet adapt to environmental change
Biologists at the University of Pennsylvania studying the processes of evolution appear to have resolved a longstanding conundrum: How can organisms be robust against the effects of mutations yet simultaneously adaptable when the environment changes? view more (2010-01-21)
Study suggests theory for insect colonies as 'superorganisms'
New A team of researchers including scientists from the University of Florida has shown insect colonies follow some of the same biological "rules" as individuals, a finding that suggests insect societies operate like a single "superorganism" in terms of their physiology and life cycle. view more (2010-01-19)
