A glimpse at the Earth's crust deep below the Atlantic
Long-term variations in volcanism help explain the birth, evolution and death of striking geological features called oceanic core complexes on the ocean floor, says geologist Dr Bram Murton of the National Oceanography Centre, Southampton. view more (2009-11-13)
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)
AIBS publishes Darwin articles open access
To celebrate the 150th anniversary this month of the publication of On the Origin of Species, the American Institute of Biological Sciences (AIBS) is publishing open access two peer-reviewed articles about Charles Darwin and his historic insights into evolution. view more (2009-11-09)
There's a speed limit to the pace of evolution, Penn biologists say
Researchers at the University of Pennsylvania have developed a theoretical model that informs the understanding of evolution and determines how quickly an organism will evolve using a catalogue of "evolutionary speed limits." view more (2009-11-03)
A solution to Darwin's 'mystery of the mysteries' emerges from the dark matter of the genome
Biological species are often defined on the basis of reproductive isolation. Ever since Darwin pointed out his difficulty in explaining why crosses between two species often yield sterile or inviable progeny (for instance, mules emerging from a cross between a horse and a donkey), biologists have struggled with this question. view more (2009-10-27)
The first men and women from the Canary Islands were Berbers
A team of Spanish and Portuguese researchers has carried out molecular genetic analysis of the Y chromosome (transmitted only by males) of the aboriginal population of the Canary Islands to determine their origin and the extent to which they have survived in the current population. view more (2009-10-22)
2-million-year-old evidence shows tool-making hominins inhabited grassland environments
In an article published in the open-access, peer-reviewed journal PLoS ONE on October 21, 2009, Dr Thomas Plummer of Queens College at the City University of New York, Dr Richard Potts of the Smithsonian Institution National Museum of Natural History and colleagues report the oldest archeological evidence of early human activities in a grassland... view more...

Are humans still evolving? Absolutely, says a new analysis of a long-term survey of human health
Although advances in medical care have improved standards of living over time, humans aren't entirely sheltered from the forces of natural selection, a new study shows. view more (2009-10-20)
Time in a bottle: Scientists watch evolution unfold
A 21-year Michigan State University experiment that distills the essence of evolution in laboratory flasks not only demonstrates natural selection at work, but could lead to biotechnology and medical research advances, researchers said. view more (2009-10-19)
New type of flying reptile discovered
An international group of researchers from the University of Leicester (UK), and the Geological Institute, Beijing (China) have identified a new type of flying reptile - providing the first clear evidence of an unusual and controversial type of evolution. view more (2009-10-14)
Chinese and American paleontologists discover a new Mesozoic mammal
An international team of paleontologists has discovered a new species of mammal that lived 123 million years ago in what is now the Liaoning Province in northeastern China. view more (2009-10-09)
Homebound termites answer 150-year-old evolution question
Staying at home may have given the very first termite youngsters the best opportunity to rule the colony when their parents were killed by their neighbors. view more (2009-10-06)
Kent State University Professor C. Owen Lovejoy helps unveil oldest hominid skeleton
Throw out all those posters and books that depict an ape evolving into a human being, says Kent State University Professor of Anthropology Dr. C. Owen Lovejoy. view more (2009-10-02)
Pesky fruit flies learn from experienced females: Study
A common household nuisance, the fruit fly, is capable of intricate social learning much like that used by humans, according to new research from McMaster University. view more (2009-09-17)
Secrets in a seed: Clues into the evolution of the first flowers
Approximately 120-130 million years ago, one of the most significant events in the history of the Earth occurred: the first flowering plants, or angiosperms, arose. view more (2009-09-15)
Evolution still scientifically stable
An international team of researchers, including Monash University biochemists, has discovered evidence at the molecular level in support of one of the key tenets of Darwin's theory of evolution. view more (2009-09-14)
Evolution coup: Study reveals how plants protect their genes
Unlike animals and humans, plants can't run and hide when exposed to stressful environmental conditions. So how do plants survive? view more (2009-09-11)
Ancient oceans offer new insight into the origins of animal life
Analysis of a rock type found only in the world's oldest oceans has shed new light on how large animals first got a foothold on the Earth. view more (2009-09-10)
Secrets of the 4 chambers revealed by reptile hearts
The first genetic link in the evolution of the heart from three-chambered to four-chambered has been found, illuminating part of the puzzle of how birds and mammals became warm-blooded. view more (2009-09-03)
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)
