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)
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)
Hind wings help butterflies make swift turns to evade predators, study finds
New tires allow race cars to take tight turns at high speeds. Hind wings give moths and butterflies similar advantages: They are not necessary for basic flight but help these creatures take tight turns to evade predators. view more (2009-01-09)
New moth variety disarms plants guarded by selenium
In new work, researchers report that the ability of plants to defend themselves by accumulating high levels of a toxic element can be overcome by some insects, and that such adaptation potentially echoes in the food web as other predators and parasites may in turn evolve to deal with high levels of the toxic element. view more (2006-11-21)
Sea snails break the law
Lizards gave rise to legless snakes. Cave fishes don't have eyeballs. In evolution, complicated structures often get lost. Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated. view more (2007-04-25)
Meat-eating dinosaur from Argentina had bird-like breathing system
The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina's Rio Colorado is helping to unravel how birds evolved their unusual breathing system. view more (2008-09-30)
The turbidity of wine has an influence on the aroma of the ferment, but not on the accumulation of biogenic amines
The turbidity of red wine during its ageing in oak casks has an influence on the accumulation of volatile compounds and, thereby, on the wine's aroma, but not on the accumulation of biogenic amines. view more (2006-11-28)
How new diseases from insects hit people like the plague
Scientists have traced the first steps in the way some new diseases emerge, and how harmless bacteria living in insects become dangerous disease-causing bugs which can affect humans, like the plague or anthrax. Researchers from the University of Bath are presenting their results today (Wednesday, 08 September 2004) at the Society for General... view more... (2004-08-23)
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...
