Primordial fish had rudimentary fingers
Tetrapods, the first four-legged land animals, are regarded as the first organisms that had fingers and toes. Now researchers at Uppsala University can show that this is wrong. Using medical x-rays, they found rudiments of fingers in the fins in fossil Panderichthys, the "transitional... view more (2008-09-22)

Living fossil roams the seas
Fossil' fish coelacanth, first dragged up along the coast of South Africa in 1938, having been considered extinct for 65 million years. Because of its close resemblance to land animals, it has attracted attention to the subject of a 'missing link' between tetrapods and humans.   view more (2005-07-13)

Quantum dot recipe may lead to cheaper solar panels
Rice University scientists today revealed a breakthrough method for producing molecular specks of semiconductors called quantum dots, a discovery that could clear the way for better, cheaper solar energy panels.   view more (2007-05-03)

Closing the gap between fish and land animals
New exquisitely preserved fossils from Latvia cast light on a key event in our own evolutionary history, when our ancestors left the water and ventured onto land.   view more (2008-06-26)

Four-legged ancestor of land animals found in Europe
In the 19th century a fossil was uncovered in Belgium that was believed to be the jaw of a fish. Now a team of scientists have shown that it is in fact a fossil from an ancestor of all present-day land animals. It is the first discovery of a so-called tetrapod from the Devonian Period in... view more (2004-01-28)

Coelacanth fossil sheds light on fin-to-limb evolution
A 400 million-year-old fossil of a coelacanth fin, the first finding of its kind, fills a shrinking evolutionary gap between fins and limbs.   view more (2007-08-01)

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... view more (2004-11-03)

Found: First lungless frog
Researchers have confirmed the first case of complete lunglessness in a frog, according to a report in the April 8th issue of Current Biology, a publication of Cell Press. The aquatic frog Barbourula kalimantanensis apparently gets all the oxygen it needs through its skin.   view more (2008-04-08)

Recovering from a mass extinction
The full recovery of ecological systems, following the most devastating extinction event of all time, took at least 30 million years, according to new research from the University of Bristol.   view more (2008-01-21)

Gold-tipped nanocrystals developed by Hebrew University researchers
"Nanodumbells" - gold-tipped nanocrystals which can be used as highly-efficient building blocks for devices in the emerging nanotechnology revolution - have been developed by researchers at the Hebrew University of Jerusalem. The technology, developed by a research group headed by Prof.... view more (2004-06-17)

Newly found species fills evolutionary gap between fish and land animals
Paleontologists have discovered fossils of a species that provides the missing evolutionary link between fish and the first animals that walked out of water onto land about 375 million years ago.   view more (2006-04-06)

Giant marine reptiles from Sweden
At the end of the Cretaceous, when large-sized theropods, such as Tyrannosaurus rex, roamed terrestrial environments, shallow seas and oceans were invaded by giant marine monitors - the mosasaurs. A recent investigation, presented in a new dissertation at Lund University in Sweden, has revealed... view more (2004-01-21)

Details of Evolutionary Transition from Fish to Land Animals Revealed
New research has provided the first detailed look at the internal head skeleton of Tiktaalik roseae, the 375-million-year-old fossil animal that represents an important intermediate step in the evolutionary transition from fish to animals that walked on land.   view more (2008-10-16)

Early Land Animals Could Walk and Run Like Mammals, New Study Finds
Salamanders and the tuatara, a lizard-like animal that has lived on Earth for 225 million years, were the first vertebrates to walk and run on land, according to a recent study by Ohio University researchers.   view more (2006-03-09)
