Economically, the Solanaceae family is one of the most valuable crop families in the United States, says Collmer. In 1999, about 494,...Tiny trickster flies into the zoological books
...ery is at thatlevel. "The vast majority of species belong to families that had been describedby the start of the 20th Century," said Professor Austin. "Families thathave avoided discovery have done so usually because they are extremelyrare, only found in very isolated places, or very small."

...hers uncovered other fossils that they believe may belong to some of Stromer's lost dinosaur species, as well as fossils from fish, crab, coelacanth, and crocodile-like species. Many of these fossils are giants in their own right, causing Smith and colleagues to speculate on the special nature of the Egypti...First dinosaur found with its body covering intact; displays primitive feathers from head to toe

Dromaeosaurs belong to a group of dinosaurs known as advanced theropods, two-legged predators including Tyrannosaurus rex, with sharp teeth and bones strikingly similar to those of modern-day birds. This fossil radically modifies our vision of these extinct animals, sa...For whales and seals the ocean is not blue

The ancestors of whales were terrestrial artiodactyls (even-toed ungulates), the closest terrestrial relative of the whales is the hippopotamus. Seals have evolved from terrestrial carnivores, among their close relative...Researcher finds that important fungal "scaffolding" genes belong to one of four classes
...that crucial cell scaffold proteins called septins belong to one of four classes. The discovery could help unlock more information about septins, which are found in most animals, including humans, but not in plants. The new classifications may lead to improved ways to treat fungal diseases in humans and co...DNA deletion offers new evidence of mammals' origins

On the other hand, a group known as Archonta should be split apart according to Springer et al. "The molecular data are really convincing that this isn't a group," said DeBry. "Bats are somewhere c...Computer generates comparative gene maps
