June 4, 2015 — About 10 years ago, someone stumbled across some bones sticking out of a cliff along the Oldman River in southeastern Alberta, Canada. Now, scientists describe that those bones belonged to a nearly ... read more

June 4, 2015 — A fossil's age raises the possibility that the first animals to emerge from the water to live on land were large tetrapods in Gondwana in the southern hemisphere, rather than smaller species in ... read more

June 3, 2015 — About 34 million years ago, global temperatures took a dive, causing a sudden wave of extinctions among European mammals. In North America, however, life went on largely unscathed. A new study ... read more

June 1, 2015 — New research shows that the close linkage between the physical properties of amino acids, the genetic code, and protein folding was likely the key factor in the evolution from building blocks to ... read more

May 28, 2015 — Although scientists are confident that all modern human populations can trace their ancestry back to Africa, the route taken out of Africa is still unclear. New genomic analyses of people currently ... read more

May 22, 2015 — A unique adaptation in the foot of birds is the presence of a thumb-like opposable toe, which allows them to grasp and perch.  However, in their dinosaur ancestors, this toe was small and non- ... read more

May 22, 2015 — Genetic material from fungi collections helped a team of researchers resolve the mushroom 'tree of life,' a map of the relationships between key mushroom species and their evolutionary ... read more

May 22, 2015 — Animals with large brains are considered to be more intelligent and more successful than those with smaller brains. Researchers have now provided the first experimental evidence that large brains ... read more

May 22, 2015 — A new study of some primitive birds from the Cretaceous shows how several separate lineages evolved adaptations for diving. Living at the same time as the dinosaurs, Hesperornithiform bird fossils ... read more

May 21, 2015 — Despite a billion years of evolution separating humans from the baker's yeast in their refrigerators, hundreds of genes from an ancestor that the two species have in common live on nearly ... read more

May 19, 2015 — The original snake ancestor was a nocturnal, stealth-hunting predator that had tiny hindlimbs with ankles and toes, according to new research. Snakes show incredible diversity, with over 3,400 living ... read more

May 12, 2015 — Scientists have successfully replicated the molecular processes that led from dinosaur snouts to the first bird ... read more

May 11, 2015 — When it comes to winning evolutionary fitness races, the tortoise once again prevails over the hare. Scientists have found that limiting migrations among populations of bacteria produced better ... read more

May 7, 2015 — The discovery of a 500-million-year-old fossilized brain has helped identify a point of crucial transformation in early animals, and answered some of the questions about how heads first ... read more

May 7, 2015 — Newly evolved genes can rapidly assume control over fundamental functions during early embryonic development. The findings suggest that evolutionary changes to the genetics of fundamental biological ... read more

May 6, 2015 — Biologists have discovered a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types ... read more

May 6, 2015 — A scientist who discovered a new Scottish flower has made an unexpected second finding that provides unique insight into our understanding of evolution. The original find was made even more rare ... read more

Apr. 30, 2015 — Zebras' vivid pigmentation and the fight or flight instinct. These and other features of the world's vertebrates stem from neural crest cells, but little is known about their origin. ... read more

Apr. 30, 2015 — Scientists have identified the first fossil specimens of a major group of killifishes that is widely distributed in freshwater habitats today. The 6-million-year-old material sheds new light on the ... read more

Evolution: The Secrets of the Brachiopod Shell

Apr. 30, 2015 — Researchers have carried out the first detailed study of the molecular mechanisms responsible for formation of the brachiopod shell. Comparison with shell synthesis in other groups reveals the deep ... read more
