Aug. 7, 2015 — The common baker's yeast (Saccharomyces cerevisiae) was the first non-bacterial living thing to have its genome sequenced, back in 1996. However, when the sequence of that genome emerged it ... read more

Aug. 7, 2015 — Researchers have examined one of the smallest parts of the fossil record -- theropod teeth -- to shed light on the evolution of dinosaurs at the end of the Cretaceous. Findings have effectively ... read more

Aug. 6, 2015 — Understanding how and why we evolved such large brains is one of the most puzzling issues in the study of human evolution. A new study argues that carbohydrate consumption, particularly in the form ... read more

Aug. 6, 2015 — An intriguing study involving walking stick insects shows how natural selection, the engine of evolution, can also impede the formation of new ... read more

Aug. 3, 2015 — A new analysis of early hominin body size evolution suggests that the earliest members of the Homo genus (which includes our species, Homo sapiens) may not have been larger than earlier hominin ... read more

Effect of Environmental Epigenetics on Disease, Evolution

Aug. 3, 2015 — Environmental factors are having an underappreciated effect on the course of disease and evolution by prompting genetic mutations through epigenetics, a process by which genes are turned on and off ... read more

July 29, 2015 — An analysis of data on stomach acidity and diet in birds and mammals suggests that high levels of stomach acidity developed not to help animals break down food, but to defend animals against food ... read more

July 28, 2015 — One question of the origin of life in particular remains problematic: what enabled the leap from a primordial soup of individual monomers to self-replicating polymer chains? A new model proposes a ... read more

July 23, 2015 — An "absolutely exquisite" fossil of a snake that had four legs has been discovered by a team of scientists and may help show how snakes made the transition from lizards to ... read more

July 22, 2015 — Animal populations on islands tend to develop weird traits over time, becoming big or small or losing the ability to fly. One less-studied pattern of evolution on islands is the tendency for animal ... read more

July 21, 2015 — Compared to its celestial neighbors Venus and Mars, Earth is a pretty habitable place. So how did we get so lucky? A new study sheds light on the improbable evolutionary path that enabled Earth to ... read more

July 13, 2015 — If not for a single genetic mutation, each kernel on a juicy corn cob would be trapped inside a inedible casing as tough as a walnut shell. The mutation switches one amino acid for another at a ... read more

July 8, 2015 — Scientists have discovered a striking new species of horned dinosaur based on fossils collected from a bone bed in southern Alberta, Canada. Wendiceratops pinhornensis was approximately 6 meters long ... read more

July 3, 2015 — The brain hidden inside the oldest known Old World monkey skull has been visualized for the first time. The ancient monkey, known as Victoriapithecus, first made headlines in 1997 when its 15 ... read more

July 2, 2015 — The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt Arctic life, including skin and hair development, insulin signaling, fat ... read more

How Our Sense of Smell Evolved, Including in Early Humans

July 2, 2015 — A group of scientists has studied how our sense of smell has evolved, and has even reconstructed how a long-extinct human relative would have been able to ... read more

June 30, 2015 — While studying Yersinia pestis, the bacteria responsible for epidemics of plague such as the Black Death, scientists found a single small genetic change that fundamentally influenced the evolution of ... read more

June 24, 2015 — A tiny tooth plate of the 410 million year old fossil fish Romundina stellina indicates that teeth evolved earlier in the tree of life than recently thought. Jaws and teeth have been important ... read more

June 22, 2015 — In 1964, renowned biologists Peter Raven and Paul Erhlich published a landmark study that introduced the concept of co-evolution. Now, an international team of researchers has used genomics to ... read more

June 22, 2015 — Genetic analysis of a 40,000-year-old jawbone from Romania reveals that early modern humans interbred with Neanderthals when they first came to ... read more
