Aug. 18, 2015 — A cooling, drying climate over the last 40 million years turned North America from a warm and wooded place into the drier, open plains we know today. A new study shows how dogs evolved in response to ... read more

Aug. 18, 2015 — A study of catsharks reveals how alterations in the expression and function of certain genes in limb buds underlie the evolution of fish fins to limbs. The findings give new insight into how fish ... read more

Aug. 17, 2015 — Paleobotanists in Europe have identified a 125 million- to 130 million-year-old freshwater plant as one of earliest flowering plants on ... read more

Aug. 12, 2015 — Computer scientists have found that robots evolve more quickly and efficiently after a virtual mass extinction modeled after real-life disasters such as the one that killed off the dinosaurs. Beyond ... read more

Aug. 12, 2015 — Competition played a more important role in the evolution of the dog family (wolves, foxes, and their relatives) than climate change, shows a new international study. Researchers analyzed over 2000 ... read more

Aug. 11, 2015 — The evolutionary loss of the 'altruistic' worker caste in ants is not accompanied by a loss of genes, an international team of researchers has found. The results reported in this new ... read more

Mass Extinction Survival Is More Than Just a Numbers Game

Aug. 11, 2015 — Widespread species are at just as high risk of being wiped out as rare ones after global mass extinction events, says new research by UK ... read more

Aug. 10, 2015 — A lizard lineage which has evolved over the last 19 million years has helped scientists to re-think one of the most important concepts of modern biology: adaptive ... read more

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 — By looking closely at DNA variation across a vast number of populations, researchers now have a better idea of how selection affects the human genome around the ... 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

Expanding the Theory of Evolution

Aug. 4, 2015 — An international team of biologists is working to expand Darwin's theory of evolution to encompass factors that influence a species' growth and development beyond genetics -- as well as to ... 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 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
