Genes in Albino Orchids May Hold Clues to Parasitic Mechanism Used by Non-Photosynthetic Plants

Feb. 14, 2017 — How do plants give up photosynthesis and become parasites? A research team is using comprehensive analysis of gene expression in albino and green orchids to investigate the evolution of parasitic ... read more

Feb. 13, 2017 — Biological invasions pose major threats to biodiversity, but little is known about how evolution might alter their impacts over time. Now, Rutgers University scientists have performed the first study ... read more

Feb. 10, 2017 — No less than 500 new species of cichlids, brightly coloured perch-like fish, evolved in Lake Victoria (East Africa) over the past 15,000 years -- a record in the animal and plant world. This ... read more

Feb. 9, 2017 — Changing environments and ecosystems were driving the evolution of horses over the past 20 million years. This is the main conclusion of a new study by paleontologists. The team analyzed 140 species ... read more

Feb. 9, 2017 — Using quantitative approaches from physics, biophysicists discovered a surprising way that bacteria can evolve resistance to antibiotics. After evolving a sleeping mechanism, the bacteria can then ... read more

Feb. 9, 2017 — Researchers have identified a genetic signature found exclusively in the nerve cells that supply, or innervate, the muscles of an organism's outermost extremities: the hands and feet. The ... read more

Feb. 9, 2017 — Fish embryo study indicates that the last common ancestor of vertebrates was a complex animal complete with gills -- overturning prior scientific understanding and complementing recent fossil finds. ... read more

Feb. 8, 2017 — An investigation into the evolution of human walking by looking at how chimpanzees walk on two legs is the subject of a new research ... read more

Rethink Needed to Save Critically Endangered Black Rhinoceros

Feb. 8, 2017 — A new strategy of conservation must be adopted if the black rhinoceros is to be saved from extinction, concludes a new ... read more

Feb. 7, 2017 — The swarm of 237 weevils in a single genus inhabiting Macaronesia is the result of a blend of adaptive and non-adaptive evolution in old volcanic archipelagos. It is the specificity of their isolated ... read more

Genomes in Flux: New Study Reveals Hidden Dynamics of Bird and Mammal DNA Evolution

Feb. 6, 2017 — Evolution is often thought of as a gradual remodeling of the genome, the genetic blueprints for building an organism. But in some instance it might be more appropriate to call it an overhaul. Over ... read more

Feb. 6, 2017 — A new study probes the origins of carnivory in several distantly related plants -- including the Australian, Asian and American pitcher plants, which appear strikingly similar to the human (or ... read more

Feb. 6, 2017 — A 480-million-year-old slug-like fossil has been uncovered in Morocco, shedding new light on the evolution of molluscs -- a diverse group of invertebrates that includes clams, snails and ... read more

Study Finds Mutual Reinforcement of Phenotypic Diversity and Cooperation

Feb. 3, 2017 — A new model exploring how evolutionary dynamics work in natural selection has found that phenotypic diversity, or an organism's observable traits, co-evolves with contingent cooperation when ... read more

Feb. 2, 2017 — A genetic analysis of mosquito populations in Africa shows that recent successes in controlling malaria through treated bednets has led to widespread insecticide resistance in mosquitoes, according ... read more

Feb. 2, 2017 — A low level of atmospheric oxygen in Earth's middle ages held back evolution for 2 billion years, raising fresh questions about the origins of life on this planet. New research explains how ... read more

Feb. 2, 2017 — Data shows new information about the evolution of bird beaks, report scientists. In their study, 3D scans were logged online by members of the public across the ... read more

Jan. 31, 2017 — A Japanese research team has discovered an evolutionary model for the biological function that creates carbon dioxide from glucose in photosynthesis. They found the mechanism in a primitive, ... read more

Yeast Mutants Unlock the Secrets of Aging

Jan. 31, 2017 — Researchers take a closer look into what delaying and accelerating yeast genes might mean for ... read more

Jan. 31, 2017 — Increasingly popular techniques that infer species boundaries in animals and plants solely by analyzing genetic differences are flawed and can lead to inflated diversity estimates, according to a new ... read more
