Trouble With Parasites? Just Migrate

May 27, 2016 — A new model has been designed to explore whether combating infection could, in theory, be a potential benefit of ... read more

May 19, 2016 — In a first-of-its kind study, scientists have found that a majority of professors teaching biology in Arizona universities do not believe that helping students accept the theory of evolution is an ... read more

May 19, 2016 — In the bird world, the color red has special significance. Many species use red signals to attract mates or deter rivals, adding the color to their beaks, feathers, or bare skin. As far as many birds ... read more

May 19, 2016 — A key gene has been found that assisted the transition of plants from water to the land around 500 million years ago. The ANR gene is required to tolerate 'extreme dehydration' in the moss ... read more

May 19, 2016 — If you're a rattlesnake, you want to bring the right weapon to a squirrel fight. And that venomous weapon varies from place to place, evolutionarily calibrated to overpower the local ... read more

May 19, 2016 — Scientists have demonstrated that hawk moths acquired the highest energy gain when they visited flowers that matched the length of their proboscis. The moths were supported in their choice of the ... read more

May 18, 2016 — A new study demonstrates the evolution of protein structure and function over 3.8 billion years. Snippets of genetic code, consistent across organisms and time, direct proteins to create ... read more

May 17, 2016 — Biological evolution was preceded by a long phase of chemical evolution during which precursors of biopolymers accumulated. Chemists have discovered an efficient mechanism for the prebiotic synthesis ... read more

May 17, 2016 — For the first time, the genomes of the giraffe and its closest living relative, the reclusive okapi of the African rainforest, have been sequenced -- revealing the first clues about the genetic ... read more

May 17, 2016 — Mitochondria are the power stations of human cells. They provide the energy needed for the cellular metabolism. But how did these power stations evolve, and how are they constructed? Researchers ... read more

May 16, 2016 — A contagious form of cancer that can spread between dogs during mating has highlighted the extent to which dogs accompanied human travelers throughout our seafaring history. But the tumors also ... read more

May 12, 2016 — Same-sex sexual behavior is common in animals but puzzles evolutionary biologists since it doesn't carry the same obvious benefits as heterosexual courtship behavior that leads to mating and ... read more

May 12, 2016 — A new study of the genetic factors underlying glioma formation in dogs may hold clues to how these common and often untreatable tumors form in humans. The genome study, which was conducted across 25 ... read more

When Fungus Foes Become Friends

May 12, 2016 — A few modifications in the genome turn a fungal plant pathogen into a potentially beneficial ... read more

Cooperation, Not Struggle for Survival, Drives Evolution, Say Researchers

May 12, 2016 — Using a new conceptual evolutionary model, investigators have reviewed the debated mechanism of speciation, suggesting that competition and a struggle for the existence are not the main drivers of ... read more

May 12, 2016 — Over their 52-million-year history, a few bats have evolved a taste for their fellow vertebrates. Now biologists are shedding light on how these so-called 'carnivorous bats' adapted to the ... read more

Fluorescent Jellyfish Gene Sheds Light on 'Fitness Landscape'

May 12, 2016 — By studying more than 50,000 variants of a jellyfish gene, researchers have drawn a detailed picture of how changes in that gene affect its ... read more

Do You See What I See? Study Shows Development of Gaze Following in Monkeys Is Similar to Humans

May 11, 2016 — Gaze following in monkeys develops in a way that's nearly identical to humans, suggesting that the behavior has deep evolutionary roots, new research ... read more

May 11, 2016 — A genome-wide association analysis of over 1,000 twins in the UK supports that some parts of our microbiomes are inherited and shaped -- not through a spread of microbes from parent to child, but ... read more

May 10, 2016 — The discovery of a deep-water seaweed that evolved into a multi-cellular plant more than 540 million years ago has added a new branch to the tree of life, according to ... read more
