How Natural Selection Acted on One Penguin Species Over the Past Quarter Century

University of Washington biologist Dee Boersma and her colleagues combed through 28 years' worth of data on Magellanic penguins to search for signs that natural selection — one of the main drivers of evolution — may be acting on certain penguin traits.

Bizarre New Species of Extinct Reptile Shows Dinosaurs Copied Body, Skull Shapes of Distant Relatives

Presidential Debate: Expert Panel Gives Scientific Analysis of Candidates' Performances

Four expert panelists each day will present their analyses and answer your questions live and face-to-face. This event will be virtual. You can attend with any device -- PC, Mac, iPad, iPhone or Android device (with a webcam) – anywhere with good bandwidth. To participate (ask questions) in the meeting, you must be on video, just as a normal news conference. Register below for guaranteed seating; there is limited seating in the virtual room. Eight experts (four at each event) will present their analyses. The diverse expert team (7 universities and an institute) will analyze both candidates during the debates for their gestures, facial expressions (including smiles--number, type, appropriateness, etc.), posture, language, including sentiment, tone, inflammatory language, repetition, vocabulary, sentence structure, metaphors, framing, themes, suggestions, subtlety, nuance, honesty (deceit/lies—explicit and implicit), transparency, gender issues, and more...

The Origin of Life: RNA World Deep Beneath the Surface

With support from NASA, researchers at Rensselaer Polytechnic Institute are exploring whether RNA could have formed on early Earth deep beneath the ocean's surface or deep underground.

A Rare Small Specimen Discovered From the Age of Flying Giants

A rare small-bodied pterosaur, a flying reptile from the Late Cretaceous period approximately 77 million years ago, is the first of its kind to have been discovered on the west coast of North America.

Smarter Brains Are Blood-Thirsty Brains

A University of Adelaide-led project has overturned the theory that the evolution of human intelligence was simply related to the size of the brain ─ but rather linked more closely to the supply of blood to the brain.

Monkeys in Zoos Have Human Gut Bacteria

RedshankeddoucLargephoto.jpg

A new study led by the University of Minnesota shows that monkeys in captivity lose much of their native gut bacteria diversity and their gut bacteria ends up resembling those of humans. The results suggest that switching to a low-fiber, Western diet may have the power to deplete most normal primate gut microbes in favor of a less diverse set of bacteria.

New Species of Pterosaur Discovered in Patagonia

Scientists today announced the discovery of a new species of pterosaur from the Patagonia region of South America. The researchers have named this new species ‘ Allkauren koi’ from the native Tehuelche word ‘all’ for ‘brain’, and ‘karuen’ for ‘ancient’.

Looking to Saliva to Gain Insight on Evolution

There’s no need to reinvent the genetic wheel. That’s one lesson of a new study that looks to the saliva of humans, gorillas, orangutans, macaques and African green monkeys for insights into evolution. The research is published today (Aug. 25) in Scientific Reports.

Darwin's Theory About 'Impassable' Marine Barrier Holds True for Coral Larvae in the Pacific

122447_web.jpg

MIAMI--An international team of scientists used a state-of-the-art computer model, a high-powered supercomputer, and five billion 'virtual' coral larvae to test Charles Darwin's 1880 hypothesis that marine species cannot cross the Eastern Pacific's "impassable" marine barrier. The team, which included University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science Associate Professor Claire Paris, found that Darwin's theory still hold true today even under extreme El Niño conditions known to speed up ocean currents.

Genetically Speaking, Blue-Winged and Golden-Winged Warblers Are Almost Identical

WingedWarblers-Fuller.jpg

New research from the Cornell Lab of Ornithology’s Fuller Evolutionary Biology Program shows that, genetically speaking, blue-winged and golden-winged warblers are almost identical. Scientists behind the research say the main differences between the two species are in feather color and pattern, in some cases just a simple matter of dominant or recessive pairings of gene variants, or alleles.

'Cyclops' Beetles Hint at Solution to 'Chicken-and-Egg' Problem in Novel Trait Evolution

Beetles with cyclops eyes have given Indiana University scientists insight into how new traits may evolve through the recruitment of existing genes -- even if these genes are already carrying out critical functions.

New Techniques Boost Understanding of How Fish Fins Became Fingers

The cells that make fin rays in fish play a central role in forming the fingers and toes of four-legged creatures, one of the great transformations required for the descendants of fish to become creatures that walk on land.

Reinterpreting the Fossil Record on Jaws

ravosa_300.jpg

Scientists use the fossil record to make judgments on the physiology and behavior of species. But are those interpretations correct? New research from the University of Notre Dame puts into question how we interpret the behavior of extinct organisms from their fossil remains, and the greater role of plasticity in determining evolution diversity.

On the Prowl for an Elusive Rodent Called ‘the Ultimate Pokémon’

Zenkerella_1.jpg

Researchers are on a real-life search for what one calls “the ultimate Pokémon”: Zenkerella, an elusive scaly-tailed squirrel that has never been spotted alive by scientists. However, biologists recently found three newly dead specimens that hint at how the “living fossil” has evolved over the past 49 million years.

Scientists at The Scripps Research Institute have created a ribozyme that can basically serve both to amplify genetic information and generate functional molecules, a big step toward the laboratory re-creation of the “RNA world,” generally believed to have preceded modern life forms based on DNA and proteins.
