Independent evolutionary origins of vertebrate dentitions
The origins of a pretty smile have long been sought in the fearsome jaws of living sharks which have been considered living fossils reflecting the ancestral condition for vertebrate tooth development and inference of its evolution. However, this view.....»»
New database covers distribution and evolutionary history of megadiverse flowering plant family on isolated islands
Asteraceae, a family of flowering plants, are the most diverse group of flowering plants in the world. This plant family comprises about 34,000 species. An international research team with the participation of the University of Göttingen has now com.....»»
Independent origins of frog glue and its role in predator evasion
Skin-secreted adhesives, or glues, are highly effective defense adaptations that have evolved recurrently in a small number of amphibians. From an ecological standpoint, this rapidly solidifying material—essentially, a sticky slime—encumbers the.....»»
Genetic tracing at the Huanan Seafood market further supports COVID animal origins
A new international collaborative study provides a list of the wildlife species present at the market from which SARS-CoV-2, the virus responsible for the COVID-19 pandemic, most likely arose in late 2019. The study is based on a new analysis of meta.....»»
Can toddlers help explain the origins of our bias for wealth?
Income and wealth inequality in the U.S. remain near all-time highs. Analysts say this disparity is a "major issue of our time." Experts have spotlighted deep policy failures fueling the problem and helpful economic fixes to alleviate the suffering......»»
Understanding the Origins of Life on Earth Could Help Find Life beyond It
We can’t yet tell how life got its start on Earth. That’s one great reason to keep looking for life elsewhere.....»»
Paleontologists find omnivorous ancestor of the giant panda, revealing it was not always just a bamboo eater
The Hammerschmiede fossil site in southern Germany has yielded finds from about 11.5 million years ago that have rewritten evolutionary history. The sole species of bear discovered to date at the site was a relative of the giant panda. Its diet, howe.....»»
New technique boosts mutation rates in fruit flies for genetics research
A new technique, TF-High-Evolutionary (TF-HighEvo), allows large-scale assessment of de-novo mutations in multicellular organisms. Developed in collaboration with researchers from the European Molecular Biology Laboratory (EMBL) and the Friedrich Mie.....»»
An evolutionary battleground: Plants vs. microbes
Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can grow so fast that they can d.....»»
New fossil fish species scales up evidence of Earth"s evolutionary march
Climate change and asteroids are linked with animal origin and extinction—and plate tectonics also seems to play a key evolutionary role, "groundbreaking" new fossil research reveals......»»
International team decodes the genome of the Greenland shark
The Greenland Shark (Somniosus microcephalus), an elusive dweller of the depths of the northern Atlantic and the Arctic Ocean, is the world's longest-living vertebrate, with an estimated lifespan of about 400 years......»»
Long stems on flowers are an adaptation that encourages bat pollination, research suggests
Flowers that are pollinated by bats tend to have long stems that make them stand out from the surrounding foliage. New research published in New Phytologist reveals the evolutionary advantage that this characteristic provides to plants to ensure that.....»»
Protecting just 0.7% of world"s land could help save a third of unique and endangered species
Conservation efforts directed towards just 0.7% of the world's land mass could help protect one third of the world's threatened and unique tetrapod (four-limbed vertebrate) species, new research by Imperial College London, On the Edge, and ZSL has sh.....»»
Massive merger: Study reveals evidence for origin of supermassive black hole at galaxy"s center
The origins of aptly named supermassive black holes—which can weigh in at more than a million times the mass of the sun and reside in the center of most galaxies—remain one of the great mysteries of the cosmos......»»
AI shines a new light on exoplanets
Researchers from LMU, the ORIGINS Excellence Cluster, the Max Planck Institute for Extraterrestrial Physics (MPE), and the ORIGINS Data Science Lab (ODSL) have made an important breakthrough in the analysis of exoplanet atmospheres......»»
"Some pterosaurs would flap, others would soar"—new study confirms flight capability of these giants of the skies
Some species of pterosaurs flew by flapping their wings while others soared like vultures, demonstrates a new study published in the Journal of Vertebrate Paleontology......»»
Unraveling the evolutionary secrets of how whales and dolphins adapted their backbones for aquatic life
If you've ever seen a dolphin swim, you may have wondered why they undulate their bodies up and down when swimming, instead of side to side as fishes do. Though they have a fishlike body, cetaceans (a group comprised of whales, dolphins, and porpoise.....»»
Can we really reach net zero by 2050? A new report maps out Australia"s path in more detail than ever before

Study links gentrification to reduced crime, but downsides of gentrification can"t be ignored
Neighborhood gentrification in Buffalo between 2011 and 2019 was associated with a decrease in property crime, independent of a general decrease in similar crime city-wide during those same years, according to a University at Buffalo study......»»
Wood charcoal reveals the existence of a variety of woody plants around early millet sites

Darwin"s fear was unjustified: Study suggests fossil record gaps not a major issue
Fossils are used to reconstruct evolutionary history, but not all animals and plants become fossils and many fossils are destroyed before we can find them (e.g., the rocks that contain the fossils are destroyed by erosion). As a result, the fossil re.....»»
