A new species of flying reptile reshuffles the timeline of pterosaur evolution
About 230 million years ago, almost 80 million years before the first bird appeared, their distantly related cousins, the pterosaurs took to the sky, as the first group of active fliers among the vertebrates. Pterosaurs developed active, flapping fli.....»»
New research reveals insights into gender equality in hunter-gatherer societies
A study published in the journal Evolution and Human Behaviour has uncovered fascinating insights into gender roles and cooperation in hunter-gatherer societies. The study, entitled "Bargaining between the sexes: outside options and leisure time in h.....»»
3D fossil scans investigate the origins of bipedal locomotion in human evolution
One of the most fascinating periods in the evolution of the human lineage is the appearance of the first ancestors capable of bipedalism. Knowing the type of locomotion used by many fossil species—walking upright on the ground or climbing from bran.....»»
Genetic factors in woodland strawberries promote cold tolerance
Climate change is shifting the seasons, pushing crop plants to their limits. For example, sudden frost episodes in late spring can be detrimental to strawberries in the bed. Wild species, on the other hand, are often more resilient......»»
The Whole Story of How Humans Evolved From Great Apes
The picture of human evolution has changed repeatedly and dramatically over the past half century, shaped by waves of new fossil discovery, technology, and scientific techniques......»»
Fossilized footprints reveal two extinct hominin species living side by side 1.5 million years ago
Human footprints stir the imagination. They invite you to follow, to guess what someone was doing and where they were going. Fossilized footprints preserved in rock do the same—they record instances in the lives of many different extinct organisms,.....»»
A fossil first: Scientists find 1.5-million-year-old footprints of two different species of human ancestors at same spot
More than a million years ago, on a hot savanna teeming with wildlife near the shore of what would someday become Lake Turkana in Kenya, two completely different species of hominins may have passed each other as they scavenged for food......»»
Biologists identify traits correlating with all bird extinctions since 1500
Looking to inform the conservation of critically endangered bird species, University of Utah biologists have completed an analysis identifying traits that correlate with all 216 bird extinctions since 1500......»»
Scientists use acoustic data to track blue and fin whale occurrences in the Arctic
The long-term analysis of blue whale and fin whale vocalizations in the eastern Fram Strait offers valuable insights into seasonal and annual patterns regarding these species' occurrence in the region. For example, blue whales can primarily be heard.....»»
Black Friday, the economic environment and the evolution of America"s retail holiday
On November 29, American shoppers will rush to malls and retail stores for the day known as "Black Friday," the unofficial start of the holiday shopping season. Falling annually on the Friday after Thanksgiving, the event generates billions of dollar.....»»
Brains grew faster as humans evolved, study finds
Modern humans, Neanderthals, and other recent relatives on our human family tree evolved bigger brains much more rapidly than earlier species, a new study of human brain evolution has found......»»
Fruit fly study offers new insights into sperm evolution
Sperm are the most diverse and rapidly evolving cell type. Why sperm have undergone such dramatic evolution is a mystery that has stumped biologists for more than a century......»»
X-ray measurements reveal an unexpected role for copper in photocatalysts
Copper is a promising catalyst for sustainably converting carbon dioxide into substances with more electrons (called reduced species). This is an important step in converting carbon dioxide into fuels. This reaction is often initiated by electrical e.....»»
Ultrawide binary objects in the Kuiper belt may not have come from the earliest solar system, research suggests
Trying to understand the makeup and evolution of the solar system's Kuiper belt has kept researchers busy since it was hypothesized soon after the discovery of Pluto in 1930. In particular, binary pairs of objects there are useful as indicators since.....»»
First right whales of season gorge on critical food off Massachusetts, giving hope for a strong year
Scientists who study a critically endangered species of whale that lives off New England said encouraging early signs suggest the animals could have a strong season for feeding and breeding......»»
Spin-powered crystals dramatically improve water splitting process for clean hydrogen production
Water splitting—breaking water molecules into hydrogen and oxygen—is a promising pathway to sustainable energy. However, this process has long been challenged by the slow chemical kinetics of the oxygen evolution reaction that make hydrogen produ.....»»
Study discovers formation of Criegee intermediates from photochemical oxidation of alkenes
Organic peroxy radicals (RO2) and Criegee intermediates (CI, carbonyl oxides) are key reactive species in atmospheric chemistry and play crucial roles in the formation of secondary organic aerosol (SOA)......»»
International team studies the migration of the American woodcock
The American woodcock, a plump harbinger of spring, is a well known shorebird found across eastern North America. The species is a popular game bird and has earned the admiration of hunters, birders and others through its spring display, whistling wi.....»»
Slender-billed Curlew may be extinct, marking the disappearance of a third bird species from the Western Palaearctic
A small team of conservationists, biodiversity specialists and bird researchers has found that it is likely a third species of bird has gone extinct in the Western Palaearctic—a large area of land spanning parts of North Africa all the way up to po.....»»
New tools filter noise from evolution data
While rates of evolution have appeared to accelerate over short time periods, new analysis suggests that statistical noise is affecting the data patterns. A professor at the University of Tennessee, Knoxville, and his colleague have developed new too.....»»
Apple’s plans for a Siri evolution keep getting pushed into the future
Apple is reportedly working on the next big digital assistant evolution with what it calls LLM Siri. But the upgrade will take its own sweet time to arrive......»»
