Interspecies competition led to even more forms of ancient human -- defying evolutionary trends in vertebrates      (via sciencedaily.com)     Original source 

Competition between species played a major role in the rise and fall of hominins -- and produced a 'bizarre' evolutionary pattern for the Homo lineage -- according to a new study that revises the start and end dates for many of our early ancestors.

Evolution's recipe book: How 'copy paste' errors cooked up the animal kingdom      (via sciencedaily.com)     Original source 

A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste' errors allowed animals to keep one copy of their genome or genes for fundamental functions, while the second copy could be used as raw material for evolutionary innovation. Events like these, at varying degrees of scale, occurred constantly throughout the bilaterian evolutionary tree and enabled traits and behaviours as diverse as insect flight, octopus camouflage and human cognition.

Pacific cities much older than previously thought      (via sciencedaily.com)     Original source 

New evidence of one of the first cities in the Pacific shows they were established much earlier than previously thought, according to new research. The study used aerial laser scanning to map archaeological sites on the island of Tongatapu in Tonga, showing Earth structures were being constructed in Tongatapu around AD 300.

The hidden role of the Milky Way in ancient Egyptian mythology      (via sciencedaily.com)     Original source 

Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.

Birdfeeders are designed to keep unwanted guests away      (via sciencedaily.com)     Original source 

The first birdfeeders were made in the 19th century, and their design rapidly evolved during the 20th century. Researchers at the consider the evolution of the birdfeeder to be an example of multispecies design, where unwanted guests have shaped the human-made artifact.

Subterranean storage of hydrogen      (via sciencedaily.com)     Original source 

Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.

Finds at Schöningen show wood was crucial raw material 300,000 years ago      (via sciencedaily.com)     Original source 

During archaeological excavations in the Schoningen open-cast coal mine in 1994, the discovery of the oldest, remarkably well-preserved hunting weapons known to humanity caused an international sensation. Spears and a double-pointed throwing stick were found lying between animal bones about ten meters below the surface in deposits at a former lakeshore. In the years that followed, extensive excavations have gradually yielded numerous wooden objects from a layer dating from the end of a warm interglacial period 300,000 years ago. The findings suggested a hunting ground on the lakeshore.

When did the chicken cross the road? New evidence from Central Asia      (via sciencedaily.com)     Original source 

An international team of scholars present the earliest clear archaeological and biomolecular evidence for the raising of chickens for egg production, based on material from 12 archaeological sites spanning one and a half millennia. The research indicates that the domestic chicken, now a staple in diets around the world, is not as ancient as previously thought.

Mosquito detectives track malaria's history      (via sciencedaily.com)     Original source 

A group of researchers is calling on colleagues around the world to join them in what they call 'pathogen prospecting' by tracking down archival specimens of mosquitoes in museums and other collections to examine them for pathogens that would have infected people with malaria while feeding on their blood.

Ancient DNA reveals the appearance of a 6th century Chinese emperor      (via sciencedaily.com)     Original source 

What did an ancient Chinese emperor from 1,500 years ago look like? A team of researchers reconstructed the face of Chinese Emperor Wu of Northern Zhou using DNA extracted from his remains. The study suggests the emperor's death at the age of 36 might be linked to a stroke. It also sheds light on the origin and migration patterns of a nomadic empire that once ruled parts of northeastern Asia.

DNA study IDs descendants of George Washington from unmarked remains, findings to aid service member IDs going back to World War II      (via sciencedaily.com)     Original source 

New DNA sequencing technologies have identified the historical remains of George Washington's grandnephews, Samuel Walter Washington and George Steptoe Washington Jr., and their mother, Lucy Payne Washington, from unmarked, fragmentary bones left at the Harewood family cemetery in Charles Town, West Virginia, in the mid-1800s.

For centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.

Persian plateau unveiled as crucial hub for early human migration out of Africa      (via sciencedaily.com)     Original source 

A new study combining genetic, palaeoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa. It highlights the period between 70,000 to 45,000 years ago when human populations did not uniformly spread across Eurasia, leaving a gap in our understanding of their whereabouts during this time frame.
