Some Pre-Roman humans were buried with dogs, horses and other animals      (via sciencedaily.com)     Original source 

Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between these humans and animals, or religious sacrificial practices, according to a new study.

Did Eurasia's dominant East-West axis 'turn the fortunes of history'?      (via sciencedaily.com)     Original source 

Jared Diamond proposed that Eurasia's unique geographic axis of orientation fueled a rapid spread of critical innovations among its societies, leading to a cultural and military dominance over other regions. A team of ecologists and cultural evolutionists from the USA, Germany and New Zealand harnessed extensive cultural, environmental and linguistic databases to test these claims. They found that environmental barriers have influenced cultural spread but do not consistently favour Eurasia.

Great apes playfully tease each other      (via sciencedaily.com)     Original source 

Babies playfully tease others as young as eight months of age. Since language is not required for this behavior, similar kinds of playful teasing might be present in non-human animals. Now cognitive biologists and primatologists have documented playful teasing in four species of great apes. Like joking behavior in humans, ape teasing is provocative, persistent, and includes elements of surprise and play. Because all four great ape species used playful teasing, it is likely that the prerequisites for humor evolved in the human lineage at least 13 million years ago.

The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly      (via sciencedaily.com)     Original source 

Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.

Scandinavia's first farmers slaughtered the hunter-gatherer population, study finds      (via sciencedaily.com)     Original source 

Following the arrival of the first farmers in Scandinavia 5,900 years ago, the hunter-gatherer population was wiped out within a few generations, according to a new study. The results, which are contrary to prevailing opinion, are based on DNA analysis of skeletons and teeth found in what is now Denmark.

Innovation in stone tool technology involved multiple stages at the time of modern human dispersals      (via sciencedaily.com)     Original source 

A new study illuminates the cultural evolution that took place approximately 50,000 to 40,000 years ago, coinciding with the dispersals of Homo sapiens across Eurasia. The insights gleaned from their examination of stone tool technology challenge the widely held notion of a rapid cultural and technological 'revolution' that enabled anatomically modern humans to surpass Neanderthals and other archaic humans. Instead, the research suggests a nuanced evolutionary process, unfolding gradually over an extended period, with changes occurring at various times. These findings challenge the conventional theory on the timing and nature of cultural transitions during this pivotal period in human history.

Thailand's Iron Age Log Coffin culture      (via sciencedaily.com)     Original source 

A mortuary practice known as Log Coffin culture characterizes the Iron Age of highland Pang Mapha in northwestern Thailand. Between 2,300 and 1,000 years ago, individuals were buried in large wooden coffins on stilts, mostly found in caves and rock shelters.

Prehistoric mobility among Tibetan farmers, herders shaped highland settlement patterns, cultural interaction, study finds      (via sciencedaily.com)     Original source 

Using advanced geospatial modeling to compare environmental and archaeological evidence, researchers found evidence that connects ancient mobility and subsistence strategies to cultural connections forged among Tibetan farmers and herders in the Bronze and Iron Ages -- adding to understanding of how and why ancient communities built social relationships and cultural identities across the extreme terrain in Tibet.

Neanderthals and humans lived side by side in Northern Europe 45,000 years ago      (via sciencedaily.com)     Original source 

Archaeologists have debated whether Neanderthals or modern humans made stone tools that are found at sites across northern Europe and date from about 40,000 years ago. A new excavation at one site in Germany turned up 45,000-year-old bone fragments that, when analyzed for mitochondrial DNA, proved to be from Homo sapiens. This is the earliest evidence that modern humans overlapped with Neanderthals in northwest Europe, thousands of years before Neanderthals went extinct.

How did humans learn to walk? New evolutionary study offers an earful      (via sciencedaily.com)     Original source 

A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.

Analysis of the remains of 24 individuals from the Wilamaya Patjxa and Soro Mik'aya Patjxa burial sites in Peru shows that early human diets in the Andes Mountains were composed of 80 percent plant matter and 20 percent meat.

Complex green organisms emerged a billion years ago      (via sciencedaily.com)     Original source 

Of all the organisms that photosynthesize, land plants have the most complex form. How did this morphology emerge? A team of scientists has taken a deep dive into the evolutionary history of morphological complexity in streptophytes, which include land plants and many green algae. Their research allowed them to go back in time to investigate lineages that emerged long before land plants existed.

A window into plant evolution: The unusual genetic journey of lycophytes      (via sciencedaily.com)     Original source 

An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics.

Woolly mammoth movements tied to earliest Alaska hunting camps      (via sciencedaily.com)     Original source 

Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the site and archaeological evidence, indicates that early Alaskans likely structured their settlements to overlap with areas where mammoths congregated. Those findings, highlighted in the new issue of the journal Science Advances, provide evidence that mammoths and early hunter-gatherers shared habitat in the region. The long-term predictable presence of woolly mammoths would have attracted humans to the area.

The first assessment of toxic heavy metal pollution in the Southern Hemisphere over the last 2,000 years      (via sciencedaily.com)     Original source 

Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth's atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time capsule, allowing scientists and historians to link Earth's history with that of human societies. In a new study, ice cores from Antartica show that lead and other toxic heavy metals linked to mining activities polluted the Southern Hemisphere as early as the 13th century.
