Did neanderthals use glue? Researchers find evidence that sticks      (via sciencedaily.com)     Original source 

Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.

A new design for quantum computers      (via sciencedaily.com)     Original source 

Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator -- a specific type of quantum computer -- could lead to new discoveries about how the world works at the smallest scales. Quantum scientists have developed a guide on how to upgrade these machines so that they can simulate even more complex quantum systems.

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.

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.

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.

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.

Paleolithic humans may have understood the properties of rocks for making stone tools      (via sciencedaily.com)     Original source 

Research suggests that Paleolithic humans in the Middle East selected flint for their cutting tools based on differences in the mechanical properties of the rock. They seem to have purposefully selected the most suitable rocks for fashioning into tools, even being able to distinguish rocks that were unsuitable.

A mixed origin made maize successful      (via sciencedaily.com)     Original source 

Maize is one of the world's most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research shows that all modern maize descends from a hybrid created just over 5000 years ago in central Mexico, thousands of years after the plant was first domesticated.

Dishing the dirt on human evolution: Why scientific techniques matter in archaeology      (via sciencedaily.com)     Original source 

Scientists should seek answers hidden in the dirt using proven and state-of-the-art archaeological science techniques to support new discoveries about human evolution following recent controversies at a cave site in Africa, says a group of international experts. Their recommendations follow claims published in June of this year that Homo naledi --a small-brained human species -- buried their dead in Rising Star Cave, South Africa, between 335,000 and 241,000 years ago, and may also have decorated the cave walls with engravings.

No scientific evidence for cognitively advanced behaviors and symbolism by Homo naledi      (via sciencedaily.com)     Original source 

A new study casts doubt on claims that Homo naledi, a small-brained hominin dating to between 335-241,000 years ago, deliberately buried their dead and produced rock art in Rising Star Cave, South Africa. Recent articles suggested the recent excavations at the Rising Star Cave system provided evidence of at least three burial features, two in the Dinaledi Chamber and a third in the Hill Antechamber cavity. The group of experts have now called for a deeper dig into the science behind the findings.
