Prehistoric footwear dating back 6,200 years discovered in a Spanish cave
Prehistoric footwear dating back 6,200 years discovered in a Spanish cave
A pair of shoes thought to be the oldest ever found in Europe are now estimated to be even older than scientists had previously thought. About 20 pairs of sandals found in southern Spain are at least 6,200 years old, while other woven objects found in the cave date back 9,500 years, according to a new study. The scientists used carbon-dating on 76 objects found in the Cueva de los Murciélagos, Albuñol, near Granada, which were originally discovered by miners in the 19th century. The objects are particularly valuable to science because they represent the first direct evidence of certain hunter-gatherer skills, such as weaving, in southern Europe. They are made of wood, reed and esparto grass. The shoes measured about eight inches in length. The study was published in the journal Science Advances by a team from the Universidad de Alcalá (UAH) and the Universitat Autònoma de Barcelona (UAB). Francisco Martínez Sevilla, a researcher at the Prehistory Department of UAH, said: “These are the earliest and widest-ranging assemblage of prehistoric footwear, both in the Iberian Peninsula and in Europe, unparalleled at other latitudes. “The new dating of the esparto baskets from the Cueva de los Murciélagos of Albuñol opens a window of opportunity to understanding the last hunter-gatherer societies of the early Holocene. “The quality and technological complexity of the basketry makes us question the simplistic assumptions we have about human communities prior to the arrival of agriculture in Southern Europe.” He said the project placed the cave as “a unique site in Europe to study the organic materials of prehistoric populations”. Cueva de los Murciélagos, or “Cave of the Bats,” is located on the coast of Granada, to the south of the Sierra Nevada. The finds are thought to have been so well-preserved because of low humidity levels in the area. Study co-author María Herrero Otal added: “The esparto grass objects from Cueva de los Murciélagos are the oldest and best-preserved set of plant fibre materials in Southern Europe so far known. “The technological diversity and the treatment of the raw material documented demonstrates the ability of prehistoric communities to master this type of craftsmanship, at least since 9,500 years ago, in the Mesolithic period. “Only one type of technique related to hunter-gatherers has been identified, while the typological, technological and treatment range of esparto grass was extended during the Neolithic from 7,200 to 6,200 years before the present.” Sign up to our free Indy100 weekly newsletter Have your say in our news democracy.

Scientists unveil shape-changing ‘morphobot’ that can walk, drive, and fly
Scientists unveil shape-changing ‘morphobot’ that can walk, drive, and fly
Scientists have designed a new robot nicknamed “morphobot” that can travel on different terrains, including land and air by shapeshifting its parts into wheels, propellers, or legs as required. Researchers, including Alireza Ramezani from Northeastern University in the US, say the morphobot can transform its shape to navigate the environment by flying, rolling, crawling, crouching, balancing, and tumbling. Several animals have adapted the use of their limbs to allow them to tackle different terrains. Sea lions, for instance, walk on land using their flippers that they also use to swim, and meerkats use their hindlimbs to scout their surroundings. Chukar birds have also shown adaptations to use their wings to walk on all fours up steep inclines. Similarly, the morphobot, described this week in the journal Nature Communications, performs different modes of movement inspired by animals like birds, meerkats, and seals by mimicking the animals’ limb repurposing abilities. The robot, which weighs 6kg (13lb), has four legs each comprising two joints, along with ducted fans fixed at the leg ends. It spans 70cm in length and has a width and height of 35cm. The new study shows that the morphobot’s fans can shapeshift to function either as legs, propellor thrusters, or wheels as required. The robot has demonstrated the ability to alter its movements to walk on rough terrain, traverse steep slopes, tumble over large obstacles, fly to higher levels, and crawl under low-ceiling pathways. Based on the study, researchers say future mobile robots can be designed with multi-functional limbs to navigate complex terrains by adapting their movement strategies. The new innovation could help further improve the design of robots to traverse harsh environments, such as those used in search and rescue responses after natural disasters, space exploration, and automated package delivery. The findings, according to scientists, demonstrate the advantages of designing robots with multipurpose appendages that can be used to travel over varied and challenging terrains.
