Some 125,000 years ago, enormous elephants that weighed as much as eight cars each roamed in what’s now northern Europe.

Scientifically known as Palaeoloxodon antiquus, the towering animals were the largest land mammals of the Pleistocene, standing more than 13 feet (4 meters) high. Despite this imposing size, the now-extinct straight-tusked elephants were routinely hunted and systematically butchered for their meat by Neanderthals, according to a new study of the remains of 70 of the animals found at a site in central Germany known as Neumark-Nord, near the city of Halle.

The discovery is shaking up what we know about how the extinct hominins, who existed for more than 300,000 years before disappearing about 40,000 years ago, organized their lives. Neanderthals were extremely skilled hunters, knew how to preserve meat and lived a more settled existence in groups that were larger than many scholars had envisaged, the research has suggested.

A distinct pattern of repetitive cut marks on the surface of the well-preserved bones — the same position on different animals and on the left and right skeletal parts of an individual animal — revealed that the giant elephants were dismembered for their meat, fat and brains after death, following a more or less standard procedure over a period of about 2,000 years. Given a single adult male animal weighed 13 metric tons (twice as much as an African elephant), the butchering process likely involved a large number of people and took days to complete.

Stone tools have been found in northern Europe with other straight-tusked elephant remains that had some cut marks. However, scientists have never had clarity on whether early humans actively hunted elephants or scavenged meat from those that died of natural causes. The sheer number of elephant bones with the systematic pattern of cut marks put this debate to rest, said the authors of the study published Wednesday in the journal Science Advances.

The Neanderthals likely used thrusting and throwing spears, which have been found at another site in Germany, to target male elephants because of their larger size and solitary behavior, said study coauthor Wil Roebroeks, a professor of Paleolithic archaeology at Leiden University in Germany. The demographics of the site skewed toward older and male elephants than would be expected had the animals died naturally, according to the study.

“It’s a matter of immobilizing these animals or driving them into muddy shores so that their weight works against them,” he said. “If you can immobilize one with a few people and corner them into an area where they get stuck. It’s a matter of finishing them off.”

What was most startling about the discovery was not that Neanderthals were capable of hunting such large animals but that they knew what to do with the meat, said Britt M. Starkovich, a researcher at the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen in Germany, in commentary published alongside the study.

“The yield is mindboggling: more than 2,500 daily portions of 4,000 calories per portion. A group of 25 foragers could thus eat a straight-tusked elephant for 3 months, 100 foragers could eat for a month, and 350 people could eat for a week,” wrote Starkovich, who was not involved in the research.

“Neanderthals knew what they were doing. They knew which kinds of individuals to hunt, where to find them, and how to execute the attack. Critically, they knew what to expect with a massive butchery effort and an even larger meat return.”

The Neanderthals living there likely knew how to preserve and store meat, perhaps through the use of fire and smoke, Roebroeks said. It’s also possible that such a meat bonanza was an opportunity for temporary gatherings of people from a larger social network, said study coauthor Sabine Gaudzinski-Windheuser, a professor of prehistoric and protohistoric archaeology at the Johannes Gutenberg-University in Mainz, Germany.

She explained the occasion could perhaps have served as a marriage market. An October 2022 study based on ancient DNA from a small group of Neanderthals living in what’s now Siberia suggested that women married outside their own community, noted Gaudzinski-Windheuser, who is also director of the Monrepos Archaeological Research Centre and Museum of Human Behavioural Evolution in Neuwied.

“We don’t see that in the archaeological record but I think the real benefit of this study is that now everything’s on the table,” she said.

Scientists had long thought that Neanderthals were highly mobile and lived in small groups of 20 or less. However, this latest finding suggested that they may have lived in much bigger groups and been more sedentary at this particular place and time, when food was plentiful and the climate benign. The climate at the time — before the ice sheets advanced at the start of the last ice age around 100,000 to 25,000 years ago — would have been similar to today’s conditions.

Killing a tusked elephant would not have been an everyday event, the study found, with approximately one animal killed every five to six years at this location based on the number found. It’s possible, however, that more elephant remains were destroyed as the site is part of a open cast mine, according to the researchers. Other finds at the site suggested Neanderthals hunted a wide array of animals across a lake landscape populated by wild horses, fallow deer and red deer.

More broadly, the study underscores the fact that Neanderthals weren’t brutish cave dwellers so often depicted in popular culture. In fact, the opposite is true: They were skilled hunters, understood how to process and preserve food, and thrived in a variety of different ecosystems and climates. Neanderthals also made sophisticated tools, yarn and art, and they buried their dead with care.

“To the more recognizably human traits that we know Neanderthals had — taking care of the sick, burying their dead, and occasional symbolic representation — we now also need to consider that they had preservation technologies to store food and were occasionally semi sedentary or that they sometimes operated in groups larger than we ever imagined,” Starkovich said.

Our ancestors may have evolved to walk upright in trees rather than on the ground, new study suggests



CNN
 — 

Humans’ ability to walk upright on two legs may have evolved in trees, rather than on the ground, according to scientists studying wild chimpanzees in Tanzania.

This contradicts the widely accepted theory that prehistoric human relatives evolved to walk on two legs because they lived in an open savanna environment, according to a study published Wednesday in the journal Science Advances.

Researchers from University College London (UCL) spent 15 months looked at the behavior of 13 wild adult chimpanzees in the Issa Valley in western Tanzania, which is home to a mixture of dry open land and areas of dense forest. Known as “savanna-mosaic,” this type of environment is similar to that in which our earliest human ancestors lived.

The team recorded every time that the chimpanzees were upright, and whether it occurred while they were on the ground or in the trees.

They then compared this with instances of standing on two legs by chimpanzees that live in densely forested areas in other parts of Africa, and found that the Issa Valley chimpanzees spent just as much time in the trees as their forest-dwelling cousins.

This means they were not more land-based, as existing theories suggest they ought to be, given the more open environment in which they live. In addition, more than 85% of the times that the chimpanzees walked upright occurred in the trees, rather than on the ground.

Study coauthor Alex Piel, an associate professor of anthropology at UCL, told CNN that widely held theories follow a certain logic.

“A long-held assumption has been: Less trees means more time on the ground, more time on the ground means more time upright,” Piel said.

However, his team’s data does not bear that out, instead suggesting that more open environments were not a catalyst in encouraging bipedalism, said Piel. “It’s not this nice logical story,” he said.

The next question for researchers is why the Issa Valley chimpanzees spend more time in trees despite being around fewer trees than other chimpanzee communities, Piel said.

One explanation could be the fact that food-producing trees encourage them to spend time there to eat, he said, while there could also be a seasonal component.

In the rainy season, grass in the Issa Valley grows to around 6.5 feet in height, said Piel, which means the chimpanzees are more vulnerable to ambush predators such as leopards if they spend time on the ground.

“It could be that there is a dramatic seasonal signature to this,” he said.

Early human ancestors would also have faced predation in a similar environment, according to Piel.

“It’s a really analogous system,” he said.

However, Piel underlined that the study is not drawing a direct comparison between the chimpanzees and our early human ancestors, but is instead providing theories that need to be tested against the fossil record to see what it tells us about the anatomy of early hominids.

Meet the International Space Station’s new diverse crew

 — 

When astronauts venture aboard the International Space Station, they see a world without borders. They work together while orbiting Earth, and no boundaries are visible between them, even as member countries contend with geopolitics on the planet below.

This week, a SpaceX Crew Dragon spacecraft with a diverse crew lifted off from Kennedy Space Center in Florida.

The capsule carried NASA astronauts Nicole Mann and Josh Cassada, astronaut Koichi Wakata of the Japan Aerospace Exploration Agency, and cosmonaut Anna Kikina of Roscosmos — the first Russian to travel on a SpaceX spaceflight.

“We live in the same world, we live in the same universe,” Cassada said. “Sometimes we experience it in a very different way from our neighbors. We can all keep that in mind … and continue to do amazing things. And do it together.”

The NASA SpaceX Crew-5 mission, now safely ensconced on the space station, is one of firsts.

Nicole Aunapu Mann is the first Native American woman to go to space as well as the first woman to serve as mission commander for a SpaceX mission.

Mann grew up in Northern California and is a registered member of the Wailacki tribe of the Round Valley reservation. She has been a pilot and colonel in the US Marine Corps. But it wasn’t until her mid-20s that she realized she wanted to be an astronaut and that it was even possible.

“I realized that being an astronaut was not only something that was a possible dream but actually something that’s quite attainable,” Mann said. “I think as a young girl, I just didn’t realize that that was an opportunity and a possibility.”

A monster tsunami rippled across the planet when a dinosaur-killing asteroid crashed into Earth 66 million years ago.

The impact caused 75% of animal and plant life to go extinct and created a chain of cataclysmic events.

Waves more than a mile high pushed away from the impact crater near Mexico’s Yucatan Peninsula and scoured the ocean floor thousands of miles away from the asteroid strike. The tsunami was thousands of times more energetic than those generated by earthquakes.

Sediment cores also showed that the tsunami’s powerful force even disturbed coasts of New Zealand’s islands halfway around the globe.

We get by with a little help from our friends.

The James Webb Space Telescope recently teamed up with two other space observatories to produce dazzling new images of the cosmos. By working together, these telescopes can provide a more complete portrait of the universe.

The Chandra X-ray Observatory added X-ray data to some of Webb’s first images to reveal previously hidden aspects. The X-rays pinpointed exploded stars, a shock wave and superheated gas, all highlighted in glowing pinks, purples and blues.

Additionally, astronomers combined Webb and Hubble data to showcase a pair of galaxies about 700 million light-years away from Earth. Webb scientists also spied a celestial surprise, in the form of a distant galaxy, within the image.

Composting your produce scraps can be great for the environment, but there’s an art to this environmentally friendly practice.

Food waste creates harmful greenhouse gases inside a landfill — and little to none of it is composted. Composting means mixing food and yard waste with nitrogen, carbon, water and air to help scraps decompose and turn into fertile soil that your garden will love.

A compost pile that stinks isn’t getting enough oxygen and is emitting methane. To prevent the formation of this harmful gas, and the smell, turn your compost pile every two to five weeks.

Swedish geneticist Svante Pääbo won the Nobel Prize for medicine this week for his pioneering use of ancient DNA to answer questions about human evolution.

In 2010, Pääbo sequenced the first Neanderthal genome and discovered that Homo sapiens interbred with them. Pääbo was also able to extract DNA from fossil fragments, which revealed Denisovans, a new kind of extinct human.

His work has allowed researchers to compare human genetics with the DNA of Neanderthals and Denisovans.

Meanwhile, the Nobel Prize for chemistry was awarded to scientists who discovered how to snap molecules together, and the Nobel Prize for physics went to quantum physicists for unlocking the eerie behavior of particles.

Check out these new finds:

— Archaeologists have uncovered the pieces of a nearly 2,000-year-old classical statue depicting the mythical hero Hercules in northeastern Greece.

— The Pacific Ocean is shrinking and making way for a new supercontinent, called Amasia, that will likely form in about 200 million to 300 million years.

— A new image from a telescope in Chile may look like a comet, but it’s actually an incredibly long debris trail created when the DART spacecraft slammed into an asteroid last month.

If you love space and exploring the cosmos, there is no shortage of wonder right now.

Scientists identified mysterious diamonds that likely originated from a dwarf planet that once existed in our solar system – until it collided with a large asteroid 4.5 billion years ago.

The rare space diamonds aren’t the only find mesmerizing researchers. A “breathtaking” image captured by the James Webb Space Telescope is revealing the secrets of star birth in the Orion Nebula. Expect to see more unprecedented Webb images in the coming weeks.

Meanwhile, the Artemis I mission has a new launch date scheduled for September 27, with a 70-minute window that opens at 11:37 a.m. ET.

And on Mars, inspiring discoveries are afoot as the Perseverance rover investigates an intriguing site.

The Perseverance rover has made its most exciting find on the red planet to date.

Perseverance has finally collected samples from the site of an ancient river delta, which is full of rock layers that serve as a geological record of the Martian past. Some of the rocks include the highest concentration of organic matter found by the rover to date, according to NASA scientists.

Among the organic matter are minerals that correlate with sulfates, which could preserve evidence of once potentially habitable sites on Mars and the microbial life that may have existed there.

New photos show the promising rocks amid the delta’s alien landscape. These important samples could answer the ultimate cosmic question: Are we alone in the universe?

Modern humans and Neanderthals lived in tandem until our ancient relatives went extinct about 40,000 years ago. Now, researchers think they may have pinpointed something that gave Homo sapiens a cognitive edge over the Stone Age hominins.

Scientists discovered a genetic mutation that may have allowed neurons to form faster in the modern human brain.

“We’ve identified a gene that contributes to making us human,” said study author Wieland Huttner, professor and director emeritus at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden, Germany.

But some experts think more research is needed to ascertain the gene’s true impact.

What’s good for the goose is good for the gander – and these golden geese have provided some pretty significant benefits.

Three teams of scientists won the 2022 Golden Goose Awards, prizes organized by the American Association for the Advancement of Science, for pioneering breakthroughs.

One of those includes the Foldscope, a microscope made from paper that costs $1.75 to make. Stanford University bioengineer Manu Prakash came up with the idea on a research trip in the Thai jungle more than a decade ago.

The scientific instrument has traveled around the world, and researchers have even used it to identify a new type of cyanobacteria.

Mark your calendars: A NASA spacecraft will intentionally crash into a tiny asteroid on September 26.

The Double Asteroid Redirection Test spacecraft, or DART, launched in November and is on its way to a rendezvous with Dimorphos, a small moon orbiting an asteroid called Didymos.

The mission will nudge the asteroid, which poses no threat to Earth, to change its speed and path in a first-of-its-kind test of kinetic impact. If DART is successful, the mission could demonstrate future ways to protect Earth from space debris.

The spacecraft recently got its first glimpse of Didymos from about 20 million miles (32.2 million kilometers) away. On the day of the encounter, we’ll see Dimorphos for the first time before DART collides with the space rock.

The Xerces blue butterfly, Floreana giant tortoise and Tasmanian tiger are just some of the species that the world has lost due to human-driven threats.

Environmental and travel photographer Marc Schlossman has spent 15 years documenting extinct and endangered animal specimens in Chicago’s Field Museum collection for his new book, “Extinction: Our Fragile Relationship With Life on Earth.”

Schlossman provides a glimmer of hope at a time when biodiversity loss is accelerating. Of the 82 species photographed for the book, 23 are extinct, he said.

Thanks to conservation efforts, the rest have been brought back from the brink of disappearing or – as in the case of the New Zealand kākāpo – can recover with “robust” conservation work.

Take a closer look:

– One of Saturn’s moons grazed the gas giant 160 million years ago and smashed apart – and this chaotic encounter could explain the origins of the planet’s signature rings.

– Food DNA from 6,000-year-old pottery found on the Isle of Lewis reveals that ancient Scots enjoyed a breakfast that may sound familiar to us.

– Spectators spied an unusually slow-moving fireball in the night sky over Scotland. The mystery object could be a space rock or space debris.
