Creature named Kermit the Frog offers clues on amphibian evolution

  • Scientists described the fossilized skull of a creature called Kermitops gratus that lived in what is now Texas about 270 million years ago
  • Amphibians are one of the four groups of living terrestrial vertebrates, along with reptiles, birds and mammals

WASHINGTON: There definitely were no muppets during the Permian Period, but there was a Kermit — or at least a forerunner of modern amphibians that has been named after the celebrity frog.

Scientists on Thursday described the fossilized skull of a creature called Kermitops gratus that lived in what is now Texas about 270 million years ago. It belongs to a lineage believed to have given rise to the three living branches of amphibians — frogs, salamanders and limbless caecilians.
While only the skull — measuring around 1.2 inches (3 cm) long — was discovered, the researchers think Kermitops had a stoutly built salamander-like body roughly 6-7 inches (15-18 cm) long, though salamanders would not evolve for another roughly 100 million years.
Amphibians are one of the four groups of living terrestrial vertebrates, along with reptiles, birds and mammals. The unique features of the Kermitops skull — a blend of archaic and more advanced features — are providing insight into amphibian evolution.
“Kermitops helps us understand the early history of amphibians by revealing there isn’t a clear trend of step by step becoming more like the modern amphibian,” said Calvin So, a George Washington University paleontology doctoral student and lead author of the study published in the Zoological Journal of the Linnean Society.

The fossil was collected in 1984 near Lake Kemp in Texas and kept in the expansive collection of the Smithsonian Institution’s National Museum of Natural History in Washington, but was not thoroughly studied until recently.
Kermitops had a rounded snout, not unlike frogs and salamanders. Preserved in its eye sockets were palpebral bones — or eyelid bones — a feature absent in today’s amphibians. Its skull is constructed of roof-like bones, in contrast to the thin and strut-like bones of modern amphibians.
“The length of the skull in front of the eyes is longer than the length of the skull behind the eyes, which differs from the other fossil amphibians living at the same time. We think this might have allowed Kermitops to snap its jaws closed faster, enabling capture of fast insect prey,” So said.
The fossil record of early amphibians and their forerunners is spotty, making it difficult to figure out the origins of modern amphibians.
“Kermitops, with its unique anatomy, really exemplifies the importance of continuing to add new fossil data to understanding this evolutionary problem,” said National Museum of Natural History paleontologist and study co-author Arjan Mann.
Kermit the Frog was created by the late American puppeteer Jim Henson in 1955, and a Kermit puppet made in the 1970s is in the collection of the Smithsonian’s National Museum of American History as an important cultural object.
Kermitops means “Kermit face,” a nod to the muppet’s humorous look.
“We thought that the eyelid bones gave the fossil a bug-eyed look, and combined with a lopsided smile produced by slight crushing during the preservation of the fossil, we really thought it looked like Kermit the Frog,” So said.
Kermitops belonged to a group called temnospondyls that arose a few tens of millions of years after the first land vertebrates evolved from fish ancestors. The biggest temnospondyls superficially resembled crocodiles, including two that each were around 20 feet (6 meters) in length, Prionosuchus and Mastodonsaurus.
Temnospondyls are considered the progenitor lineage of modern amphibians, Mann said.
Kermitops existed about 20 million years before the worst mass extinction in Earth’s history and about 40 million years before the first dinosaurs. It lived alongside other members of the amphibian lineage as well as the impressive sail-backed Dimetrodon, a predator related to the mammalian lineage.
The environment in which Kermitops lived appears to have alternated between warm and humid seasons and hot and arid seasons.
“This environment would be similar to modern-day monsoons that take place in the Southwest US and Southeast Asia,” So said.


Meaty issue: German political party calls for €4.90 price cap on doner kebabs

Meaty issue: German political party calls for €4.90 price cap on doner kebabs

  • Die Linke appeals to government as price of national favorite hits €10 in some cities
  • Scheme would cost taxpayer about €4bn

LONDON: German political party Die Linke has urged the government to cap the price of a much loved food item — the doner kebab.

The party has proposed providing daily vouchers to households that would limit prices to €4.90 ($5.28) and €2.90 for young people under an initiative known as Donerpreisbremse.

The scheme is projected to cost the government about €4 billion.

Introduced after the Second World War by Turkish immigrants who adapted the dish to suit local tastes, the doner kebab is a national favorite in Germany, with an estimated 1.3 billion consumed annually. But their soaring price has become a hot-button political issue.

Die Linke said the cost of a doner kebab had reached €10 in some cities, from €4 just two years ago.

“For young people right now it is an issue as important as where they will move when they leave home,” said Hanna Steinmuller, a lawmaker with the Greens party.

“I know it’s not an everyday issue for many people here … but I think as voter representatives we are obliged to highlight these different perspectives.”

German Chancellor Olaf Scholz was famously confronted by a voter last year who demanded he “speak with Putin … I’m paying €8 for a doner.”

With public pressure mounting, Scholz recently acknowledged on social media that “everywhere I go, mostly by young people, I get asked if there should be a price cap for doner kebabs.”

Despite the appeals, the chancellor rejected the proposal, citing the impracticality of price controls in a free market economy.

Despite its humble origins as a street food, the doner kebab has become an unexpected point of political focus.

Last month, German President Frank-Walter Steinmeier sparked controversy when on a visit to Turkiye he gifted 60 kg of kebab meat from Berlin to Istanbul in what some called a clumsy attempt to symbolize the strong cultural ties between the two nations.


A 98-year-old in Ukraine walked miles to safety from Russians, with slippers and a cane

A 98-year-old in Ukraine walked miles to safety from Russians, with slippers and a cane

  • Describing her journey, the nonagenarian said she had fallen twice and was forced to stop to rest at some points, even sleeping along the way before waking up and continuing her journey

KYIV, Ukraine: A 98-year-old woman in Ukraine who escaped Russian-occupied territory by walking almost 10 kilometers (6 miles) alone, wearing a pair of slippers and supported by a cane has been reunited with her family days after they were separated while fleeing to safety.
Lidia Stepanivna Lomikovska and her family decided to leave the frontline town of Ocheretyne, in the eastern Donetsk region, last week after Russian troops entered it and fighting intensified.
Russians have been advancing in the area, pounding Kyiv’s depleted, ammunition-deprived forces with artillery, drones and bombs.
“I woke up surrounded by shooting all around — so scary,” Lomikovska said in a video interview posted by the National Police of Donetsk region.
In the chaos of the departure, Lomikovska became separated from her son and two daughters-in-law, including one, Olha Lomikovska, injured by shrapnel days earlier. The younger family members took to back routes, but Lydia wanted to stay on the main road.
With a cane in one hand and steadying herself using a splintered piece of wood in the other, the pensioner walked all day without food and water to reach Ukrainian lines.
Describing her journey, the nonagenarian said she had fallen twice and was forced to stop to rest at some points, even sleeping along the way before waking up and continuing her journey.
“Once I lost balance and fell into weeds. I fell asleep … a little, and continued walking. And then, for the second time, again, I fell. But then I got up and thought to myself: “I need to keep walking, bit by bit,’” Lomikovska said.
Pavlo Diachenko, acting spokesman for the National Police of Ukraine in the Donetsk region, said Lomikovska was saved when Ukrainian soldiers spotted her walking along the road in the evening. They handed her over to the “White Angels,” a police group that evacuates citizens living on the front line, who then took her to a shelter for evacuees and contacted her relatives.
“I survived that war,’ she said referring to World War II. “I had to go through this war too, and in the end, I am left with nothing.
“That war wasn’t like this one. I saw that war. Not a single house burned down. But now – everything is on fire,” she said to her rescuer.
In the latest twist to the story, the chief executive of one of Ukraine’s largest banks announced on his Telegram channel Tuesday that the bank would purchase a house for the pensioner.
“Monobank will buy Lydia Stepanivna a house and she will surely live in it until the moment when this abomination disappears from our land,” Oleh Horokhovskyi said.

Amazon Purr-rime: Cat accidentally shipped to online retailer

  • Galena was found safe by a warehouse worker at an Amazon center after vanishing from her home in Utah

LOS ANGELES: A curious cat that sneaked into an open box was shipped across the United States to an Amazon warehouse after its unknowing owners sealed it inside.
Carrie Clark’s pet, Galena, vanished from her Utah home on April 10, sparking a furious search that involved plastering “missing” posters around the neighborhood.
But a week later, a vet hundreds of miles (kilometers) away in Los Angeles got in touch to say the cat had been discovered in a box — alongside several pairs of boots — by a warehouse worker at an Amazon center.
“I ran to tell my husband that Galena was found and we broke down upon realizing that she must have jumped into an oversized box that we shipped out the previous Wednesday,” Clark told KSL TV in Salt Lake City.
“The box was a ‘try before you buy,’ and filled with steel-toed work boots.”
Clark and her husband jetted to Los Angeles, where they discovered Amazon employee Brandy Hunter had rescued Galena — a little hungry and thirsty after six days in a cardboard box, but otherwise unharmed.
“I could tell she belonged to someone by the way she was behaving,” said Hunter, according to Amazon.
“I took her home that night and went to the vet the next day to have her checked for a microchip, and the rest is history.”

What did people eat before agriculture? New study offers insight

  • Analysis of forms — or isotopes — of elements including carbon, nitrogen, zinc, sulfur and strontium in these remains indicated the type and amount of plants and meat they ate

WASHINGTON: The advent of agriculture roughly 11,500 years ago in the Middle East was a milestone for humankind — a revolution in diet and lifestyle that moved beyond the way hunter-gatherers had existed since Homo sapiens arose more than 300,000 years ago in Africa.
While the scarcity of well-preserved human remains from the period preceding this turning point has made the diet of pre-agricultural people a bit of a mystery, new research is now providing insight into this question. Scientists reconstructed the dietary practices of one such culture from North Africa, surprisingly documenting a heavily plant-based diet.
The researchers examined chemical signatures in bones and teeth from the remains of seven people, as well as various isolated teeth, from about 15,000 years ago found in a cave outside the village of Taforalt in northeastern Morocco. The people were part of what is called the Iberomaurusian culture.
Analysis of forms — or isotopes — of elements including carbon, nitrogen, zinc, sulfur and strontium in these remains indicated the type and amount of plants and meat they ate. Found at the site were remains from different edible wild plants including sweet acorns, pine nuts, pistachio, oats and legumes called pulses. The main prey, based on bones discovered at the cave, was a species called Barbary sheep.
“The prevailing notion has been that hunter-gatherers’ diets were primarily composed of animal proteins. However, the evidence from Taforalt demonstrates that plants constituted a big part of the hunter-gatherers’ menu,” said Zineb Moubtahij, a doctoral student in archaeology at the Max Planck Institute for Evolutionary Anthropology in Germany and lead author of the study published on Monday in the journal Nature Ecology & Evolution.
“It is important as it suggests that possibly several populations in the world already started to include substantial amount of plants in their diet” in the period before agriculture was developed, added archeogeochemist and study co-author Klervia Jaouen of the French research agency CNRS.
The Iberomaurusians were hunter-gatherers who inhabited parts of Morocco and Libya from around 25,000 to 11,000 years ago. Evidence indicates the cave served as a living space and burial site.
These people used the cave for significant portions of each year, suggesting a lifestyle more sedentary than simply roaming the landscape searching for resources, the researchers said. They exploited wild plants that ripened at different seasons of the year, while their dental cavities illustrated a reliance on starchy botanical species.
Edible plants may have been stored by the hunter-gatherers year-round to guard against seasonal shortages of prey and ensure a regular food supply, the researchers said.
These people ate only wild plants, the researchers found. The Iberomaurusians never developed agriculture, which came relatively late to North Africa.
“Interestingly, our findings showed minimal evidence of seafood or freshwater food consumption among these ancient groups. Additionally, it seems that these humans may have introduced wild plants into the diets of their infants at an earlier stage than previously believed,” Moubtahij said.
“Specifically, we focused on the transition from breastfeeding to solid foods in infants. Breast milk has a unique isotopic signature, distinct from the isotopic composition of solid foods typically consumed by adults.”
Two infants were among the seven people whose remains were studied. By comparing the chemical composition of an infant’s tooth, formed during the breastfeeding period, with the composition of bone tissue, which reflects the diet shortly before death, the researchers discerned changes in the baby’s diet over time. The evidence indicated the introduction of solid foods at around the age of 12 months, with babies weaned earlier than expected for a pre-agricultural society.
North Africa is a key region for studying Homo sapiens evolution and dispersal out of Africa.
“Understanding why some hunter-gatherer groups transitioned to agriculture while others did not can provide valuable insights into the drivers of agricultural innovation and the factors that influenced human societies’ decisions to adopt new subsistence strategies,” Moubtahij said.

Palestinian prisoner in Israel wins top fiction prize

  • The mask in the novel’s title refers to the blue identity card that Nur, an archaeologist living in a refugee camp in Ramallah, finds in the pocket of an old coat belonging to an Israeli

ABU DHABI: Palestinian writer Basim Khandaqji, jailed 20 years ago in Israel, won a prestigious prize for Arabic fiction on Sunday for his novel “A Mask, the Color of the Sky.”
The award of the 2024 International Prize for Arabic Fiction was announced at a ceremony in Abu Dhabi.
The prize was accepted on Khandaqji’s behalf by Rana Idriss, owner of Dar Al-Adab, the book’s Lebanon-based publisher.
Khandaqji was born in the Israeli-occupied West Bank city of Nablus in 1983, and wrote short stories until his arrest in 2004 at the age of 21.
He was convicted and jailed on charges relating to a deadly bombing in Tel Aviv, and completed his university education from inside jail via the Internet.
The mask in the novel’s title refers to the blue identity card that Nur, an archaeologist living in a refugee camp in Ramallah, finds in the pocket of an old coat belonging to an Israeli.
Khandaqji’s book was chosen from 133 works submitted to the competition.
Nabil Suleiman, who chaired the jury, said the novel “dissects a complex, bitter reality of family fragmentation, displacement, genocide, and racism.”
Since being jailed Khandaqji has written poetry collections including “Rituals of the First Time” and “The Breath of a Nocturnal Poem.”
He has also written three earlier novels.
