WASHINGTON: The horses that galloped the earth just a thousand years ago probably looked very different from their modern descendants, researchers said Thursday after compiling the most complete genetic history of any non-human species.
But the biggest surprise of the vast study, which involved an international team of 121 scientists and was published Thursday in the journal Cell, was the staggering loss of genetic diversity in the past 200 to 300 years that accompanied modern breeding practices.
The horse was one of the last animals that was domesticated by humans, long after dogs, cattle and pigs.
But around 5,500 years ago, people began to ride, milk and lock horses in pens — and things would never be the same between the two species.
“The horse has had a profound effect on human history,” said Ludovic Orlando, a research director with CNRS and the University of Toulouse, who coordinated the study.
Thanks to the horse, “we were able to go faster, further, and to conquer new territories. We went to war differently. We were able to plow fields and do agriculture,” he said.
“The horse of Alexander the Great was so remarkable that we know his name, Bucephalus.”
But scientists still don’t know the answer to a key question: what was the ancestor of the current domestic horse?
To this end, the team analyzed the genomes of 278 specimens (mostly horses but also donkeys and mules discovered inadvertently), mostly from the past 5,000 years, across Europe and Asia.
“This is the largest register of ancient genomes ever collected for a non-human species,” said Orlando.
Ancient genetics research saw a major technological leap in 2010 that allowed the team, working in a Toulouse laboratory, to extract and analyze DNA from bones that was not accessible before.
This led to a number of surprising discoveries: for one, an ancient line of horses were present in Iberia until at least 4,000 years ago — before mysteriously disappearing completely.
On the other end of the Eurasian landmass, another lineage of horses roaming Siberia also completely disappeared around the third millennium BCE.
“They are a sort of horse equivalent of what Neanderthals are to modern humans,” Orlando said.
Today there remain but two lineages: the domestic horse and Przewalski’s horse, also called the Mongolian wild horse.
They most likely originated in Central Asia, but this is only a hypothesis: to date, no genetic ancestor has been found.
Scientists say they are struck by the speed with which the genetic diversity of horses collapsed in the last two to three centuries, after remaining constant for the previous 4,000 years of domestication.
The 16th and 17th centuries saw the emergence of the concept of “pure” breeds.
“All the current breeds, from the Shetland pony to the Thoroughbred, were made then,” said Orlando, with traits such as speed over short distances probably favored.
Another major shift occurred between the 7th and 9th centuries, during the Arab-Muslim expansion. The invaders brought with them an oriental horse, descended from the Persian empire of the Sassanids.
A more elegant animal with a finer silhouette, this horse mixed with those that were predominant in Europe at the time, while their ancestors, those mounted by the Romans and Gauls, are today confined to two regions: Iceland and the British Isles, where they were taken by the Vikings.
“What we picture as a horse today and what we picture as a horse from a thousand years ago or two thousand years ago was likely actually very different,” said Orlando — who says his next goal, with the more than 30 other universities involved in the project, is to find out which human culture first domesticated our equine friends.
“Horse domestication is central to human history, and in 2019, we still don’t understand where it started. That’s mind-blowing.”

Swedish club not skirting around shorts issue as they back Irish camogie players
- The Irish sport hit the headlines this week for all the wrong reasons with players
- Camogie is the female version of hurling, a ball sport played with wooden sticks
STOCKHOLM: Camogie players in Sweden have turned the clock back by wearing a kit from a bygone age in a show of solidarity with colleagues in Ireland currently protesting for the right to wear shorts.
The Irish sport hit the headlines this week for all the wrong reasons with players, tired of a rule outlawing the wearing of shorts, ramping up protests, ultimately leading to the late postponement of Saturday’s Munster final.
Camogie is the female version of hurling, a ball sport played with wooden sticks, often likened to a mix between lacrosse and hockey, with a little rugby thrown in because of its physicality.
Wherever you go in the world, from Uganda to Vietnam, you are likely to find people playing Ireland’s national sports. Sweden is no different, and Irishwoman Michelle Cotter set up the hurling and camogie teams at Stockholm Gaels.
“The goal was to do something over here to show the players back home that their impact is reaching much further than the island of Ireland,” Cotter told Reuters.
The Camogie Association of Ireland’s rules state that playing gear must include skirt, skort or divided skirt, but a recent survey showed that 83 percent of players want the choice to include shorts.
The Stockholm club, which includes not only Irish players and local Swedes but women from Australia, Austria, the US, Britain, France and Spain, took things back to even before the days of skorts, when players wore skirts down to their ankles.
The first set of camogie rules, drawn up in 1903, stated skirts should be worn no more than six inches from the ground and, while things have improved, two motions to introduce shorts were defeated at last year’s Camogie Association congress.
“Given none of us even own skorts, we togged out for training in skirts and dresses,” Cotter, who also coaches and plays on the team, said. “It felt every bit as ridiculous as it looked.”
There is still hope for change following all the media attention and controversy of the past week, after the association agreed to hold a special congress on May 22 to vote again on a motion to allow the wearing of shorts.
Liam and Olivia dominate — again — with top baby names in the US for a sixth year in a row
- ‘A trend we’re tracking is that Americans are more likely to choose heritage choices’
WASHINGTON: Liam and Olivia dominate. Still.
The two names have, for a sixth year together, topped the list of names for babies born in the US in 2024.
The Social Security Administration annually tracks the names given to girls and boys in each state, with names dating back to 1880. In time for Mother’s Day, the agency on Friday released the most popular names from applications for Social Security cards.
Liam has reigned for eight years in a row for boys, while Olivia has topped the girls’ list for six. Also, for the sixth consecutive year, Emma took the second slot for girls, and Noah for boys.
The girls’ name Luna slipped out of the Top 10 and was replaced by Sofia, which enters at number 10 for the first time.
After Liam, the most common names for boys are, in order: Noah, Oliver, Theodore, James, Henry, Mateo, Elijah, Lucas and William.
After Olivia, the most common names for girls are Emma, Amelia, Charlotte, Mia, Sophia, Isabella, Evelyn, Ava and Sofia.
Sophie Kihm, editor-in-chief of nameberry, a baby naming website, said the latest data showcases how American parents are increasingly choosing names that have cross-cultural appeal. Kihm’s first name shows up in two variations on the annual list.
“A trend we’re tracking is that Americans are more likely to choose heritage choices,” Kihm said, including names that work “no matter where you are in the world.”
”More families in the US come from mixed cultural backgrounds and I hear parents commonly request that they want their child to travel and have a relatively easy to understand name.”
The Social Security Administration’s latest data show that 3.61 million babies were born in the US in 2024. That’s a slight increase from last year’s 3.59 million babies, representing an overall increase in the American birthrate.
Social media stars and popular television shows are having some impact on the rising popularity of certain names, Social Security says.
Among those rising in popularity for girls: Ailany, a Hawaiian name that means “chief,” topped the list. The boys’ name Truce, an Old English name meaning “peace,” rose 11,118 spots from last year’s position to rank 991.
The complete, searchable list of baby names is on the Social Security website.
Sweden’s new national security adviser quits over dating site images
- Thyberg said that he had failed to disclose the existence of the images
- “I should have informed about this, but I did not,” he said
OSLO: Sweden’s new national security adviser abruptly resigned on Friday, just one day after his appointment, amid criticism from the prime minister that he failed to disclose information regarding images published years ago on a dating website.
Tobias Thyberg, a foreign service veteran who in previous roles served as ambassador to both Ukraine and Afghanistan, had omitted the information during security background checks, the government said.
The resignation comes just months after Thyberg’s predecessor in the high-profile job stepped down and was charged with negligent handling of classified information.
Thyberg did not immediately respond to Reuters requests for comment on Friday.
But in a statement to daily Dagens Nyheter, Thyberg said that he had failed to disclose the existence of the images.
“These are old pictures from an account I previously had on the dating site Grindr. I should have informed about this, but I did not,” he said, according to DN.
Reuters could not independently verify information about the content of the images.
Background checks for sensitive government jobs typically require the disclosure of any information that could potentially make someone vulnerable to blackmail.
Prime Minister Ulf Kristersson said the information should have come to light a long time ago.
“It is a systemic failure that this kind of information has not been brought forward,” Kristersson told reporters on the sidelines of a conference in Norway.
Thyberg had been due to travel to Oslo on Friday with the prime minister for a meeting of northern European leaders, but the adviser’s participation was canceled.
Two men found guilty of chopping down iconic UK tree
- The tree at Sycamore Gap had stood for nearly 200 years next to Hadrian’s Wall, a UNESCO World Heritage site in northern England
- The tree was so striking it featured in the 1991 Hollywood film “Robin Hood: Prince of Thieves“
LONDON: An English court found two men guilty on Friday of the “deliberate and mindless” felling of one of the UK’s most iconic trees, an incident that sparked national outrage.
A jury at Newcastle Crown Court found former friends Daniel Graham, 39, and Adam Carruthers, 32, guilty of criminal damage for the 2023 felling of the tree at Sycamore Gap.
It had stood for nearly 200 years next to Hadrian’s Wall, a UNESCO World Heritage site in northern England. The tree was so striking it featured in the 1991 Hollywood film “Robin Hood: Prince of Thieves.”
They were convicted after around five hours of deliberation on two counts of criminal damage: to the sycamore and to the Roman wall, which was damaged when the tree fell on it.
Reacting to the verdict, the National Trust conservation body said the “needless felling” of the tree had “shocked people around the country and overseas, demonstrating the powerful connection between people and our natural heritage.
“It was felt particularly deeply here in the north east of England where the tree was an emblem of the region and the backdrop to many personal memories,” said a spokesperson.
Prosecutors had told the court that the two men used a chainsaw to cut down the tree. It was, they said, “an act of deliberate and mindless criminal damage,” which they filmed on Graham’s phone and shared with others.
Speaking after the conviction, Northumbria Police’s Kevin Waring said: “We often hear references made to mindless acts of vandalism, but that term has never been more relevant than today.
“At no point have the two men given an explanation for why they targeted the tree — and there never could be a justifiable one,” he added.
Graham has “been in custody for his own protection after an episode in December,” his lawyer Chris Knox told court on Friday.
The pair drove to the site near Hexham in Graham’s Range Rover and felled the tree on the night of September 27, 2023, slicing through the trunk in “a matter of minutes,” said prosecutor Richard Wright.
“Having completed their moronic mission, the pair got back into the Range Rover and traveled back toward Carlisle” where they lived, he added.
A video of the act recovered from Graham’s phone was shared by the two men with “the unmistakable sound of a chainsaw, and a tree falling,” said Wright.
The next day, in a voice message from Graham to Carruthers, Graham said “it’s gone viral. It is worldwide. It will be on ITV news tonight,” he added.
“They are loving it, they’re revelling in it. This is the reaction of the people that did it. They still think it’s funny, or clever, or big,” said the prosecutor.
Gale Gilchrist, from the Crown Prosecution Service North, said that “in just under three minutes, Graham and Carruthers ended its (the tree’s) historic legacy in a deliberate and mindless act of destruction.
“We hope our community can take some measure of comfort in seeing those responsible convicted today,” she added.
The pair were jointly charged with causing £622,191 ($832, 821) of criminal damage to the tree and £1,144 of damage to Hadrian’s Wall, an ancient Roman fortification stretching from northwest to northeast England.
The two men have been remanded in custody — Carruthers for his own protection. They will be sentenced on July 15.
The sycamore was a symbol of northeast England and a key attraction photographed by millions of visitors over the years, winning the Woodland Trust’s Tree of the Year in 2016.
Efforts are under way to see if it can be regrown from its stump or seeds.
The National Trust, which owns the wall and the tree, said it has grown 49 saplings from the sycamore’s seeds, which will be planted this winter at sites across the UK.
Rare New Zealand snail is filmed for the first time laying an egg from its neck
- The habits of the threatened Powelliphanta augusta snail were once shrouded in mystery
- The video was taken at a facility on the South Island’s West Coast
WELLINGTON: The strange reproductive habits of a large, carnivorous New Zealand snail were once shrouded in mystery. Now footage of the snail laying an egg from its neck has been captured for the first time, the country’s conservation agency said Wednesday.
What looks like a tiny hen’s egg is seen emerging from an opening below the head of the Powelliphanta augusta snail, a threatened species endemic to New Zealand.
The video was taken at a facility on the South Island’s West Coast, where conservation rangers attempting to save the species from extinction have cared for a population of the snails in chilled containers for nearly two decades.
The conditions in the containers mimic the alpine weather in their only former habitat — a remote mountain they were named for, on the West Coast of the South Island, that has been engulfed by mining.
Observing their habits
Lisa Flanagan from the Department of Conservation, who has worked with the creatures for 12 years, said the species still holds surprises.
“It’s remarkable that in all the time we’ve spent caring for the snails, this is the first time we’ve seen one lay an egg,” she said in a statement.
Like other snails, Powelliphanta augusta are hermaphrodites, which explains how the creatures can reproduce when encased in a hard shell. The invertebrate uses a genital pore on the right side of its body, just below the head, to simultaneously exchange sperm with another snail, which is stored until each creates an egg.
A long but slow reproductive life
Each snail takes eight years to reach sexual maturity, after which it lays about five eggs a year. The egg can take more than a year to hatch.
“Some of our captive snails are between 25 and 30 years old,” said Flanagan. “They’re polar opposites to the pest garden snail we introduced to New Zealand, which is like a weed, with thousands of offspring each year and a short life.”
The dozens of species and subspecies of Powelliphanta snails are only found in New Zealand, mostly in rugged forest and grassland settings where they are threatened by habitat loss.
They are carnivores that slurp up earthworms like noodles, and are some of the world’s largest snails , with oversized, distinctive shells in a range of rich earth colors and swirling patterns.
A political storm
The Powelliphanta augusta was the center of public uproar and legal proceedings in the early 2000s, when an energy company’s plans to mine for coal threatened to destroy the snails’ habitat.
Some 4,000 were removed from the site and relocated, while 2,000 more were housed in chilled storage in the West Coast town of Hokitika to ensure the preservation of the species, which is slow to breed and doesn’t adapt well to new habitats.
In 2011, some 800 of the snails accidentally died in a Department of Conservation refrigerator with faulty temperature control.
But the species’ slow survival continues: In March this year, there were nearly 1,900 snails and nearly 2,200 eggs in captivity, the conservation agency said.
