By analysing mammoth remains found in Condover, Shropshire, scientists concluded that the animals were probably wiped out by rapidly changing climate at the end of the last ice age rather than hunted to extinction by humans."Mammoths are conventionally believed to have become extinct in north-western Europe about 21,000 years ago during the main ice advance, known as the last glacial maximum," said Adrian Lister, of the Natural History Museum, in London, who led the study. "Our new radiocarbon dating of the Condover mammoths changes that by showing that mammoths returned to Britain and survived until around 14,000 years ago."The last ice age occurred between 75,000 and 12,000 years ago. During that time, the Earth's climate changed regularly with relatively colder and warmer periods.A particularly cold period started 21,000 years ago with ice sheets expanding all over Britain. At this stage, the mammoths and many other mammals disappeared from this part of Europe.Lister's research, published in tomorrow's issue of the , suggests that the animals returned to Britain as the region warmed up again."Plant growth had started again and there was rich grassland and that's exactly what the mammoths liked," said Lister. "The mammoths had been hiding out in Siberia in relatively low numbers during the glaciation maximum. They came back into Europe for a few thousand years on this rich grassland until the forests arrived and it got really warm, and that's when they died out completely."Scientists have been arguing for years over the cause of the mammoths' extinction. One idea is that humans hunted them out, another is that climate change made life too difficult for them."We think our research shows that climatic change, particularly working through its effect on the vegetation, was largely responsible for the extinction," said Lister. "It was certainly responsible for squeezing the range of this species right down."Humans might have had a hand in killing off the last remaining populations but without climate change cutting the creatures' numbers in the first place, the species, consisting of millions of individuals, would not have been wiped out just by people.The Condover mammoth remains, of a single adult male and at least four calves, were found in 1986 but the radiocarbon dating used then to work out their age was later proved inaccurate.To date bones, a protein called collagen is first extracted, but this material can often get mixed up with organic matter from the environment where the remains are found. "If the thing's been buried in the ground and it rains and organic dissolved matter from the plants above is filtering down and might get absorbed by the bone, then the date could end up being too late," said Lister.His research took advantage of improved radiocarbon dating and biological sample filtering. Calculations on the age of the mammoth bones were also based on an analysis of how they had decayed, a geological assessment of the surrounding rocks, and fossilised insects found at the site.Explore more on these topicsReuse this contentMost viewedMost viewedUSUS politicsWorldClimate crisisMiddle EastUkraineSoccerBusinessEnvironmentTechScienceNewslettersWellnessOriginal reporting and incisive analysis, direct from the Guardian every morningAbout usHelpComplaints & correctionsSecureDropWork for us Privacy policyCookie policyTerms & conditionsContact usAll topicsAll writersDigital newspaper archiveTax strategyFacebookYouTubeInstagramLinkedInNewslettersAdvertise with usGuardian LabsSearch jobsTips© 2025 Guardian News & Media Limited or its affiliated companies.

There are now only two female northern white rhinos left, Najin and Fatu, both living at Ol Pejeta Conservancy in Kenya heavily protected by armed guards. However, some exciting advancements have been made with scientists and conservationists successfully creating 24 northern white rhino embryos to use for in vitro fertilization., 100,000 years ago, in the context of life on Earth, seems like a short amount of time. numerous other species of human beings in climates that are dramatically different than today, this was , Gigantophis held the title of the world's largest snake for more than a century — until Titanoboa was discovered in the 2000s. Titanoboa cerrejonensis, now considered the largest known snake in history, lived approximately 58 to 60 million years ago during the Paleocene epoch, a period just after the extinction of the dinosaurs., The researchers measured the horns of 80 rhinos, photographed in profile view between 1886 and 2018. The photographs, held by the Rhino Resource Centre – an online repository – included all five species of rhino: white, black, Indian, Javan and Sumatran. Horn length was found to have decreased significantly in all species over the last century., First appearance of hominoid apes in Eurasia (23-16 mya), Africa more uniformly wet, wooded place with lots of rainforests, Alps and Himalayas were first formed, the Tethy's recedes Middle Miocene Monkeys were more abundant than apes, more seasons and open country environments, apes expanded to Eurasia from Spain to China, .
