Ants are among the most familiar insects on Earth today, but their origins remain cloaked in deep evolutionary history. Until now, the oldest known ant specimens came from amber deposits in France and Myanmar, dating to the Cretaceous period around 100 million years ago. But a new discovery—published recently in the journal Current Biology—pushes that timeline back even further. “Our team has discovered a new fossil ant species representing the earliest undisputable geological record of ants,” said lead author Anderson Lepeco in a recent statement. “What makes this discovery particularly interesting is that it belongs to the extinct ‘hell ant,’...

Early humans of Homo juluensis had a large head shape, with measurements notably larger than those of Neanderthals and Homo sapiens. Scientists have announced the discovery of a new human species, Homo juluensis, following extensive research published in Nature Communications. Professor Christopher J. Bae from the University of Hawaii and Xiujie Wu from the Chinese Academy of Sciences led the study, which sheds light on the diversity of ancient human populations in East Asia.

The human ability to walk and run efficiently on two feet arose around 2 million years ago with our Homo erectus ancestors. But our earlier relatives, the australopithecines, were also bipedal around 4 million years ago. Given the long arms and different body proportions of species like Australopithecus afarensis, though, researchers have assumed that australopithecines were less capable of walking on two legs than modern humans. In a study published online Dec. 18 in the journal Current Biology, a team of researchers modeled the skeletal and muscular anatomy of Lucy to determine her maximum running speed, the energetic costs associated...

In 2018, a female Neanderthal was discovered in the Shanidar Cave in Iraqi Kurdistan. Now, archaeologists from The University of Cambridge have unveiled the reconstructed face of the 75,000-year-old woman, based on the assembly of hundreds of individual bone fragments recovered during excavations. “Neanderthals have had a bad press ever since the first ones were found over 150 years ago,” said Professor Graeme Barker from Cambridge’s McDonald Institute for Archaeological Research, who led the excavation at the cave where the woman’s remains were discovered. Neanderthals are believed to have become extinct around 40,000 years ago, and discoveries of their remains...

Tails are useful in many ways, but — unlike these vervet monkeys pictured in Lake Mburo National Park in Uganda — humans' closest primate relatives lost the appendages about 25 million years ago. (Photo credit: imageBROKER/Shutterstock via CNN Newsource) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Humans have many wonderful qualities, but we lack something that’s a common feature among most animals with backbones: a tail. Exactly why that is has been something of a mystery. Tails are useful for balance, propulsion, communication and defense against biting insects. However, humans and our closest primate relatives — the great apes — said farewell to tails about 25...

A team of international scientists have discovered 240-million-year-old fossils from the Triassic period in China that one scientist described as a "long and snake-like, mythical Chinese dragon." The 16-foot-long aquatic reptile, called Dinocephalosaurus orientalis, has 32 separate neck vertebrae – an extremely long neck, according to the National Museums of Scotland, which announced the news on Friday. The new fossil has a snake-like appearance and flippers and was found in the Guizhou Province of southern China. Dinocephalosaurus orientalis was first identified in 2003 when its skull was found, but this more complete fossil discovery has "allowed scientists to depict the...

In 2022, researchers stumbled upon the footprint site near the northern tip of North Africa while examining boulders at a nearby pocket beach. A team of archaeologists have unveiled the discovery of the oldest human footprints ever recorded in North Africa and the southern Mediterranean. The footprints, dating back an astonishing 90,000 years, were found on a beach in Larache, Morocco, by a multinational team led by Moncef Essedrati, a research professor and laboratory director at the French University of Southern Brittany. "Between tides, I said to my team that we should go north to explore another beach," Essedrati told...

Dr Valentina Rossi of University College Cork, Ireland, who led the research team which discovered that a 280-million-year-old lizard fossil is, in part, a forgery. (Image credit: Zixiao Yang) A 280-million-year-old fossil that has baffled researchers for decades has been shown to be, in part, a forgery following new examination of the remnants. The discovery has led the team led by Dr Valentina Rossi of University College Cork, Ireland (UCC) to urge caution in how the fossil is used in future research. Tridentinosaurus antiquus was discovered in the Italian alps in 1931 and was thought to be an important specimen...

A newly described fossil suggests that the ancestor of humans and apes arose in Europe, not in Africa...In the new study, the researchers analyzed a newly identified ape fossil from the 8.7 million-year-old site of Çorakyerler in central Anatolia. They dubbed the species Anadoluvius turkae. "Anadolu" is the modern Turkish word for Anatolia, and "turk" refers to Turkey.The fossil suggests that A. turkae likely weighed about 110 to 130 pounds (50 to 60 kilograms), or about the weight of a large male chimpanzee.Based on the fossils of other animals found alongside it — such as giraffes, warthogs, rhinos, antelope, zebras,...

Prof. Begun said: "Our findings further suggest that hominines [bonobos, chimpanzees, and gorillas] not only evolved in western and central Europe - but spent over five million years evolving there and spreading to the eastern Mediterranean before eventually dispersing into Africa."....This migration, he added, was "probably a consequence of changing environments and diminishing forests."

If the claims are true, the behavior by Homo naledi—a baffling, small-brained member of the human family tree—would pre-date the earliest known burials by at least 100,000 years. An extinct human species that lived hundreds of thousands of years ago may have deliberately buried its dead and carved meaningful symbols deep in a South African cave—advanced behaviors generally deemed unique to Neanderthals and modern Homo sapiens. If confirmed, the burials would be the earliest yet known by at least 100,000 years. The claims, made today in two research papers uploaded to the preprint server bioRxiv, were also announced by paleoanthropologist...

Dinosaur that lived 85 million years ago was size of a bus, but breathed like a bird A huge carnivorous dinosaur that lived about 85 million years ago had a breathing system much like that of today's birds, a new analysis of fossils reveals, reinforcing the evolutionary link between dinos and modern birds.

Around 120 million years ago, four-winged dinosaurs roughly the size of crows called Microraptors stalked the ancient woodlands of what is now China.While researchers have studied several Microraptor specimens, there's still a lot we don't know about these feathered bird-like creatures – including what and how they ate.Now an incredibly rare fossil has revealed the preserved final meal of one individual: and unexpectedly, it was a mammal...The first Microraptor fossil was found in Liaoning, China, in 2000. There are three known species, which lived in the early Cretacious period, and the fossil in question belongs to Microraptor zhaoianus...The Microraptors were...

A blackened, broken leg bone from Earth’s prehistoric past may hold the answer to when early humans diverged from apes and started their own evolutionary path.The fossilized find, first uncovered two decades ago, suggests that early humans regularly walked on two feet some seven million years ago... Since many consider bipedalism the major milestone that put our own lineage on a different evolutionary path than the apes, Sahelanthropus could be the very oldest known hominin—the group consisting of modern humans, extinct human species and all of our immediate ancestors.The species could even be our oldest non-ape ancestor, if its lineage...

Lizard Skull Fossil Closeup One of the Thalassotitan skulls. (University of Bath) The discovery of incredible fossils of a giant marine lizard reveals how this ancient extinct beast would have ruled the sea 66 million years ago. The beast is a newly discovered species of mosasaur, giant marine reptiles that hunted the oceans during the Late Cretaceous. It's called Thalassotitan atrox, and wear on its teeth along with other remains found at its excavation site suggest that this intimidating animal was no gentle giant – but feasted on difficult prey such as sea turtles, plesiosaurs, and other mosasaurs. Other mosasaurs...

A joint Ethiopian-US team of palaeontologists announced on Saturday they had discovered the world's oldest biped skeleton to be unearthed so far, dating it to between 3.8 and four million years old. "This is the world's oldest biped," Bruce Latimer, director of the natural history museum in Cleveland, Ohio, told a news conference in the Ethiopian capital, adding that "it will revolutionise the way we see human evolution".The bones were found three weeks ago in Ethiopia's Afar region, at a site some 60 kilometres from Hadar where Lucy, one of the first hominids, was discovered in 1974. Researchers at the...

An Australian academic who has examined the skeletal remains of a three-foot hominid discovered in an Indonesian cave and nicknamed a "hobbit" disputed Friday a report that they represent a new species of human. Professor Maciej Henneberg, head of anatomy at Adelaide University, said he thought the bones found in 2003 on Indonesia's Flores island were simply those of a normal human stunted by a viral disease, microcephaly -- a conclusion rejected in the earlier report by another team of scientists. That team analyzed the find and said the partial skeleton was evidence of a new, dwarf species of human....

Research on human fossils generally proceeds at a leisurely pace. Those who discover new bones sometimes take years to analyze them, while their colleagues and rivals wait impatiently to get a good look. But that's not the case with the 18,000-year-old "hobbit" skeleton of Indonesia. Ever since the Australian- Indonesian team that discovered the bones made the startling claim that they are the remains of a species of small, archaic human, Homo floresiensis (Nature, 28 October, p. 1055), the bones have been analyzed and reanalyzed at a breathtaking pace. For the past 3 months, however, the studies have been directed...

"Little Foot" one of several well-known fossils found at Sterkfontein caves in South Africa's Cradle of Humankind. The fossils of our earliest ancestors found in South Africa are a million years older than previously thought, meaning they walked the Earth around the same time as their East African relatives like the famous "Lucy", according to new research. The Sterkfontein caves at the Cradle of Humankind world heritage site southwest of Johannesburg have yielded more Australopithecus fossils than any other site in the world. Among them was "Mrs Ples", the most complete skull of an Australopithecus africanus found in South...
