A new study suggests that rising and falling sea levels played a key role in the distribution of species across the Galapagos by repeatedly connecting and then isolating the 16 equatorial islands.
Archaeologists and Native Americans are clashing over Indian remains and artifacts that were...
Scientists have long been trying to understand how the Andes and other broad, high-elevation...
Asteroid and comet impacts can cause widespread ecological havoc, killing off plants and animals on regional or even global scales. But, new research shows that impacts can also preserve the signatures of ancient life at the time of an impact.
Some of the landscape underlying the massive Greenland ice sheet may have been undisturbed for 2.7 million years, ever since the island became completely ice-covered, according to researchers.
It has been reported that new archeological finds have pushed back the age of Rome. A team of archeologists discovered the remains of a wall built to channel water, which dates back to the ninth century BC. This goes against the traditional idea that Rome was founded on April 21, 753 BC by the twins Romulus and Remus.
Geologists who analyzed 40 meteorites that fell to Earth from Mars have unlocked secrets of the Martian atmosphere hidden in the chemical signatures of these ancient rocks. Their study shows that the atmospheres of Mars and Earth diverged in important ways very early in the 4.6-billion-year evolution of our solar system.
The skull of a newly discovered 325-million-year-old shark-like species suggests that early cartilaginous and bony fishes have more to tell us about the early evolution of jawed vertebrates— including humans— than do modern sharks. The new study shows that living sharks are actually quite advanced in evolutionary terms.
Serbian archaeologists have used heavy machinery to move a female mammoth skeleton— believed to be 1 million years old— from an open mine pit where it was unearthed nearly five years ago.
Researchers, working at the famous La Brea Tar Pits, are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.
Daddy longlegs have a single pair of eyes that help them navigate habitats in every continent except Antarctica. But a newly described 305-million-year-old fossil found in eastern France shows that wasn’t always the case.
Archaeologists are challenging the traditional view that Neanderthal childhood was difficult, short and dangerous. A research team is offering a new and distinctive perspective that suggests that Neanderthal children experienced strong emotional attachments with their immediate social group, used play to develop skills and maintained a significant role in their society.
One theory about the origin of life is that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world. Recent research has found that it may not have been as easy as previously assumed. Instead, the finds could provide a focus for the search for life on other planets.
Our fascination with mummies never gets old. Now, a museum is using the latest technology to unwrap their ancient mysteries. Scientists have used CT scans and sophisticated imaging software to go beneath the bandages.
Research into lower limb bones shows that our early farming ancestors in Central Europe became less active as their tasks diversified and technology improved.
Technical objections to the idea that Neanderthals interbred with the ancestors of Eurasians have been overcome, thanks to a genome analysis method. The technique can more confidently detect the genetic signatures of interbreeding than previous approaches and will be useful for evolutionary studies of other ancient or rare DNA samples.
Researchers have discovered a curious characteristic of the members of the human lineage: Homos are the only primates where— throughout their 2.5-million year history— the size of their teeth has decreased alongside the increase in their brain size.
Modern humans of European descent have a lot in common with their Neanderthal ancestors when it comes to genes related to fat breakdown in the brain. Researchers have found that people of European descent have three times the number of Neanderthal-like sequences in such genes compared to other modern human populations examined.
New evidence shows methane-producing microbes may be responsible for the largest mass extinction in Earth’s history.
The Israeli Antiquities Authority have unveiled 11 ancient burial boxes that were recovered by the Israeli Police. The authority says the boxes were recovered in Jerusalem when police observed a suspicious nighttime transaction involving two cars, four individuals and the 11 boxes.
Animals held such a prominent place in ancient Egyptian society that tens of millions were mummified, some going into the pharaohs' tombs. Others had their own special cemeteries, where they were buried in coffins as elaborately carved as those of royal family members.
A three-year study of ancient clam gardens in the Pacific Northwest reveals that coastal First Nations people of Canada used to reap superior harvests using rock-walled beach terraces.
Researchers have confirmed that, during the last ice age, iron fertilization caused plankton to thrive in a region of the Southern Ocean.
Why do we become saucer-eyed from fear and squint from disgust? These near-opposite facial expressions are rooted in emotional responses that exploit how our eyes gather and focus light to detect an unknown threat, according to a study.
Scientists have unveiled the discovery, naming and description of a sharp-clawed, 500-pound, bird-like dinosaur that roamed the Dakotas with T. rex 66 million years ago, and looked like an 11½-foot-long “chicken from hell.”
Researchers have brought back to life moss that was frozen in Antarctic ice for more than 1,500 years. This study is the first to show such long-term survival in any plant.
Archaeologists have found the oldest complete example in the world of a human with metastatic cancer in a 3,000-year-old skeleton.
