Bedbugs evolved more than 100 million years ago

Bedbugs -- some of the most unwanted human bed-mates -- have been parasitic companions with other species aside from humans for more than 100 million years, walking the earth at the same time as dinosaurs. Work by an international team of scientists, including the University of Sheffield, compared the DNA of dozens of bedbug species…

Neanderthals and modern humans diverged at least 800,000 years ago, new research shows

Neanderthals and modern humans diverged at least 800,000 years ago, substantially earlier than indicated by most DNA-based estimates, according to new research by a UCL academic. The research, published in Science Advances, analysed dental evolutionary rates across different hominin species, focusing on early Neanderthals. It shows that the teeth of hominins from Sima de los Huesos,…

Researchers identify largest carnivorous mammals ever to live on land

Twenty-three million years ago, a giant carnivore larger than any modern-day lion or polar bear stalked sub-Saharan Africa, according to the fossils of a previously undiscovered species that spent decades in a museum drawer. Portions of the animal's jaw, skull and skeleton, including enormous teeth, were discovered in a drawer at the National Museums of…

A Mysterious Infection, Spanning the Globe in a Climate of Secrecy

Last May, an elderly man was admitted to the Brooklyn branch of Mount Sinai Hospital for abdominal surgery. A blood test revealed that he was infected with a newly discovered germ as deadly as it was mysterious. Doctors swiftly isolated him in the intensive care unit. The germ, a fungus called Candida auris, preys on…

A Clever New Strategy for Treating Cancer, Thanks to Darwin

The large outer leaves of the vegetables were “literally riddled with holes, more than half their substance being eaten away.” With each step he took around the ravaged cabbages, tiny swarms of little ash-gray moths rose from the ground and flitted away. This was, it appears, the first record in the United States of the diamond­back…

Fossil Site Reveals Day That Meteor Hit Earth and, Maybe, Wiped Out Dinosaurs

Sixty-six million years ago, a giant meteor slammed into Earth off the coast of modern-day Mexico. Firestorms incinerated the landscape for miles around. Even creatures thousands of miles away were doomed on that fateful day, if not by fire and brimstone, then by mega-earthquakes and waves of unimaginable size. Now, scientists have unearthed a remarkable trove of fossils…

Neanderthals walked upright just like the humans of today

Neanderthals are often depicted as having straight spines and poor posture. However, these prehistoric humans were more similar to us than many assume. University of Zurich researchers have shown that Neanderthals walked upright just like modern humans -- thanks to a virtual reconstruction of the pelvis and spine of a very well-preserved Neanderthal skeleton found…

Great whites may have wiped out the biggest shark that ever lived

The megalodon -- also known as the biggest shark ever -- became extinct a million years earlier than previously thought, due to competition from much smaller great white sharks, according to new research. The full paper is published in the Journal of Life and Environmental Sciences. A team of scientists claim that the giant prehistoric predator,…

For Darwin Day, 6 facts about the evolution debate

Today is the 210th anniversary of Charles Darwin’s birth, a day now celebrated by some as Darwin Day. Darwin is best known for his theory of evolution through natural selection. When Darwin’s work was first made public in 1859, it shocked Britain’s religious establishment. And while today it is accepted by virtually all scientists, evolutionary theory…
