The most noticeable difference between the modern human face and that of the hunter-gatherers, who lived on Earth over 200,000 years ago, is the forehead. While we now have flat, smooth foreheads with visible eyebrows, our ancestors sported a pronounced brow ridge. Experts have always believed that the thick rim, and the evolution to the beautiful tufts of facial hair, served a physiological function. Now, a team of scientists from UK’s University of York and Portugal’s Universidade do Algarve suggest the distinct facial features help with our social relationships.

Researchers have always maintained that Triassic dinosaurs were small, chicken-sized critters, and that it was not until the Jurassic period — about 180-million years ago — that massive herbivorous sauropods, like the Diplodocus and Brachiosaurus, emerged. However, the discovery of a new dinosaur species in Argentina suggests that the animals achieved gigantism during the late Triassic period, about 30 million years earlier than previously believed.
Large predators are increasingly appearing in unexpected places — alligators in saltwater marshes, killer whales in rivers, and mountain lions far away from the closest mountain. Experts hypothesize that as successful conservation efforts increase the local populations of these predators, they are moving beyond their usual habitats in search of food. However, Brian Silliman, professor of marine conservation biology at Duke University has a different theory. He believes the animals are recolonizing habitats they lived and hunted in for centuries — before human activity pushed them to the brink of extinction, and long before researchers began studying them.
14,000-Year-Old Charred Breadcrumbs Discovered In Jordan Prove Our Nomadic Ancestors Were Adept Bakers
Archeologists had always assumed that our early ancestors began baking about 10,000 years ago, after they gave up their nomadic way of life and became farmers. The scientists hypothesized that the abundant grain harvests inspired ancient humans to mill the crop into flour and make bread. However, the discovery of the charred remains of a flatbread that dates back over 14,000 years seems to indicate humans began baking long before their transition to an agricultural-based life.
There are numerous meteor showers throughout the year. However, few are as popular, or as reliable, as the Perseids. The celestial show, which occurs when Earth passes through the path of Comet Swift-Tuttle, usually starts in mid-July and continues until the last week of August. This year, the best time to view the event will be between August 11 to 13, when our planet traverses through the densest comet dust and the meteors are the brightest and most frequent.
With an estimated 100,000 marine animals being choked, suffocated, or injured by plastic every year, the danger posed by the trillions of pieces of polymer floating in our oceans is well-known. However, given that most of the microplastics measure less than 0.5mm in diameter, collecting them is a challenging task. Now, some Dutch environmentalists have devised a way to not only capture plastic waste before it reaches the open seas and disintegrates, but to also use it to create a public park and wildlife sanctuary.
When two German hikers stumbled upon a dead body buried in ice in the Italian Otzal Alps in 1991, they had no idea that the pristine remains were those of a male who had inhabited Earth almost 5,300 years ago. Named Ötzi after the mountains where he had lain for thousands of years, the Iceman is Europe’s oldest-known natural human mummy.
On Tuesday, July 10, 2018, the world watched with bated breath as an international team of rescuers safely extracted the two remaining members of the Moo Pa, or, Wild Boar, soccer team from a flooded cave in Thailand. The twelve boys, aged between 11 and 17, along with their coach, Ekkapol Ake Chantawong, had been trapped inside the intricate seven-mile long Tham Luang Nang Non cave system in northern Thailand's Chiang Rai Province for over two weeks.
