| Researchers discover crocodile species that likely preyed on human ancestors Posted: 15 Jun 2022 10:08 AM PDT Researchers have discovered two new species of crocodiles that roamed parts of Africa between 18 million and 15 million years ago and preyed on human ancestors. The giant dwarf crocodile species, called Kinyang, mysteriously disappeared, possibly due to changes in the climate. |
| Origins of the Black Death identified Posted: 15 Jun 2022 08:32 AM PDT The Black Death, the biggest pandemic of our history, was caused by the bacterium Yersinia pestis and lasted in Europe between the years 1346 and 1353. Despite the pandemic's immense demographic and societal impacts, its origins have long been elusive. Now, scientists have obtained and studied ancient Y. pestis genomes that trace the pandemic's origins to Central Asia. |
| Parasitic worms reveal new insights into the evolution of sex and sex chromosomes Posted: 15 Jun 2022 07:28 AM PDT Studying two highly divergent phyla of worms that contain numerous parasites that cause human and livestock diseases, new research sheds light on how sexual reproduction and subsequent great diversity of sex chromosomes might have evolved. |
| A large predator from the Pyrenees Posted: 15 Jun 2022 07:28 AM PDT A fossilized lower jaw has led an international team of palaeontologists to discover a new species of predator that once lived in Europe. These large predators belong to a group of carnivores colloquially known as 'bear dogs'. They could weigh around 320 kilograms, appeared 36 million years ago before becoming extinct around 7.5 million years ago. |
| River belt discovery helps scientists understand ancient rivers Posted: 14 Jun 2022 03:41 PM PDT A researcher has come up with a rule that connects channel belts to river patterns, finding that, in general, the more channels a river has, the narrower its channel belt. Since the physics shaping rivers is the same over time and place, the rule should hold for ancient rivers and rivers on other planets, too. |
| Earliest record of wildfires provide insights to Earth's past vegetation and oxygen levels Posted: 14 Jun 2022 09:27 AM PDT While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires have been a long-standing part of Earth's systems without the influence of humans for hundreds of millions of years. |
| Pioneering study shows climate played crucial role in changing location of ancient coral reefs Posted: 14 Jun 2022 09:26 AM PDT Prehistoric coral reefs dating back up to 250 million years extended much further away from the Earth's equator than today, new research has revealed. |
| Scientists provide explanation for exceptional Tonga tsunami Posted: 13 Jun 2022 09:45 AM PDT Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year. |
