| Primates’ ancestors may have left trees to survive asteroid Posted: 13 Oct 2021 08:40 AM PDT When an asteroid struck 66 million years ago and wiped out dinosaurs not related to birds and three-quarters of life on Earth, early ancestors of primates and marsupials were among the only tree-dwelling (arboreal) mammals that survived, according to a new study. |
| Posted: 13 Oct 2021 08:40 AM PDT Human feces don't usually stick around for long -- and certainly not for thousands of years. But exceptions to this general rule are found in a few places in the world, including prehistoric salt mines of the Austrian UNESCO World Heritage area Hallstatt-Dachstein/Salzkammergut. Now, researchers who've studied ancient fecal samples (or paleofeces) from these mines have uncovered some surprising evidence: the presence of two fungal species used in the production of blue cheese and beer. |
| Popular theory of Native American origins debunked by genetics and skeletal biology Posted: 13 Oct 2021 05:16 AM PDT A widely accepted theory of Native American origins coming from Japan has been attacked in a new scientific study, which shows that the genetics and skeletal biology 'simply does not match-up.' |
| Cracking the case of how one of the earliest predators hunted Posted: 12 Oct 2021 12:47 PM PDT Early in animal evolution, complex life was mostly limited to the sea floor. But a few organisms evolved to move through the water, giving them a big competitive advantage over those left scuttling around in the mud. |
| How human disease-causing genes prevent adaptations to remove them Posted: 12 Oct 2021 10:07 AM PDT Scientists have identified a new detrimental effect of genes that cause inherited diseases. |
