| How did vertebrates first evolve jaws? Posted: 28 Jun 2022 05:33 AM PDT Scientists reveal clues about the evolutionary origin of jaws by studying the embryonic development of zebrafish -- an approach known as 'evo-devo.' Using imaging and cell tracing techniques in zebrafish, researchers who conducted the study conclusively showed that the pseudobranch originates from the same mandibular arch that gives rise to the jaw. |
| Fossils in the 'Cradle of Humankind' may be more than a million years older than previously thought Posted: 27 Jun 2022 01:59 PM PDT For decades, scientists have studied these fossils of early human ancestors and their long-lost relatives. Now, a dating method developed by geologists just pushed the age of some of these fossils found at the site of Sterkfontein Caves back more than a million years. This would make them older than Dinkinesh, also called Lucy, the world's most famous Australopithecus fossil. |
| Virus discovery offers clues about origins of complex life Posted: 27 Jun 2022 09:49 AM PDT Researchers have discovered the first viruses infecting a group of microbes that may include the ancestors of all complex life. The discovery offers tantalizing clues about the origins of complex life and suggests new directions for exploring the hypothesis that viruses were essential to the evolution of humans and other complex life forms. |
| Ancient microbes may help us find extraterrestrial life forms Posted: 27 Jun 2022 07:02 AM PDT Using light-capturing proteins in living microbes, scientists helped reconstruct what life was like for some of Earth's earliest organisms. These efforts could help us one day recognize signs of life on other planets. |
| The heat is on: Traces of fire uncovered dating back at least 800,000 years Posted: 27 Jun 2022 07:01 AM PDT Scientists reveal an advanced, innovative method that they have developed and used to detect nonvisual traces of fire dating back at least 800,000 years -- one of the earliest known pieces of evidence for the use of fire. The newly developed technique may provide a push toward a more scientific, data-driven type of archaeology, but -- perhaps more importantly -- it could help us better understand the origins of the human story, our most basic traditions and our experimental and innovative nature. |
| Posted: 23 Jun 2022 06:12 AM PDT The 'missing link' between bacterial cells and human and plant cells offers key to the process of eukaryogenesis, the point at which animal and plant cells diverge from bacteria. |
