| New species of human ancestor named: Homo bodoensis Posted: 28 Oct 2021 11:36 AM PDT Palaeoanthropologists have announced the naming of a new species of human ancestor, Homo bodoensis. This species lived in Africa during the Middle Pleistocene, around half a million years ago, and was the direct ancestor of modern humans. |
| Intriguing insect fossils preserved in amber Posted: 28 Oct 2021 11:36 AM PDT What zoologists have discovered in samples of ancient amber -- insect larvae with unusual morphologies and larvae of early flying insects. |
| Evidence of prehistoric human activity in Falkland Islands Posted: 27 Oct 2021 12:07 PM PDT Findings from a new study suggest that Europeans were not the first people to ever set foot on the Falkland Islands. Most of the evidence from the investigation indicates that Indigenous South Americans likely traveled to the Falkland Islands between 1275 C.E. and 1420 C.E., although earlier dates cannot be ruled out. |
| More than ceremonial, ancient Chaco Canyon was home, new study says Posted: 27 Oct 2021 12:07 PM PDT New research reveals ancestral puebloans in ancient Chaco Canyon interacted with local ecosystem to thrive for more than a millennium, but unsustainable deforestation practices likely contributed to destabilizing environmental impact prior to their final exodus. |
| Tiny pterosaurs dominated Cretaceous skies Posted: 27 Oct 2021 09:20 AM PDT The newly hatched juveniles of large and gigantic pterosaurs likely out-competed other smaller adult pterosaur species to dominate the Late Cretaceous period around 100 million years ago, a new study has found. |
| Red paint on 1,000-year-old gold mask from Peru contains human blood proteins Posted: 27 Oct 2021 09:19 AM PDT Thirty years ago, archeologists excavated the tomb of an elite 40--50-year-old man from the Sicán culture of Peru, a society that predated the Incas. The man's seated, upside-down skeleton was painted bright red, as was the gold mask covering his detached skull. Now, researchers have analyzed the paint, finding that, in addition to a red pigment, it contains human blood and bird egg proteins. |
| Powerful X-ray technique finds new degradation-inducing materials in British shipwreck Posted: 27 Oct 2021 09:19 AM PDT In 1545, King Henry VIII's favorite ship, the Mary Rose, capsized and sank in the Battle of the Solent defending England and Portsmouth from a French invasion fleet. The wreck remained on the seabed until 1982 when it was salvaged in a widely viewed televised event. Now, it is a time capsule for 16th century Tudor society, and conservators are working to preserve it for future generations. Scientists use X-ray analysis to identify previously undetected products in the wood -- nanoparticles originating from underwater bacterial activity. |
| The surprising origins of the Tarim Basin mummies Posted: 27 Oct 2021 09:19 AM PDT Researchers have determined the genetic origins of Asia's most enigmatic mummies. Once thought to be Indo-European speaking migrants from the West, the Bronze Age Tarim Basin mummies are revealed to be a local indigenous population with deep Asian roots and taste for far-flung cuisine. |
| Fossil dental exams reveal how tusks first evolved and why they are unique only to mammals Posted: 27 Oct 2021 05:53 AM PDT Researchers trace the first tusks back to ancient mammal relatives that lived before the dinosaurs and shed light on the evolution of mammalian tusks by first defining what makes a tusk a tusk. |
| What big teeth you have: Tooth root surface area can determine primate size Posted: 26 Oct 2021 06:54 AM PDT Researchers have developed formulas that can calculate the body size of a primate based on the root size of its teeth. The formulas could allow researchers to make use of partial and incomplete fossils in order to learn how ancient primates -- including human ancestors -- interacted with their environment. |
