The first gland of both the nervous system and endocrine system to mature during an embryo's development, it initially evolved more than 500 million years ago out of a "primitive" precursor organ in chordates known as the endostyle. /news/2025-08-jawless-parasite-uncovers-neural-crest.html Evolution Molecular & Computational biology Thu, 07 Aug 2025 12:37:53 EDT news673789068 Decline of seed-dispersing animals hinders fight against climate change Most trees in the Amazon (90%), the Atlantic Forest (90%), or the Cerrado, the Brazilian savanna-like biome (60%), depend on animals to disperse their seeds, ensure their reproduction, and keep the forest standing. Birds, mammals, fish, and even a species of amphibian play a crucial role in forest diversity around the world. However, this process has been disintegrating as populations of seed-dispersing animals have declined dramatically. /news/2025-08-decline-seed-dispersing-animals-hinders.html Plants & Animals Ecology Wed, 06 Aug 2025 13:16:46 EDT news673704960 Big heart, acute senses key to explosive radiation of early fishes, digital reconstruction indicates An international team led by scientists from the Canadian Museum of Nature and the University of Chicago reconstructed the brain, heart, and fins of an extinct fish called Norselaspis glacialis from a tiny fossil the size of a fingernail and found evidence of change towards a fast-swimming, sensorily attuned lifestyle well before jaws and teeth were invented to better capture food. /news/2025-08-big-heart-acute-key-explosive.html Evolution Paleontology & Fossils Wed, 06 Aug 2025 11:00:20 EDT news673596944 Dinosaur teeth serve as 'climate time capsules,' unlocking secrets of Earth's ancient greenhouse climate A previously unexploited source of information is now throwing new light on Earth's climate during the age of dinosaurs. Fossilized dinosaur teeth show that concentrations of carbon dioxide in the atmosphere during the Mesozoic Era, i.e., 252 to 66 million years ago, were far higher than they are today. This has been determined by researchers at the universities in Göttingen, Mainz, and Bochum following the analysis of oxygen isotopes in the dental enamel of dinosaur teeth. /news/2025-08-dinosaur-teeth-climate-capsules-secrets.html Earth Sciences Tue, 05 Aug 2025 12:45:22 EDT news673616711 Ocean oxygen decline threatens deep-sea fish populations and ocean health, new study warns An international study led by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), Spain, has investigated how marine ecosystems responded to past episodes of ocean deoxygenation. To do so, researchers studied fossil remains of lanternfish—one of the most abundant and important fish families of the deep ocean—preserved in seabed sediments of the Eastern Mediterranean, dating back more than 10,000 years. Their findings have been published in the journal Communications Earth & Environment. /news/2025-07-ocean-oxygen-decline-threatens-deep.html Ecology Paleontology & Fossils Thu, 31 Jul 2025 09:53:03 EDT news673174381 Unearthed teeth reveal human diversity in China during Middle Pleistocene The Centro Nacional de Investigación sobre la Evolución Humana (CENIEH) participated in a study, published in the Journal of Human Evolution, on human teeth unearthed at the Hualongdong site in Anhui Province, China.

Despite being one of the most studied fish in history, it continues to reveal new information that could transform our understanding of vertebrate evolution. This is revealed in a study published in the journal Science Advances by researchers from the University of São Paulo (USP) in Brazil and the Smithsonian Institution in the United States. /news/2025-07-fossil-fish-anatomy-reshaping-view.html Evolution Paleontology & Fossils Mon, 28 Jul 2025 16:01:02 EDT news672937255 Ancient caiman may have preyed on another apex predator—the giant 'terror bird' The La Venta fossil site in Colombia is home to a rich fossil record, yielding a particularly diverse set of vertebrate fossil assemblages. The giant terror bird (phorusrhacid) and caiman—a large crocodile-like reptile—were known to be two of the apex predators roaming this region during the middle Miocene epoch. Although the terror bird was a terrestrial predator and the caiman was an aquatic predator, new evidence shows that they occasionally crossed paths, and that these meetings did not go well for the terror bird. /news/2025-07-ancient-caiman-preyed-apex-predator.html Paleontology & Fossils Wed, 23 Jul 2025 11:10:01 EDT news672487729 The rubber hand illusion works on octopuses too Like humans, octopuses can fall for the rubber hand illusion and believe that a fake arm is theirs.
