Despite the importance and dominance of angiosperms ("flowering plants") in the current ecosystem, it is rather surprising that we know so little about their origin and early evolution. Paleobotanists have been making efforts to decipher these enigmas. Unfortunately, their efforts are characterized by an "unbroken record of failure," as Tom Harris put it. https://phys.org/news/2026-08-permian-fossil-reveal-oldest.html Paleontology & Fossils Mon, 31 Aug 2026 17:00:01 EDT news707392802 Imagine the Western Plains of North America, from Texas to Alaska, submerged under a broad, shallow seaway. To the west lay the ancestral Rocky Mountains. To the east were low-lying plains traversed by large, sluggish rivers. https://phys.org/news/2026-08-rare-dinosaur-tracks-coniacian-age.html Paleontology & Fossils Wed, 26 Aug 2026 18:00:05 EDT news706968249 A unique cache of plant fossils from volcanic deposits in New Mexico contradicts the common narrative that flowering plants were minor players in Earth's forests until dinosaurs disappeared 66 million years ago. https://phys.org/news/2026-06-fossils-upend-catastrophist-narrative-flourished.html Evolution Thu, 25 Jun 2026 14:00:11 EDT news701590742 A new study published in Zoological Journal of the Linnean Society describes, for the first time in detail, the soft tissues preserved in Montsecosuchus depereti, a Lower Cretaceous crocodylomorph from the Pedrera de Meià site in the province of Lleida (Catalonia, Spain). The analysis, based on ultraviolet light, provides new clues to the coloration of these animals, as well as the evolution of the respiratory system.

But new research suggests that this widely used method may have been underestimating the lifespan of many flowering trees—sometimes by centuries. A new international study published in Radiocarbon shows that radiocarbon dating can dramatically extend the known maximum age of broadleaved trees, revealing that many species live far longer than previously thought. https://phys.org/news/2026-03-radiocarbon-dating-rewrites-angiosperm-trees.html Plants & Animals Tue, 03 Mar 2026 19:40:05 EST news691776283 Angiosperms, also known as flowering plants, represent the most diverse group of seed plants, and their origin and evolution have long been a central question in plant evolutionary biology. Whole-genome duplication (WGD), or polyploidization, is widely recognized as a key driver of the origin and trait evolution of both seed plants and angiosperms. https://phys.org/news/2026-01-dosage-sensitive-genes-genome-duplications.html Evolution Fri, 02 Jan 2026 14:00:08 EST news686578691 As global temperatures rise, Cold Spring Harbor Laboratory (CSHL) scientists work to grow stronger, more resilient crops. Yet, this process is challenging. Plants often have several related genes that control desirable traits, such as size or drought resistance. Finding genes with overlapping functions, or "redundant genes," is a near-impossible scavenger hunt. https://phys.org/news/2025-12-ai-gene-redundancies-crop.html Molecular & Computational biology Mon, 08 Dec 2025 12:28:24 EST news684419281 A research team led by Prof. Huang Diying from the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences (NIGPAS) has identified three species of Jurassic orthopterans—an insect group that includes grasshoppers, crickets and katydids—with forewing patterns nearly identical to the leaves of bennettitales, an extinct, cycad-like seed plant. https://phys.org/news/2025-09-jurassic-insects-leaf-wings-china.html Evolution Fri, 05 Sep 2025 13:41:04 EDT news676298462 The first time I saw the Ada Tree, I felt tiny. It was October 2015, just days after arriving in Victoria to study mountain ash forests. During a visit to the Central Highlands, we went to see the Ada Tree—one of the largest mountain ash specimens, standing 76 meters tall (equivalent to a 20-story building), with a trunk 5 meters wide. https://phys.org/news/2025-08-giants-australian-forest.html Plants & Animals Thu, 21 Aug 2025 12:16:21 EDT news674997371 Heat-stressed Victorian mountain ash forests are thinning fast, turning from carbon sinks to carbon sources, new research reveals. https://phys.org/news/2025-08-stressed-australian-forests-thinning-fast.html Earth Sciences Thu, 21 Aug 2025 11:27:04 EDT news674994421 The endangered South African cycad Encephalartos horridus may resemble a relic from the Jurassic age, but the species itself evolved long after dinosaurs disappeared. Still, it carries a biochemical legacy inherited from its distant ancestors—plants that once thrived alongside Jurassic fauna. A team led by Hiroshima University (HU) researchers found that its spiky, silvery-blue leaves owe their color not to pigment, but to a wax-based optical effect produced by a lipid compound that may date back to the dawn of land plants. https://phys.org/news/2025-08-rare-cycad-wax-crystals-conjure.html Plants & Animals Fri, 08 Aug 2025 11:15:32 EDT news673870526 Plant fossils found in the abdomen of a sauropod support the long-standing hypothesis that these dinosaurs were herbivores, finds a study published in Current Biology. The dinosaur, which was alive an estimated 94 to 101 million years ago, ate a variety of plants and relied almost entirely on its gut microbes for digestion. https://phys.org/news/2025-06-fossilized-dinosaur-gut-sauropods.html Paleontology & Fossils Mon, 09 Jun 2025 11:00:06 EDT news668417281 They are very tiny, but they are a key source of information when it comes to Earth's evolutionary history: pollen grains are usually no larger than 20 micrometers, or 0.02 millimeters. Using these tiny particles, a research team at Leibniz University Hannover (LUH) and the University of Bonn has managed to pinpoint the earliest emergence of flowering plants, so-called angiosperms, much more precisely. https://phys.org/news/2025-05-blooming-earth-million-years-pollen.html Plants & Animals Tue, 20 May 2025 13:30:04 EDT news666966602 A wild ginger has a clever trick up its sleeve to lure in pollinators. No, it's not a sweet fragrance that fills the air, but the foul stench of rotting flesh and dung. To attract carrion-loving flies and beetles, the flowers of the plant genus Asarum brew a malodorous chemical called dimethyl disulfide (DMDS) with the help of a disulfide synthase (DSS)—an enzyme derived from another enzyme, methanethiol oxidase (MTOX), found in both animals and plants. https://phys.org/news/2025-05-gene-mutations-mimic-foul-odor.html Evolution Mon, 12 May 2025 09:02:53 EDT news666259362 A joint research team has discovered a fossil belonging to a previously unknown genus and species of mammal in the Late Cretaceous (100–66 million-year-old) strata of Mongolia's Gobi Desert. https://phys.org/news/2025-04-fossil-mammal-species-age-dinosaurs.html Paleontology & Fossils Tue, 29 Apr 2025 02:22:23 EDT news665112138 A research group led by Nagoya University in Japan has discovered a new tissue in plants that is essential for seed formation.
