An international team of researchers led by LMU paleontologist Bettina Reichenbacher has managed to classify fossils of one of the most species-rich fish groups into a family tree for the first time. Materials provided by Ludwig-Maximilians-Universität München. Note: Content may…
Developmental tracing in mice shows the TMJ disc forms independently of the condyle with a tendon-like molecular signature, supporting its evolutionary origin from a trapped tendon.
Published in Applied Microscopy, the study investigates how the structural organization of the integument supports the species' survival in fluctuating coastal and estuarine environments.
A research team from the University of Helsinki has discovered a tree hyrax in the Taita Hills, Kenya, which may belong to a species previously unknown to science. The discovery, which was part of a study of the vocalisations of…
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods -- say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, in evolutionary terms, have higher rates…
A new study finds no shared pattern in bone histology, microanatomy or life history traits that distinguishes neotenic salamanders from metamorphosing ones, including the Permian fossil Apateon. Neoteny, the retention of larval traits into sexual maturity, has long fascinated biologists…
A new reconstruction of spore evolution shows that the ancestor of all land plants bore trilete spores, forcing a recalibration that places land plant origins in the Late Ordovician, about 55 million years later than previous molecular estimates.
Development, Genes and Evolution, one of the oldest journals in developmental biology, has published its last issue under its current name. In a farewell editorial, Editor-in-Chief Angelika Stollewerk announced that she is stepping down at the end of 2024 and that…
October 28, 2026 / 6:55 PM MDT / CBS Colorado The Denver Museum of Nature & Science is preparing to display one of the rarest dinosaur fossils ever discovered: a footprint from what researchers have identified as the world's only known adult Tyrannosaurus rex trackway. The…
Newswise — Women in Herpetology: 50 Stories from Around the World unveils the inspiring journeys of 50 women from 50 countries and regions who have dedicated their lives to studying amphibians and reptiles. This groundbreaking book showcases the determination, passion, and love for these…
