Research using genetic data from Turquet’s octopus suggests that the West Antarctic Ice Sheet collapsed during the Last Interglacial period due to modest temperature increases.…
A new study indicates that human evolutionary traits, especially cultural adaptation, could hinder solving global environmental problems, such as climate change. It highlights the need…
A new study suggests that the evolution of the human brain’s increased size may be attributed to the consumption of fermented foods, offering an alternative…
Skeleton of the early dinosaur Coelophysis bauri from the Late Triassic. The protracted restructuring of Early Jurassic terrestrial ecosystems coincided with the diversification of dinosaurs.…
Lund University researchers have uncovered that the genetic color variation in female bluetail damselflies, including a male-mimicking form, originated over five million years ago. This…
A study on wild gray mouse lemurs by the German Primate Center revealed that higher cognitive skills and exploratory behavior contribute to longer lifespans. The…
A great hammerhead shark’s two eyes can be 3 feet apart on opposite sides of its skull. Why do hammerhead sharks have hammer-shaped heads? Hammerhead…
A view from the summit of Volcán Salín, one of three Andean volcanoes where researchers uncovered the mummified cadavers of mice. Analyses of the mummies,…
A Stanford study using genetic and molecular tools has unraveled the mystery of starfish anatomy, revealing that their “head” is distributed across multiple regions, including…
Researchers used computer models to investigate the evolutionary role of aging. They challenge the notion that aging has no positive function, suggesting it might expedite…
A comprehensive study confirms the antagonistic pleiotropy theory of aging, showing a genetic correlation between high reproduction and shorter lifespan. However, it highlights that environmental…
Recent research has shown that the formation of greenalite in ancient oceans played a crucial role in determining the availability of certain metals, such as…
New research provides fresh insights into evolutionary stasis by studying the survival patterns of lizards in their natural habitat. Contrary to traditional beliefs, the study…

Pictured is an early planula larval stage of the sea anemone Aiptasia (cyan nuclei and green stinging cells) preying on a crustacean nauplius (green) of…
MIT biologists discovered that a scaffolding protein called TCOF1 is responsible for the formation of a biomolecular condensate called the fibrillar center, which forms within…
Confocal microscopy image of nuclei, colored by depth, of Trichoplax sp. H2, one of the four species of placozoan for which the authors of the…
Tenerife’s flora has a surprisingly high diversity in terms of forms and functions. In the background: Pico del Teide, Spain’s highest mountain at 3715 meters.…
