Abstract. Biases in molecular evolution can significantly influence evolutionary trajectories. They have been described in a variety of contexts, such as d

Abstract. Exoskeletons define arthropods, providing support for segmented bodies and appendages while protecting against environmental stress and predation

Nature Ecology & Evolution - Citizen science platforms must mitigate against the threat of generative AI

The genetic program of animal development is conserved, but its rate of execution varies across species. Heterochrony, shifts in the relative timing of developmental events, generates phenotypic varia...

A new study shows that over 90% of insect biomass declines are driven by shrinking species numbers, posing a risk to ecosystem function.

The Lepidoptera, butterflies and moths, display an astonishing diversity of spatial orientation strategies essential for survival, reproduction, and ecological success. These spatial orientation strat...

Body size variation in vertebrates is a complex polygenic trait, tightly correlated with numerous aspects of a species’ biology, ecology, and physi...

Mulhair et al. uncover a functional bicoid in non-cyclorrhaphan flies, pushing the gene's origin back by ∼20 million years. Reassessing the Diptera phylogeny using the largest dataset to date permits ...

The evolutionary dynamics of immune genes are shaped by diverse selective pressures, yet the relative roles of gene-level traits, functional specialization, and pathway context remain poorly understoo...

Bizarre discovery of interspecies cloning “almost impossible to believe,” biologists say

Since 1993 Expasy has been the reference of Bioinformatics Resources. Learn everything about Expasy

The Drosophila Genetic Database, FlyBase, is on the brink of collapse due to the sudden termination of the FlyBase NIH grant, which includes salaries for 5 literature curators based at the University ...

Mirasaura grauvogeli had a featherlike crest and a tail like a monkey. “It's been a long time since I've been so blown away by a new fossil discovery.”
