If released in the wild, current CRISPR-based gene drive systems designed to alter populations could spread much farther than intended, despite the evolution of drive resistance.

Multiple independent directional selection events on a neural substrate that underpins domain-general associative abilities partly explains independent occurrences of complex behavior in different lineages of mammals.
Stunning new scan data of an enigmatic fish from the Early Devonian of Australia, Ligulalepis, is identified as a stem osteichthyan, specifically, as the sister taxon to the 'psarolepids' plus crown osteichthyans.
A number of microbial eukaryotes have adapted to low oxygen conditions by acquiring a gene that allows their mitochondrial electron transport chain to continue to function when oxygen is scarce.
Deep mutational scanning of Env proteins from two transmitted-founder strains of HIV shows how the accessible evolutionary space changes as the virus evolves.
The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.
