The rat is much more than a simple model, and a better appreciation of the natural history of wild rats would increase its value as a research organism.
Machine learning and experimental tests of receiver bias identify signal components critical to correct species classification in guenons, linking face pattern diversity to selection for species discrimination.
Two studies suggest that a determined adversary may be able to obtain genetic information that they should not have permission to access from some genealogy databases.

Mutations elsewhere in the genome play critical roles in improving fitness during amplification and divergence of a gene encoding a weak-link enzyme whose inefficiency limits growth rate.

Hawaiian Caenorhabditis elegans harbor high levels of genetic diversity that might represent the complex patterns of ancestral diversity in the species prior to human influence.
Homology of vertebrate skull structures should be based on evolutionary continuity and an appreciation of germ layer origins and inductive signaling in the embryonic head.
In-planta ancestral protein resurrection of the female determinant of self-incompatibility specificity in Arabidopsis halleri demonstrates that two allelic variants currently segregating as distinct receptor-ligand combinations diverged through an asymmetrical process.
