A detailed discussion of the broad range of immediate, delayed, cumulative, and third-party fitness consequences arising from outgroup conflict showcases the importance of this neglected aspect of sociality as a powerful and widespread evolutionary force.

Mammals evolved an invasive placenta early in the origins of pregnancy.

Cranial endocasts of fossil and extant lungfish, analysed via tomography and novel principle component analyses designed for use with missing data, show that lungfish forebrain and inner ear regions show the most variation in brain shape evolution through time.

Analyses of spindle genes with missense changes in modern humans reveal evidence for positive selection since the split with archaic humans and show that modern humans interacted with Neandertals more than once in the past 200,000 years.

An interdisciplinary approach combining high throughput genotype-to-phenotype mapping, population genetic simulations, and experimental evolution provides an answer to the question of how populations evolve new functions by providing tests of the role antagonistic coevolution plays in pressuring populations to innovate.

The development of diverse tooth shapes among vertebrates, from sharks to mammals, is a highly conserved process, utilising a similar dental signalling centre for more than 400 million years.

The tooth shape of sharks and mice are regulated by a similar signaling center despite their teeth having very different geometries.

The underlying neurophysiology of the lateral line system in blind cavefish (Astyanax mexicanus) has evolutionarily converged on elevated afferent neuron activity and partial loss of function in inhibitory efferent neurons, both of which contribute to enhanced sensitivity to flow stimuli.

Genetic barriers to gene flow maintain divergent linked substitution rates in hybridization.

Joint sequence, structure, and phylogenetic analyses identify highly conserved features in transmembrane domains of transient receptor potential (TRP) ion channel proteins that offer a novel explanation for how TRPs could integrate stimuli into cellular signals.
