Whereas partner-serving phenotype is intuitively quantified as benefit release rate, molecular genetics revealed an example where this thinking fails, motivating a more general metric.

Shorebird flocks fly in a formation that re-creates the neighbor positioning relationship of a V-formation in cluster flocks of more than 1000 birds.

Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

Evolutionarily conserved hypoxic stress response genes are depleted for association with expression quantitative trait loci.

Differences in the response of cardiomyocytes to oxygen deprivation in humans and chimpanzees may explain why humans are more prone to certain heart diseases.

Comprehensive analyses of amylase duplications and salivary activity across mammals underscore the importance of recurrent copy number variation as a flexible and rapid evolutionary mechanism.

A new taxon from the Late Jurassic of southern Germany represents the second volant bird known from that time period and documents the improvement of flapping flight in bird evolution.

Animals living alongside humans have multiple copies of the gene for alpha-amylase, the enzyme that breaks down starchy foods, and high levels of this protein in their saliva.

Environmental heterogeneity can dramatically reduce the efficacy of selection and alter the neutral evolutionary dynamics in microbial range expansions.

In richer, more even communities, foragers form broad categories among their food resources that can select for convergence among signals, including mimetic resemblances.
