Protein coding genes strongly support a sister group relationship between Placozoa and Cnidaria to the exclusion of Bilateria, contradicting previous phylogenies, which have likely been misled by pervasive compositional heterogeneity.

Regulatory sequences downstream of a key limb identity gene are required for normal sizes of leg bones, and are changed in wild species with dramatic alterations in pelvic structures.

High-throughput, integrative taxonomy has a crucial role to play in ensuring that the resources in our oceans are managed and developed in a sustainable manner.

Hamilton's rule can be violated when costs and benefits of cooperation are defined using the counterfactual method, and when they depend on the cooperation of others.

Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.

A family of proteins (OSCA/TMEM63) that encode mechanosensitive ion channels has been characterized in plants, flies, and mammals.

Rats act as if they expect that the delays associated with temporal cues will covary due to a common causal factor.

Extraembryonic tissue spreading in the scuttle fly Megaselia abdita requires mechanical decoupling from the underlying yolk sac.

Use of experimental manipulation demonstrates that social/solitary feeding behaviors are unrelated to the fitness gains conferred by causative alleles in two previously identified genes.

Skeletal muscle performance sets the course of rapid speciation by defining the evolutionary trajectory of reproductive behavior.
