Lizards that live in the Greater Antilles exploit a large range of skeletal variations to adapt to similar habitats, in defiance of the theory of plasticity-led evolution.

Two new unicellular organisms reveal that coordinated contractions of groups of cells using actomyosin predated animal multicellularity during evolution.

Similar patterns of genomic divergence have been observed in the evolution of plant species separated by oceans.

Super-resolution microscopy sets a new strategy to comprehend the membrane organization of γ-secretase at single complex resolution identifying nanodomain associations and its diffusion in situ in the living membrane.

A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

In an in vitro RNA replication system, an RNA spontaneously diversifies and continuously evolves through coevolution with parasitic entities.

Regulatory evolution allows paralogs to escape from strucural pleiotropy.

Cooperativity between two transcription regulators occurs through protein-protein interactions with a general transcription factor complex and potentiates the parallel evolution of their DNA binding sites.

A gene duplication event has permitted the functional specialization of a homeodomain transcription factor through changes in exon-intron organization and these changes have supported the evolution of a major, phylum-level morphological novelty.

Life-threatening S. aureus infections emerge from commensal nose bacteria in association with repeatable adaptive evolution.
