The identification of 31 neuropeptide GPCRs in the sea anemone Nematostella vectensis provides a rich resource to study peptidergic signaling in cnidarians and suggests that cnidarian and bilaterian peptidergic systems diversified independent from each other from a few ancestral systems.

Studies of the starlet sea anemone provide important insights into the early evolution of the circadian clock in animals.

Diversified genetic and transcriptional changes in parallel evolved Escherichia coli populations for improved growth revealed that the evolution complementing genome reduction was like all roads leading to Rome.

Enantiornithine birds reached similar dietary diversity to modern birds in a similar amount of time many millions of years earlier, but how exactly they did that requires further research.

An individual-based model framework of sub-exponentially growing replicator systems suggests that parabolic dynamics could have been able to maintain genetic diversity and circumvent the error threshold problem during early evolution.

Dormancy during non-life-threatening periods that are unfavorable for reproduction may be more widespread than previously appreciated.

The rapidly evolving X-linked MIR-506 family miRNAs function to enhance sperm competitiveness and male reproductive fitness in mice.

Evolution-guided structure-function analyses reveal that CD4 transmembrane and intracellular juxtamembrane motifs play a more profound role in initiating pMHCII-specific TCR-CD3 signaling than previously characterized CD4-Lck interactions.

Disentangling the different selective forces shaping the evolutionary dynamics of transposable elements (TEs) in the wild grass Brachypodium distachyon.

Columnar architectures, developed in early Cambrian phosphatic-shelled brachiopods, are highly biologically controlled and organic-matrix mediated, which sheds new light on the evolution and adaptation of biomineralization during the Cambrian explosion.
