The seemingly simple, constitutive response of the patched/Ptch1 gene to Hedgehog signaling is in fact regulated by large batteries of context-specific Hedgehog-responsive enhancers in both fly and mouse, allowing tissue-specific tuning of the Hedgehog pathway in animal development and evolution.

The analysis of 20 coral genomic datasets provides unprecedented insights into what makes reef-building corals unique, including the evolution of novel gene families involved in biomineralization, signaling and stress responses that have led to their evolutionary success throughout the Phanerozoic Eon.

Viruses drive adaptation at the scale of the whole proteome and not only in antiviral proteins in mammalian hosts.

Cell cycle network evolution in a fungal ancestor was punctuated by the arrival of a viral DNA-binding protein that was permanently incorporated into the regulatory network controlling cell cycle entry.

Increasing awareness that many causal links in biology might be bi-directional could overcome biases and improve scientific reasoning.

The discovery of a fossil heart in Rhacolepis buccalis demonstrates that it is possible to scrutinize the fossil record for important clues on cardiac structure and evolution.

Both gill musculature and the evolutionarily conserved cucullaris muscle are derived from unsegmented mesoderm adjacent to the first 3 somites, extending the posterior limit of cranial mesoderm.

Many natural isolates of budding yeast carry extra chromosome copies and show lower-than-expected expression at a subset of amplified genes, which show unique evolutionary signatures.
