The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.
The ascidian Ciona integrates visual information from two photoreceptor types through convergent excitatory and disinhibitory circuits, thereby evoking swim behaviors.
A gene regulatory network model provides a simplified explanation of the molecular interactions that orchestrate muscle development in the sea urchin embryo.
Shared complexities of backbone segmentation between cartilaginous fishes and tetrapods originate much earlier in vertebrate evolution than previously thought.
The evolutionary loss of the main enzyme required for ketone body biosynthesis suggests that alternative strategies to provide energy for large brains during fasting evolved repeatedly in mammals.
