Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
Body color change of locusts reveals a new 'palette effect' mechanism by which the red βCBP–β-carotene pigment complex acts as a switch to coordinate between black and green coloration.
The turquoise killifish from ephemeral pools in African savannah combines extremely short lifespan with a standard vertebrate body plan – ideal attributes for a laboratory animal.
A combination of genetics, experimental evolution and mathematical modelling defines information necessary to predict the outcome of short-term adaptive evolution.
A genetic screen reveals that two predicted glycosyltransferases promote rosette development and prevent cell clumping in one of the closest living relatives of animals, the choanoflagellate S. rosetta.

In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.
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.
