Sea lamprey studies show remarkably conserved gene expression patterns in jawless versus jawed vertebrates.
It’s difficult to identify a single evolutionary novelty in the animal kingdom that has fascinated and intrigued mankind more than the lantern of the firefly.
According to researchers at the Max Planck Institute for Plant Breeding Research in Cologne, the hairy bittercress (Cardamine hirsuta) has a particular gene to thank for its dissected leaves.
University of Adelaide researchers have taken a step forward in unraveling the causes of a commonly inherited intellectual disability, finding that a genetic mutation leads to a reduction in certain proteins in the brain.

Biologists have long assumed that all jawed vertebrates possess a full complement of nearly identical genes for critical aspects of their development.
A new analysis has found that the first genes which appeared after the primate branch split are more likely to be expressed in the developing human brain.
