Latest Hox gene Stories
Lamprey — slimy, eel-like parasitic fish with tooth-riddled, jawless sucking mouths — are rather disgusting to look at, but thanks to their important position on the vertebrate family tree, they can offer important insights about the evolutionary history of our own brain development.
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.
A new study found that our fish ancestors had the genetic machinery for fingers, but these structures did not develop until the evolution of limbs in amphibians.
A decade ago, gene expression seemed so straightforward: genes were either switched on or off.
A multidisciplinary international research project has identified the mechanism responsible for generating our fingers and toes.
Vertebrates' transition to living on land, instead of only in water, represented a major event in the history of life.
Surprise discovery contradicts theories about anatomy exclusive to land animals
Biologists have long assumed that all jawed vertebrates possess a full complement of nearly identical genes for critical aspects of their development.
Why don't our arms grow from the middle of our bodies?
- Pertaining to the surface or end opposite to the mouth in a radiate animal.
