A new discovery shows how wing spots evolved in a species of polka-dotted fruit fly, and underscores the concept that evolution likes to tinker with existing genetic machinery.
In a tour-de-force of evolutionary sleuthing, researchers have traced a yellow-to-black color change in African fruit flies to five single-letter genetic mutations.
HHMI research shows that evolution is an incessant tinkerer when it comes to complex traits.
The journal Science has announced that the scientific ”Breakthrough of the Year" is evolution in action. Recent experiments by four HHMI investigators were among those mentioned by Science as having provided evidence of evolution in action during the past year.
La revista Science ha anunciado que el avance científico del año es la evolución en acción. Experimentos recientes de cuatro investigadores del HHMI que proporcionan evidencias de la evolución en acción se encuentran entre los experimentos más importantes del año que fueron mencionados por Science.
HHMI researchers have shown how proteins conserved by evolution can evolve new functions while retaining their old ones, enabling new animal forms to arise.
By analyzing the genetic origin of a modest spot on a fruit fly wing, HHMI researchers have discovered a molecular mechanism that explains, in part, how new patterns can evolve.
Single-celled organism harbors protein sensor that was thought to be restricted to multicellular animals.
Molecular studies of a family of genes are pruning branches from the old evolutionary tree.
The discovery of a common genetic circuit for limb formation in arthropods is not only important for developmental biology, but also holds promise as an important new window to the past.
