The observation that males evolve more quickly than females has been around since 19th century biologist Charles Darwin noted the majesty of a peacock's tail feather in comparison with the plainness of the peahen's.

The humble fruit fly has played a lead role on the scientific stage for more than a century. Tiny picnic pests to us, flies from a single species, Drosophila melanogaster, have provided a bounty of Nobel Prize-winning discoveries for researchers in the fields of genetics and developmental biology, and helped serve as models of human diseases such as Parkinson's and cancer.

 | New findings from insect studies at Queen's and U of T may help to protect our brains from extremely high fevers that sometimes trigger seizures, particularly in infants and small children. ...> Full Article |
 | Scientists thought that most new genes were formed from existing genes, but Cornell researchers have discovered a gene in some fruit flies that appears to be unrelated to other genes in any known genome. ...> Full Article |
 | Researchers at the University of Illinois have developed a simple and economical technique for imaging and mapping fruit fly chromosomes. This new approach will enable them to construct the first accurate map of the chromosomes and tease out the secrets hidden in their stripes. ...> Full Article |
 | A gene thought to play a relatively minor role in eye development is powerful enough on its own to initiate the formation of eyes in strange spots on a fruit fly's body, Indiana University Bloomington scientists have learned. ...> Full Article |
Transposable elements, sometimes called ‘selfish DNA’, can be responsible for insecticide resistance, according to scientists from the Universities of Exeter, Bath and Melbourne. Transposable elements (TEs) can ‘jump around’ the genome and cause mutations by inserting into the coding regions of genes and disrupting or altering, and in this case increasing, gene function.

Biologists at New York University have identified how different species use common genes to control their early development and alter how these genes are used to accommodate their own features.
