Key connection
Scientists have long suggested that the best way to settle the debate about how phenotypic plasticity may be connected to evolution would be to identify a mechanism that controls both. Harvard researchers say they have discovered just such a mechanism in insulin signaling in fruit flies.

Solving a biological mystery
A team of Harvard researchers has shown that insects like crickets possess a variation of a gene — called oskar — that is critical to the production of germ cells in “higher” insects. That discovery suggests that the oskar gene emerged far earlier in insect evolution than researchers previously believed.
