Longevity extension of worker honey bees (Apis mellifera) by royal jelly: optimal dose and active ingredient.

abstract：:Parallelism is important because it reveals how inherently stochastic adaptation is. Even as we come to better understand evolutionary forces, stochasticity limits how well we can predict evolutionary outcomes. Here we sought to quantify parallelism and some of its underlying causes by adapting a bacteriophage (ID11) ...
