title: Evolution: pollen or pollinators - which came first?
abstract: A new study provides the first broad timeline of bee diversification. Several ancient bee clades are identified as ghost lineages that have left little fossil evidence of their existence. This timeline suggests that the rise of bees coincided with the largest flowering plant clade, the eudicots.
