Pollinator-driven evolution of floral traits is thought to be a major driver of angiosperm speciation and diversification.Ophrysorchids mimic female insects to lure male pollinators into pseudocopulation. This strategy, called sexual deception, is species-specific, thereby providing strong premating reprod...
Speciation is a central and fundamental process in evolution that concerns the origin of reproductive isolation. The latest generation of genomic approaches provide remarkable opportunities to describe speciation and to learn about its underlying mechanisms. Genome scans, which can now be carried out in ...

3), long after the origin of the last common ancestor of orchids (74–86 million years ago)13. Separate divergence analysis of the Copia and Gypsy TEs suggested that these two types of LTRs experienced a recent burst (Supplementary Fig. 3). Next, protein-coding gene models were constructed...
