Hybrid speciation in Heliconius butterflies? A review and critique of 
the evidence
Andrew V.Z. Brower
Genetica online first, DOI: 10.1007/s10709-010-9530-4

The evidence supporting the recent hypothesis of a homoploid hybrid 
origin for the butterfly species Heliconius heurippa is evaluated. 
Data from selective breeding experiments, mate-choice studies, and a 
wide variety of DNA markers are reviewed, and an alternative 
hypothesis for the origin of the species and its close relatives is 
proposed. A scenario of occasional red wing-pattern mutations in 
peripheral populations of Heliconius cydno with subsequent adaptive 
convergence towards sympatric mimicry rings involving H. melpomene 
and H. erato is offered as an alternative to the HHS hypothesis. 
Recent twists of this tale are addressed in a postscript.
