Speciation challenges the meaning of "beneficial mutation"

... variation and hyrbid viability, and how this gives a new perspective on speciation. I am a GED-holding college student. The biological species concept defines species as unable to produce viable hybrids. Hybrid viability brings into question the typical notion of an allele as beneficial ...
