A little pot stirring here.

Mixing "facts", perceived wisdom, old wives tales, science and a bit of c=heek
we have:-

Hybrids have characteristics of both parents, they are more vigorous (hyb=rid
vigour) and should tolerate a wider range of conditions than either paren=t.

Hybrids are sterile (well sometimes) and can come true from seed or produ=ce
progeny of morphology anywhere between either parent.

Evolution (if you believe in it) produces new species better able to "tak=e
over" an available niche or environment than their ancestors.

Putting all this together, perhaps some of the "hybrids" which form such
narrow bands between two species (Trillium or Erythronium) are actually r=elics
of the ancestor or both species.

Logic - they are clearly "unsuccessful" compared to the more "evolved"
species, they are often fertile and can breed with both "new" species, th=ey
have all of the required genes to evolve into both new species.

Proof is easy, just sequence mitochondrial DNA of all three and count
mutations, the more mutations, the longer ago the species separated from =a
common ancestor.   If the hybrids are recent they are hybrids, if they ar=e
older then they are ancestors.

Any takers?   It might help to pass the 12 months while Red Berries sorts=out.
