Using Miller’s hypothesis for adaptive evolution of thrashers(Toxostoma) from a mockingbird (Mimus) ancestor as representing thestandard evolutionary genetic model of the modern synthesis,explain how each of the following hypothesized processes ofevolutionary diversification differ: (1) West-Eberhard’s“alternative adaptations,†(2) West-Eberhard’s phenotypic andgenetic accommodation, and (3) McKay and Zink’s “Sisypheanevolution.†Include in part 2 a discussion of how geneticaccommodation resembles and differs from Waddington’s hypothesis ofgenetic assimilation.
