A-posteriori comparisons are shown in Figure 3. years. These criticisms are in two forms. First, the assign- ment of specific evolutionary mechanisms to phenotypic divergence has been questioned on the logical grounds that most investigators postulating such mechanisms did not properly test alternative hypotheses (Connell, 1980; Underwood, 1990; but see Roughgarden, 1983). The sec- ond criticism has been directed at investigators who failed to consider genetic constraints when proposing evolu- tionary explanations for ecological data (Gould and Lewontin, 1979: Lande, 1979, 1982; Templeton. 1981; Lynch, 1984). For an examination of phenotypic diver- gence of an isolated population in a novel environment, like Balanm amp/iilritc in the Salton Sea, understanding these criticisms is crucial because phenotypic modification of individuals in the novel environment is the expected result of either evolutionary or plastic processes (see End- ler, 1986).
