GENETIC BASIS OF DIFFERENCES IN GENITAL MORPHOLOGY AMONG THREE SIBLING SPECIES OF DROSOPHILA.

摘要: There is currently a debate about the relevance of microevolutionary studies to understanding macroevolutionary patterns. The classical view (e.g., Harland, 1936; Dobzhansky, 1970; Charlesworth et al., 1982) that phenomena such as adaptive radiation represent simple extrapolations processes which can be studied in field and laboratory. An alternative idea microand events have qualitatively different causes genetic underpinnings (Goldschmidt, 1933; Stanley, 1979; 1982; Gould, 1980; Vrba, 1980). Much controversy change during speciation. neo-Darwinian maintains basis phenotypic differences among populations individuals within species similar
