505 _aMendelism and evolution: Mutation and selection; genes and characters; the alteration of genic expression; the evolution of dominance; types of mutation; special cases: Melanism; polymorphism; fluctuating populations; mutation and evolution.
505 _aGenetic systems and evolution: The factors of evolution; the early evolution of genetic systems; the meiotic system and its adjustment; the consequences of polyploidy; species-hybridization and sex-determination: Conclusion.
505 _aThe species problem; geographical speciation: The biological reality of species; the different modes of speciation; successional species; geographical replacement: The nature of subspecies; clines character-gradients; spatial and ecological factors in geographical divergences; range-changes subsequent to geographical differentiation; the principles of geographical differentiation.
