WebDoes phylogeny build ontogenies, as Ernst Haeckel would have it, or do ontogenies make phylogeny, as Walter Garstang emphasized? Clearly, there is some relationship between ontogeny and phylogeny, since every change in phylogeny must result in changing ontogenies, while every change of ontogeny will cause a change in phylogeny.

WebPhylogeny—Ontogeny Parallels: A Trajectory for the General Acceptance of Operant Reinforcement? Natural Versus Artificial Selection In the first chapter of The Origin of Species, Darwin (1859/1958) made the distinction between artificial and natural selection. He referred to artificial selection as “selection by man.” Web“Ontogeny recapitulates phylogeny” was Haeckel’s answer—the wrong one—to the most vexing question of nineteenth-century biology: what is the relationship between individual development (ontogeny) and the evolution of species and lineages (phylogeny)? In this, the first major book on the subject in fifty years, Stephen Jay Gould documents the … Web4 ONTOGENY AND PHYLOGENY > Ontogeny and Phylogeny. By Stephen Jay Gould.
