Example Sentences

If the species originated by descent from the most closely related lower species, and under certain circumstances also from species of the same rank, and even by degeneration from the next higher, it must have occurred in one of two ways: either by leaps—called by naturalists "metamorphosis of germs" or "heterogenetic conception"—or by a succession of imperceptibly small alterations of the individuals from generation to generation.

From Project Gutenberg

The simple question of the origin of species led us into the dilemma of a generatio �quivoca, or a descent; the hypothesis of a descent led to the dilemma of a heterogenetic conception, or an evolution; and the hypothesis of an evolution rendered necessary the attempt at explaining this evolution, and showed Darwin's method of explaining it by his selection theory.

From Project Gutenberg

Many of these men are but little aware of the difference between the two questions: whether, on the one hand, the adoption of the origin of species through descent does not of itself involve the idea of a gradual development of one species from another, almost unobservable in its single steps; or, on the other hand, whether a descent of species through heterogenetic generation in leaps and through a metamorphosis of the germs, could be imagined.

From Project Gutenberg

Among them we find also scientists who answer the question in the sense of a new-modeling of the species, of a heterogenetic generation, and of a metamorphosis of germs.

From Project Gutenberg

Heer has introduced into scientific language the term "new-modeling of the species," K�lliker that of a "heterogenetic generation," and Baumg�rtner that of a "transmutation of the types through a metamorphosis of germs."
