Mutation Theory Experiments Observations Origin by Vries Hugo Translated Prof Farmer (1 results)

Hard Cover. Condition: Good. No Jacket. First Edition. Early evolutionary theory: De Vries points out that selection alone does not cause evolution - there must be variation from which to select. Here he discusses Darwin's and Wallace's theories, selection, acquired characteristics, mutation; origin of species in the genus oenothera; in volume 2, he discusses the origin of varieties within a species in plants. De Vries was unaware of Mendel's work until the late 1890s, rediscovering his theories in his own work, but barely mentioning him in these volumes. Two volume set, complete.
