Materials for the Study of Variation: Treated with Especial Regard to Discontinuity in the Origin of Species is a scientific book written by William Bateson in 1894. The book primarily focuses on the study of variation in species and how it can lead to the creation of new species. Bateson explores the concept of discontinuity in the origin of species, which refers to the idea that new species can arise suddenly and without a gradual transition from their parent species.The book is divided into two parts: the first part deals with the principles of variation and the second part focuses on the application of these principles to specific examples. Bateson uses a variety of examples from the animal and plant kingdoms to illustrate his points, including the study of domesticated animals, the variations in flower color in plants, and the differences between closely related species of birds.Throughout the book, Bateson emphasizes the importance of careful observation and experimentation in the study of variation. He also discusses the role of genetics in the creation of new species, although the field of genetics was not yet fully developed at the time of the book's publication.Overall, Materials for the Study of Variation is an important early work in the field of evolutionary biology and provides valuable insights into the study of variation and the origin of species.This Is A New Release Of The Original 1894 Edition.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
