Evolution and the Genetics of Populations, Volume 3: Experimental Results and Evolutionary Deductions is a foundational text by pioneering population geneticist Sewall Wright, part of his comprehensive four-volume treatise, focusing on how real-world data and experiments support population genetics theory, especially concerning species definition, population structure (F-statistics), gene flow, genetic drift, and adaptation. This volume offers detailed analysis of experimental findings to explain evolutionary mechanisms, including insights into his famous "shifting balance theory".

Species & Subspecies: Starts with defining species, a central concept in evolution.

Population Dynamics: Explores factors controlling population size and structure using F-statistics (measures of genetic differentiation).

Experimental Evidence: Presents data from nature and lab experiments to validate population genetics principles.

Evolutionary Mechanisms: Discusses how genetic drift, selection, gene flow, and the shifting balance theory drive adaptation and speciation.

Foundational Text: This is considered essential reading for evolutionary biology, synthesizing Wright's extensive work. It emphasizes experimental verification for evolutionary deductions, moving beyond pure theory.
