Description: (British Evolutionary Biologist Who Developed 'Lack's Principle')
David Lack was a prominent British evolutionary biologist who made significant contributions to ornithology, ecology, and ethology. His influential work on the Galapagos Islands finches, detailed in his book "Darwin's Finches," as well as other popular science books such as "Life of the Robin" and "Swifts in a Tower," solidified his reputation as a leading figure in the field. Lack's Principle, which he developed, revolutionized the understanding of avian clutch sizes by emphasizing individual selection over group selection. As the director of the Edward Grey Institute of Field Ornithology at the University of Oxford, he played a crucial role in advancing ornithology as a more research-focused discipline.
