If some specimens are damaged or would otherwise not make good study skins or pelts, they often become complete skeletal preparations. During the course of preparation, the skeleton often comes apart and the bones are disassociated from each other. This is called a disarticulated skeleton, and is particularly useful when scientists need to study individual bones from an animal Check-list of California read for free In the shadow of Charles Darwin, young men who grew up collecting specimens and imagining their own museums came together to try to systematize their collections and professionalize their discipline Birds of Pakistan (Helm Field Guides) From work involving population genetics has come the realization, eloquently documented by two contemporary American evolutionists, Theodosius Dobzhansky and Ernst Mayer, that the species is the basic unit of evolution , cited: The Ibis: Journal of the read online Members were often involved in collaborative ornithological projects.
