Form and Function A Contribution to the History of Animal Morphology Is it accurate to speak of these animal groups as "crowds"? Introduction to the Science of Sociology We can see this illustrated most plainly in the animal group, where the male is the leader, by virtue of his strength. Sex and Society Many other illustrations of a similar change could be given, but the animal groups in which they occur being less familiar, the details would be less interesting, and perhaps hardly intelligible. Darwinism (1889) On the other hand, there is no reason for withholding the term "society" from many animal groups. Sociology and Modern Social Problems During his long and successful career as a purveyor of wild animals for all purposes, Carl Hagenbeck had great success in the production of large animal groups trained for stage performances. The Minds and Manners of Wild Animals A Book of Personal Observations In biology, isolation as a factor in the evolution and the life of the species, is studied from the standpoint of the animal group more than from that of the environment. Introduction to the Science of Sociology The idea which permeates Darwin's work is certainly one of real competition going on within each animal group for food, safety, and possibility of leaving an offspring. Mutual Aid; a factor of evolution These could only have arisen in animal groups in which the female did not rapidly flee from the male, but was inclined to accept his wooing from the first. Darwin and Modern Science In 1908 the most astounding animal group ever turned out of the Hagenbeck establishment, or shown on any stage, appeared in London.
