The Society for the Study of Evolution was founded in March, 1946. The objectives of the Society for the Study of Evolution are the promotion of the study of organic evolution and the integration of the various fields of science concerned with evolution. The Society publishes the scientific journal Evolution and holds annual meetings in which scientific findings on evolutionary biology are presented and discussed.

The Ecological Society of America (ESA) is a nonpartisan, nonprofit organization of scientists founded in 1915 to:

• promote ecological science by improving communication among ecologists;
• raise the public's level of awareness of the importance of ecological science;
• increase the resources available for the conduct of ecological science; and
• ensure the appropriate use of ecological science in environmental decision making by enhancing communication between the ecological community and policy-makers

The Tree of Life Web Project (ToL) is a collaborative effort of biologists from around the world. On more than 5000 World Wide Web pages, the project provides information about the diversity of organisms on Earth, their evolutionary history (phylogeny), and characteristics.
