Adaptive radiation: evolution of numerous species from a common ancestor.
Biodiversity: diversity of living organisms. Biotas: assemblages of organisms. Biotic: from living organisms.
Darwinian selection: selection of organisms based on the relative contribution of an organism to the gene pool of the next generation.
Ecospace: area available for organisms to occupy. This is partly a physical space, and partly a series of interactions between organisms.
Evolution: processes of change in living organisms over time. Niche: the sum of an organism's use of all available environmental resources. Also called an ecological niche. Species: organisms with similar anatomical characteristics that can, potentially, interbreed.
Species diversity: number and relative abundance of species in a biological community.
Taxonomy: science of naming and classifying organisms.

This is common knowledge that disaster is everywhere. Its in the streets, its inside your campuses, and it can even be found inside your home. The question is not whether we are safe because no one is really THAT secure anymore but whether we can do something to lessen the odds of ever becoming a victim.
