Extinction
* Every extinction corresponds to a death in the spirit of man
  - represents an irreversible loss of biodiversity
* Most extinction changes life.
* Most extinction decreases biological diversity
  - is caused by events
  - occurs during time
  - extinctions take place during the quiet, uneventful times , i.e. background extinctions
* Some extinction causes extinction.
* Some extinction is caused by activities
  - human activities
  - faced by chimpanzees
* also occur among ammonites, corals, and other invertebrates.
* are a good indicator of the health of the Earth.
* arises in both the land and the sea.
* can also be a force contributing to diversification
  - come about because of pollution
* can occur if a species is unable to adapt to a changing environment
  - in auditory and visual modalities
* causes damage.
* decreases biodiversity
* difficult event to detect, even in well known taxa such as mammals.
* function of oxygen consumption and metabolic rates.
* generally result from loss of habitat and encroachment by alien species.
* has big impact
  - cascade effects
  - large impact
  - nothing to do with the production of adaptation
* includes all processes which reduce the radiant intensity.
* involves eliminating any reinforcement that is maintaining a behavior.
* is actually a normal process in the course of evolution
  - also for species that are left without their necessary resources by others
  - annihilation
  - as much a part of evolution as death is of a part of life
  - books
* is caused by a variety of factors
  - alteration of a population's environment in a harmful way
  - both scattering and absorption of light by particles
  - conditioning
  - extremely common over geologic time
  - inaction
  - inversely proportional to wavelength so red light is less affected than blue light
* is one of the great mysteries of the geological record
  - way life on Earth can change
  - part of the process of evolution
  - terminations
* is the complete cessation of an inappropriate behavior
  - disappearance of a species from the earth
  - death of all members of a species
  - dimming of starlight as it travels through the dust
  - elimination of all individuals in a group
  - end of reproduction
  - flip-side of evolution
  - most serious, utterly irreversible effect of unsustainable human population
  - primary vehicle through which biological diversity is lost
  - process by which a group of taxa , normally a species , dies out
  - sum of actual absorption, and scattering
  - termination of evolutionary lineage
  - way traits leave a culture
  - what befalls the species that fails to adapt, to survive, to thrive
  - when a targeted behavior for modification or change stops
* loss to the biodiversity of an ecosystem.
* means being extinct or in the act of becoming extinct
  - more than the disappearance of species
  - no longer existing anywhere in the world, at least in the wild
* means that organism is gone from Earth forever
  - the unique values of the species are lost to the world forever
  - there are no living organisms of a certain species
* natural event that has happened since the beginning of time.
* natural feature of evolution
  - the evolution of life on Earth
* natural part of evolution
  - our planet's history
  - or the process of evolution
  - phenomenon, but rate of extinction drives biodiversity crisis
* natural process and normally takes place over many years
  - that has occurred through millennia
* natural process, a part of life
  - it happens all the time
  - occurs at some natural background level
  - result of evolution
* normal and natural process on the earth
* occur as a result of an inability to change.
* occurs when all members of species die out leaving no descendents
  - previous adaptations are no longer suitable to a changed environment
  - the natural rhythm of the Earth
* process that occurs over a long period.
* speaks to the disappearance of a defineable population.
* threatens many insect species along with other animals and plants.
* total waste of time.
* way to decrease rates of problem behavior.
+ Applied behavior analysis, Definitions and concepts, Extinction
  * Extinction is a way to decrease rates of problem behavior. Sometimes a problem behavior will be reinforced by accident. In order to fix accidental reinforcement the behavior has to be put through extinction. A problem behavior can only go through extinction if it has been reinforced before. To put a behavior through extinction the person must stop getting the reinforcement they want when they do the problem behavior. The problem behavior will decrease because the person will learn that this behavior no longer gets them what they want.
