Extinction is an evolutive process that leads to the disappearance of a species or a population. ... This process is known as speciation, in other words the birth of a new species. Speciation and extinction are both part of the natural evolutive process of living beings.

What is extinction and how is it achieved?
Extinction in psychology refers to the fading and disappearance of behavior that was previously learned by association with another event. That means a conditioned response is weakened and the target behavior eventually stops and becomes extinct. This is usually accomplished by withdrawing the unconditioned stimulus.
How do you explain extinction?
Extinction is the complete disappearance of a species from Earth. Species go extinct every year, but historically the average rate of extinction has been very slow with a few exceptions.
Is extinction is a natural process?
Extinction is a natural phenomenon: After all, more than 90 percent of all organisms that have ever lived on Earth aren't alive today. But humans have made it worse, accelerating natural extinction rates due to our role in habitat loss, climate change, invasive species, disease, overfishing, and hunting.
What is the process of extinction in psychology?
In psychology, extinction refers to the gradual weakening of a conditioned response that results in the behavior decreasing or disappearing. In other words, the conditioned behavior eventually stops. ... Eventually, the response becomes extinct, and your dog no longer displays the behavior.
What is extinction failure?
Extinction is a behavioral phenomenon observed in both operantly conditioned and classically conditioned behavior, which manifests itself by fading of non-reinforced conditioned response over time.
How do you explain extinction to a child?
Extinction is the dying out or disappearance of a species from earth. Remember, a species is a group of organisms that have common characteristics. Take the Tasmanian Tiger, for example. In 1986, it was declared extinct after the last remaining individual of its species died at a zoo in Tasmania.
What causes extinction?
Extinctions happen when a species dies out from cataclysmic events, evolutionary problems, or human interference. ... Humans also cause other species to become extinct by hunting, overharvesting, introducing invasive species to the wild, polluting, and changing wetlands and forests to croplands and urban areas.
What is true extinction?
True extinction, sometimes called species extinction or just “extinction”, involves either the loss of a species which existed in a single population instead of several, or the loss of all populations of a species to a larger causal event. Once an entire species is gone, there is no recovery.
What is extinction animals?
Extinct animals are animal species that have stopped breeding, died and no longer exist. The moment the last living species dies is understood as the time of its extinction.
What is extinction in learning?
Extinction learning refers to the gradual decrease in response to a conditioned stimulus that occurs when the stimulus is presented without reinforcement. ... During extinction, a new association with the stimulus is learned that inhibits the expression of the original fear memory.
What is extinction in biodiversity?
The biodiversity of an area is literally the number of species, both plant and animal, inhabiting the environment being examined. ... When a species is no longer found in a region, it is locally extinct. When it is no longer found anywhere, the species is considered extinct.
What are the 5 main causes of extinction?
There are five major causes of extinction: habitat loss, an introduced species, pollution, population growth, and overconsumption.
What are 4 man made factors leading to extinction?
Humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences.
