Extinction event

endangered species? The Endangered Species Act was made so that our native plants, animals, and fish would not go into extinction. This Act requires that Federal and State agencies provide suitable conditions for endangered and threatened species, not to jeopardize from federal activities but to protect and save our native species from extinction. Throughout history there have been many events to lead up to this policy about the endangered species in the world. In 1901, Theodore “Teddy”…

Natural and Unnatural Causes of Wildlife Endangerment and Extinction Animal extinction is a huge epidemic that is happening faster than we ever expected. Endangered species are dying off left and right due to natural and unnatural causes. Things like poaching and global warming are constantly effecting our environment and changing the way species are living every day. All humans have a responsibility to take care of our environment, which, in turn, will help protect our species and others as…

brother gave me an idea. He brought up the concept of de-extinction, or bringing back animals from the dead, and human cloning. These ideologies, which used to be nothing more than the work of science…

Species Extinction: A Pathway to the Sixth Extinction We have all played a game of Jenga, each player removes one block per turn and either the tower will remain upright, or it will all tumble down. This Hasbro game is an exceptional example of the sixth extinction. Simply imagine each block as a different species. Humans are on top while other species like rhinos, polar bears and lions are on the bottom. If one is removed off of the bottom there is a possibility of all of them toppling over,…

have come a long way in terms of animal rights as a whole. It has protected many species from extinction, but what is left to be done? With factory farms and laboratory experiments it is time to find just what is left, and what has been done to help already. Extinction is in fact an ever-present force that looms over all life these past 540 million years. The primary cause of human-induced extinction events is simply human over population.…

Introduction: We are running an experiment using pigeons that will teach us about resurgence after extinction. Previous studies, such as Leitenberg et. al (Leitenberg et. al, 1970), have shown that it is possible for a behaviour that has been previously extinguished to have a sudden resurgence and become prevalent again. Podlesnik et. al, (Podlesnik et. al, 2006) attempted to re-create this experiment, and found the same results, the rats relapsed and returned to their previously extinct…

the condition are stimulus generalisation and discrimination, extinction and recovery. Generalisation is a type of condition where it promotes a similar response after the response has been learned. Secondly, discrimination is to break of the conditioned response with an other response it has not already been doubled with. Moreover, recovery is the bringing back of a response that has never really been forgotten and lastly the extinction involves the behaviour fading and decreasing away. Watson…

all examples of why we need Biodiversity. If I were to describe each and every dinosaur with one word it would be extinct. Why because they are all extinct. {Extinction is what happens when a taxon of organisms vanishes from the face of the Earth, meaning there is no more of that said species left, neither in the wild nor in captivity. Extinction occurs mainly due to the rapid changing of the environment. For example many species that lived and thrived during the Ice Age died off because of the…

I, B.F. Skinner, believe that the cause of abnormal behavior is not due to any psychoanalytical or biological cause, rather they are formed based on a person’s history of conditioning. Through my studies I have found that behaviors that bring about positive consequences have a greater likelihood of being repeated than behaviors that bring about negative consequences. This is known as operant conditioning, the shaping of behaviors by providing rewards to reinforce desired behaviors and…
