The exact reason for the Pleistocene extinction is still not known‚ this data implies that top-down forces and humans are the reason the extinction happened. This data is important because during the Anthropocene humans continue to put animals at risk for another extinction. The authors used data from the Pleistocene and recent data to show that high rates of predation and humans could have lead to the extinction. Both carnivores and humans caused the extinction‚ because both were competing for prey

GMO’s inside a lab and work to expel the uncontrolled production of GMOs‚ because of the fact that the genetically modified organisms can interact with the environment and cause the transfer of harmful genes which can lead to the elimination and extinction of all natural organisms.

Extinction is the ceasing of a species to exist on this Earth. A species officially becomes extinct when all of the species no longer exists. A species is to become certainly extinct when there is an extremely small number of it and it is unable to reproduce to create more of itself.

The argument refers to certain features that are present within the universe and within living organisms and where they possibly came from. Those who argue irreducible complexity say that these features are too complex to not have come from design‚ whereas those who argue against irreducible complexity say that it is possible for these complex features

instrumental (operant) conditioning they tend to immediately think of the "Skinner-Box". Skinner conducted classic experiments where he trained rats and pigeons to press a lever in order to obtain a food reward. The experimenter would choose a suited output to pair it with a consequence. After a training period‚ the animals would show the behavior (BH‚ e.g. pressing the lever) even in absence of any reward‚ if the BH-US association had been memorized. Instrumental conditioning differs from classical

Extinction is the end of an organism or group of taxa. Extinctions occur when a species becomes unfit for survival in its natural habitat usually to be replaced by another‚ better-suited species. An organism becomes ill-suited for survival because its environment is changed or because its relationship to other organisms is altered as stated from Credo Reference. The moment of extinction is generally considered to be the death of the last individual of that particular species. Mass extinctions‚ however
