what do scientists think caused the permian mass extinction? The scientific consensus is that the causes of extinction were elevated temperatures and in the marine realm widespread oceanic anoxia and ocean acidification due to the large amounts of carbon dioxide that were emitted by the eruption of the Siberian Traps.

Why did modern humans outlive Neanderthals? In the great saga of evolution, humans survived and Neanderthals didn’t. New research suggests why. Humans (Homo sapiens) may have caused the extinction of Neanderthals (Homo neanderthalensis) because of our greater talent for social innovation and tool creation.
Is the vaquita doomed? The vaquita—a wide-eyed porpoise whose mouth rests in a beckoning smile—has long been teetering on the edge of extinction, its small habitat besieged by illegal fishing. Now a change to Mexican regulations appears to spell the species’ doom.

Why should we protect penguins?
Marine reserves: The creation of large-scale, fully protected marine reserves can serve to alleviate pressure on penguins in the face of climate change, overfishing, and habitat degradation. Although marine reserves do not stop climate change, they can help keep ecosystems resilient and food webs intact.

Resistance to extinction refers to the amount of responding by an individual after reinforcement has been removed. Intermittent schedules of reinforcement, thinner schedules and variable schedules are associated with a greater resistance to extinction.

Extinction occurs when species are diminished because of environmental forces such as habitat fragmentation, climate change, natural disaster, overexploitation by humans, and pollution, or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
What is it called when an extinct animal is found?
