Most extinctions are believed to occur as background extinctions because they result from gradual changes in environmental conditions, competition, and ecological shifts rather than catastrophic events. These slow processes allow species to gradually decline over time due to factors like habitat loss, climate change, and resource depletion. Background extinctions typically reflect the normal turnover of species, where weaker or less adaptable organisms are outcompeted or unable to survive in changing conditions. This contrasts with mass extinctions, which are sudden and dramatic, affecting a wide range of species simultaneously.
Sudden changes in environmental conditions.
Mass extinctions occur when extreme temperatures happen.https://science.howstuffworks.com/life/evolution/extinction3.htm

Well, there have been several "great extinctions" in earth's history, but the most recent one was the Cretaceous-Tertiary event, ending the Cretaceous. That was c. 65 million years ago.
invertabates are the animals with the most extinctions
Yes, extinctions have happened throughout history, they are happening today and will continue to happen in the future.
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct

Uniformitarianism: a principle stating that earths processes occurring today are similar to those that occur in the past

yeah its occurring in Darfur

No, they are fundamental to the process of evolution. Mass extinctions are less common.
The outcomes of each of the mass extinctions is that animal and/or bacteria die.
