How might extinctions affects the evolution of organisms that survive the event?
The role of mass extinction in evolution. At the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendent species they might have given rise to. ... But mass extinction can also play a creative role in evolution, stimulating the growth of other branches.

What type of event typically coincides with mass extinction?
Not entirely know, but obvious candidates are extrogenous events like a meteorite strike. Climate change via natural processes (eg Millankovitch cycles). There is also some that suggestion that mass extinctions may occur merely due to the fact that complex dynamic systems (like a global ecosystem) exihibits exitinctions events of varying magnitudes or fluctuations. Here mas extinctions are merely chain reaction of smaller extinction events as an individual species extinction (caused by small extrogeneos or introgeneous factors) cascades through an ecosystem. (See Self-organized criticality and punctuated Equilibrium.
What is a iatrogenic disease?
An iatrogenic condition is one that is caused by a doctor. A doctor-caused condition might arise, for example, from prescribing the wrong medicine or performing surgery improperly.
What was the outcomes of each of the mass extinctions?
The outcomes of each of the mass extinctions is that animal and/or bacteria die.
Large craters found on earth support the hypothesis that impact events have caused?
mass extinctions of animals and plants
Mass extinctions are usually followed by what?
When there are mass extinctions they are usually followed by adaptive radiation and very rapid diversification. The last mass extinctions happened 65 million years ago.
What has caused most of the mass extinctions on earth?
Mass extinctions are caused by rapid, global changes. Usually these are changes in climate. Without the right temperatures and precipitation, plants that animals depend on die out, which wipes out the animals. Examples include the Permian-Triassic Extinction, where volcanoes in what is now Siberia caused intense global warming, wiping out over 90% of species, and the K-T Extinction, where an asteroid impact suddenly blocked sunlight for months or years, killing off the dinosaurs and many other organisms.
What might have caused mass extinctions at the end of the paleozoic era?
the plants started to change and the herbavores started to die so the carnivivors had to kill each other and went almost extinct and then a meteorite shower finished them off.

Do scientists believe that extinctions are uncommon?
No, they are fundamental to the process of evolution. Mass extinctions are less common.
What has happened during mass extinctions?

Why mass extinctions occur and why they often mark divisions of geologic times?
Mass extinctions occur when extreme temperatures happen.https://science.howstuffworks.com/life/evolution/extinction3.htm
Why do you think most extinction's occur as background extinctions?
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
