It's happening right now. The human race has or is about to wipe out as many species as the meteorite that hit the planet 65 million years ago and ended the reign of the dinosaurs, which was about 90% of all life on earth.

∙ 12y agoThe world's largest mass extinction was the Permian-Triassic event about 250 million years ago, which wiped out 95% of earth's species. It marked the end of the Paleozoic era and the beginning of the Mesozoic.

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.
Mass extinctions create conditions that promote?
Adaptive Radiation
When did organisms suffer the largest mass extinction known?
The most devastating mass extinction occurred in the Late Permian (~250 million years ago).
What is it called in particular when a high percentage of the species on earth dies off at a particular time?
These are called "mass extinctions", and there have been five such events (that we know of) on the Earth. These are generally caused either by astronomical impact events (such as the asteroid that killed off the dinosaurs 65 million years ago) or massive volcanic activity. The causes of these extinctions has been a matter of some dispute, since they happened so long ago.
How mass extinction affected life on Earth?
Mass extinction isn't a natural role in any life-system. They happen as a consequence of some catatrosphic disaster or radical unbalance in the eco-system. As a result of mass extinctions other 'groups' evolve into species that take the place of those exterminated.
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.
The deadliest of all mass extinctions which killed 95 percent of all living organisms was the?
Permian-Triassic extinction, 251 MYA (million years ago) in the Paleozoic era.
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.
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?
Bad things
What affects have mass extinctions had on the history of life?
biospere
What might have caused mass extinctions?
Ice age
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
Mass extinctions create conditions that promote?
Adaptive Radiation
What has changed most of the mass extinctions on earth?
climate change
What have Mass extinctions determined?
order in which fossils are found in the fossil record.
