Mass extinctions are usually followed by long periods of low or absent population. Some species always survive a mass extinction, following the Darwinian law of survival. When the dinosaurs died out the mammals began to prevail and eventually took over.

Mass extinctions are usually followed by what?
Mass extinctions are usually followed by a period of rapid diversification as surviving species adapt to new environmental conditions and fill ecological niches left vacant by extinct species. This diversification can lead to the emergence of new species and ecosystems over time.
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.
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
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
The fossil record shows that periods of what are followed by diversity in organisms?
The fossil record shows that periods of mass extinctions are followed by bursts of diversity in organisms. This phenomenon is known as adaptive radiation, where surviving species rapidly diversify to fill empty ecological niches left by the extinct species.
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.
The fossil record indicates that Earth has experienced?
5 mass extinctions
The fossil record shows that periods of blank are followed by diversity in organism?
The fossil record shows that periods of extinction are followed by bursts of diversity as new species evolve to fill vacant ecological niches. This pattern is known as adaptive radiation.
