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 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.
Who disappeared during the last mass extinction?
Notable extinctions during the last mass extinction included all non-avian dinosaurs, pterosaurs, plesiosaurs, and ammonites.
Do scientists believe that extinctions are uncommon?
No, they are fundamental to the process of evolution. Mass extinctions are less common.
Have extinctions occurred in the past?
Yes, extinctions have happened throughout history, they are happening today and will continue to happen in the future.
What affects have mass extinctions had on the history of life?
Mass extinctions have had a profound impact on the history of life by dramatically altering the diversity and composition of species. They have caused major shifts in ecosystems and have created opportunities for new species to evolve and adapt. Additionally, mass extinctions have played a key role in shaping the evolutionary trajectory of life on Earth.
What might have caused mass extinctions?
Mass extinctions can be caused by a variety of factors, including volcanic activity, asteroid impacts, climate change, and changes in sea levels. These events can disrupt ecosystems and lead to widespread loss of species.
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
The fossil record indicates that Earth has experienced?
5 mass extinctions
