Evolution works better when groups of organisms of one species are separated from each other, whether by an ocean, desert or range of mountains. The separate groups evolve in different ways due to differences in environment, food availability or because of the preference of one sex liking or disliking certain traits in potential mate.
After a mass extinction the populations left of a single species may be few and widely dispersed. This would enhance the effect on many species of evolution by natural selection.

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 we think most extinctions occur as background extinctions?
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.
Why is it so important that the extinctions occurred soon after humans arrived on a new continent?
It is important because the timing suggests a strong correlation between human arrival and the extinctions, indicating that human activities likely played a significant role in driving these extinctions. This can provide valuable insights into the impact of human presence on ecosystems and the importance of conservation efforts to prevent future extinctions.
There will be a mass extinction in the cenozoic era?
There is no concrete evidence to suggest a mass extinction will occur in the Cenozoic era. Extinctions have happened throughout Earth's history, but predicting a mass event in a specific era is challenging. It is crucial to focus on conservation efforts to prevent any potential threats to biodiversity.
What type of weathering will occur more rapidly in an area with extremely cold winters and hot summers?
Freeze-thaw weathering will occur more rapidly in an area with extremely cold winters and hot summers. The repeated freezing and thawing of water in cracks and joints of rocks, caused by temperature fluctuations, can lead to the breakdown of rock material.

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

What is the animal group with the most extinctions?
invertabates are the animals with the most extinctions
How can an earthquake change the earths surface?
it can rapidly cause a landslide to occur

This can provide valuable insights into the impact of human presence on ecosystems and the importance of conservation efforts to prevent future extinctions.
Do scientists believe that extinctions are uncommon?
No, they are fundamental to the process of evolution. Mass extinctions are less common.
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.
What occur in the interphase?
The cell is metabolically active, synthesizing proteins, and growing rapidly

Do extinctions happen frequently?
No
Have extinctions occurred in the past?
Yes, extinctions have happened throughout history, they are happening today and will continue to happen in the future.
