What else can I help you with?
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.
The earliest molusks?
Have desendants that survived several mass extinctions Most likely had a single flattened shell Likely had the gills and anus located posteriorly while the mouth and nerve ring were located anteriorly
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 earliest mollusks?
Have descendants that survived several mass extinctions Most likely had a single flattened shell Likely had the gills and anus located posteriorly while the mouth and nerve ring were located anteriorly Yes it is all of these
Mass extinctions create conditions that promote?
Adaptive Radiation
What has changed most of the mass extinctions on earth?
climate change
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.
Which of the following statements best describe the current scientific view of birds?
A group of feathered, endothermic dinosaurs that survived the Cretaceous mass extinction.
Names of dinosaurs that survived extinction?
No dinosaur species survived the mass extinction event that occurred at the end of the Cretaceous period about 66 million years ago. However, birds are considered descendants of theropod dinosaurs and are the only living group of dinosaurs today.
