How might extinctions affects the evolution of organisms that survive the event?
The role of mass extinction in evolution. At the most basic level, mass extinctions reduce diversity by killing off specific lineages, and with them, any descendent species they might have given rise to. ... But mass extinction can also play a creative role in evolution, stimulating the growth of other branches.
What might have caused mass extinctions?
Ice age

What influences the kinetic energy of an object?
The mass and velocity of an object determine the kinetic energy of an object. The equation for kinetic energy is KE = 1/2mv2, where m is mass in kg, and v is velocity in m/s.
What type of event typically coincides with mass extinction?
Not entirely know, but obvious candidates are extrogenous events like a meteorite strike. Climate change via natural processes (eg Millankovitch cycles). There is also some that suggestion that mass extinctions may occur merely due to the fact that complex dynamic systems (like a global ecosystem) exihibits exitinctions events of varying magnitudes or fluctuations. Here mas extinctions are merely chain reaction of smaller extinction events as an individual species extinction (caused by small extrogeneos or introgeneous factors) cascades through an ecosystem. (See Self-organized criticality and punctuated Equilibrium.
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
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 effects mass extinctions had on the history of life?
The largest mass extinction in the history of the earth could have been triggered off by giant salt lakes, whose emissions of halogenated gases changed the atmospheric composition so dramatically that vegetation was irretrievably damaged.
Climate changes have been linked to almost all mass extinctions of life on Earth?
true
What mass extinctions in the tertiary period?
it killed 99.9999999999999991% of the worlds life including plants and mammals
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 effects have mass extinctions had on history life?
Mass extinctions have the effect of eliminating a large number of species, which leaves a wide variety of niches open to new species. Whichever species survive the mass extinction quickly evolve into many new forms to fill the empty niches. The Permian-Triassic Extinction Event left niches open to the dinosaurs, and the Cretaceous-Tertiary Extinction eliminated dinosaurs, leaving niches open to mammals.
What has happened during mass extinctions?
Bad things
What might have caused mass extinctions?
Ice age
