Question

How does mass extinction affect species that survive?

Answer 1

The mass extinction may cause the arrival of new species in the new and changing environment.

Further Explanation:

Mass extinction is the phenomenon when there is the extinction of many organisms or the group of an organism from the Earth due to change in environmental condition as it would not allow the survival of these organisms in the new environmental condition. This may cause the appearance of a new organism or the spread of mutant organisms in the prevailing environment that may play new roles. Hence new kind of ecosystem may be formed in the changing environment and those organisms that survive or get adapted to this condition may reproduce more and increase in number.

Therefore mass extinction although causes removal of some organism but may provide a new platform for the arrival of new kind of species and formation of a new ecosystem.

Answer 2

When there is a mass extinction, species that survive will combine gene pools. A gene pool is the sum of population of same species have the same genetic material. Those species that survived will combine for them to survive from extinction. If there is a combination of gene pool then there will be a possibility that evolution will happen
