The key factors impacting species survival during environmental changes are previous adaptation, population size, and genetic diversity.
In a changing environment, the factor that has the most significant influence on the survival of a species is whether the species was well suited to its previous environment. Adaptations that helped the species thrive in its previous environment will determine its ability to survive and reproduce in the new conditions.
Number of individuals in the species also plays a crucial role, as a small population size can lead to genetic bottlenecks and reduce genetic diversity, making it harder for the species to adapt to new challenges.
Additionally, amount of diversity within the species provides a pool of genetic variants that may contain beneficial traits for coping with environmental changes, increasing the species' chances of survival.
