Organisms with a high degree of genetic variability and rapid reproduction rates are more likely to survive catastrophic environmental changes. This variability provides a better chance for some individuals in the population to possess traits that are suited to the new conditions and allow them to adapt and survive. Additionally, species with diverse ecological niches and broad ranges may also have a better chance of finding suitable habitats post-catastrophe.
Sudden changes in environmental conditions.
Organisms sensitive to changes in temperature and pH levels, such as coral reefs or certain fish species, would likely be harmed by the changes that occurred between those stages. These changes can disrupt their ecosystems and affect their ability to thrive and survive.
Estuaries would be a likely environment for marine organisms well adapted to drastic changes in salinity, as estuaries experience fluctuations in salinity levels due to the mixing of freshwater from rivers and saltwater from the ocean. Organisms in estuarine environments have developed physiological mechanisms to tolerate these changes.
Organisms with a broad ecological niche are more likely to survive than those with a narrow niche because they can adapt to a wider range of environmental conditions and have access to more resources. Organisms with a narrow ecological niche are more vulnerable to changes in their environment and are at higher risk of extinction.

Extinction is most likely to be caused by environmental conditions. Dramatic changes to the climate can mean that species are no longer adapted to survive.

Three changes are probably global temperature change(Ice Age,NOW), and...nothing else. This is most likely the only environmental change that affects evolution.
Environmental pressure refers to external factors that influence an organism's ability to survive and reproduce in its environment. These pressures can include changes in temperature, availability of resources, competition with other species, and predation. Organisms that are better adapted to these pressures are more likely to survive and pass on their traits to future generations.

The highest rate of natural selection would likely occur when organisms are under extreme environmental pressures, such as rapid changes in climate or competition for limited resources. In these conditions, individuals with traits that offer a survival advantage are more likely to reproduce and pass on their genes, leading to rapid changes in the population.
a greater chance to survive if the environmental conditions suddenly change.
Simple, single-celled organisms like prokaryotes, such as bacteria, likely developed first due to the early environmental conditions on Earth. These organisms were able to thrive in the primitive, harsh conditions of early Earth and played a significant role in shaping the planet's biosphere.
