The statement that most accurately describes evolution is:
**Evolution is the change in the genetic makeup of a population over time.**
This statement captures the essence of evolution as a process that encompasses various mechanisms, including natural selection, genetic drift, mutations, and gene flow, that can contribute to changes in a population's genetic composition over generations.

If an exotic zoo crossbreeds a tiger with a lion, it is performing **artificial selection**.
Artificial selection is the process by which humans breed specific plants or animals for desired traits, and in this case, the zoo is intentionally crossbreeding two different species (tigers and lions) to create hybrid offspring.

Rapid mass extinction may occur as a result of **a catastrophic event**.
Catastrophic events, such as asteroid impacts, volcanic eruptions, or significant climatic shifts, can lead to rapid and widespread loss of species. While the other options can contribute to declines in biodiversity, they typically do not cause mass extinction on the same scale and speed as catastrophic events.

A prolonged drought would likely **decrease the population size due to loss of habitat.**
Salamanders typically require moist environments for their survival, reproduction, and development. A prolonged drought would reduce the availability of water in the swamp, which can lead to loss of habitat and food sources, ultimately resulting in a decline in the salamander population.

According to kin selection, a chimpanzee will protect its **offspring** first.
Kin selection is a theory that suggests individuals are more likely to exhibit altruistic behavior towards their relatives (kin) because it increases the chances of shared genes being passed on to future generations. Protecting one's own offspring is a primary example of this behavior.

When developing his ideas about natural selection, Darwin focused most on **adaptations**.
Darwin's observations of the adaptations of organisms to their environments played a central role in his theory of natural selection, as he noted how these adaptations enhanced survival and reproductive success.

The best advantage that humans have today due to evolving during a period of significant environmental change is that **humans have a greater ability to adjust to change, so they can survive in a variety of environments and circumstances.**
This flexibility and adaptability stem from various factors, including intelligence, social structures, and technological innovations, allowing humans to thrive in diverse environments and face new challenges.

A likely consequence for walruses if the Arctic continues to warm at the current rate is that the **walrus population will decrease due to lack of suitable habitat.**
As Arctic ice melts due to warming temperatures, walruses lose their ice platforms, which are crucial for resting, breeding, and hunting. The reduction in ice can lead to increased competition for limited resources and may negatively impact their population.
