Cheetans have become an endangered species due to hunting and loss of their habitat. As a result,
there is now very little variation in the traits within their small populations. Which of the following is a result
of the limited variation in traits in today's cheetah population compared to earlier cheetah populations that
had greater variation in traits?
A. Cheetahs in current populations are more resistant to new diseases.
B. Cheetahs in current populations have better chances of survival today than they did in the past.
C. Cheetahs in current populations are less likely to become extinct.
D. Cheetahs in current populations are less likely to be able to adapt to environmental changes.
