Pronghorn Antelopes Are Well Adapted for Dry Conditions with Extremes

question 59

Multiple Choice

Pronghorn antelopes are well adapted for dry conditions with extremes of temperature, especially cold. As global climate change causes the region where the pronghorns live to change, in temperature as well as plant, predator, and prey diversity and abundance, what is likely to happen to the pronghorns?

• A) They will learn to eat whatever plants exist in their area and escape from any new predators that arrive.
• B) If the pronghorn population includes genetic variation that allows survival and reproduction in the new conditions, they will adapt.
• C) If climate change is not too rapid, the pronghorn can produce new traits needed to survive and reproduce in the changed conditions.
• D) Because pronghorns will need to be cooler, their fur will become thinner.
