1. SOME SPECIES THAT ALREADY HAVE OR THAT DEVELOP COLD-WEATHER ADAPTATIONS THROUGH NATURAL SELECTION WILL SURVIVE, WHILE SPECIES WITHOUT COLD-WEATHER ADAPTATIONS MAY GO EXTINCT.
This is the most likely scenario as species that are able to adapt to the cooler climate through natural selection will have a better chance of survival, while species that are unable to adapt may go extinct. This process is a natural part of evolution and has been observed in response to changing climates throughout Earth's history.
SCIENCE: BIODIIVERSITY FINAL EXAM.
OVER TIME, THE CLIMATE OF A REGION BECOMES COOLER. HOW WILL THIS MOST LIKELY AFFECT THE SPECIES LIVING IN THAT REGION?
1. SOME SPECIES THAT ALREADY HAVE OR THAT DEVELOP COLD-WEATHER ADAPTATIONS THROUGH NATURAL SELECTION WILL SURVIVE, WHILE SPECIES WITHOUT COLD-WEATHER ADAPTATIONS MAY GO EXTINCT.
2. ALL OF THE CURRENT SPECIES LIVING IN THE AREA WILL BECOME EXTINCT, AND NEW SPECIES BETTER ADAPTED TO THE CLIMATE WILL FORM AND POPULATE THE REGION.
3. MOST OF THE CURRENT SPECIES LIVING IN THE AREA WILL DEVELOP BENEFICIAL MUTATIONS, WHICH WILL LEAD TO ADAPTATIONS THAT HELP SURVIVE IN THE NEW CLIMATE.
