Question

Over time, the climate of a region becomes cooler. How will this most likely affect the species living in that region?(1 point)
Responses

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.
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.

All of the current species living in the region will migrate to warmer areas, while species adapted to cold-weather climates will migrate into the region.
All of the current species living in the region will migrate to warmer areas, while species adapted to cold-weather climates will migrate into the region.

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.
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.

Most of the current species living in the area will develop beneficial mutations, which will lead to adaptations that help them survive in the new climate.

Answer 1

The most likely outcome of a region's climate becoming cooler is the first response:

"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 statement accurately reflects the principles of natural selection, where species that can adapt to the changing environment (in this case, becoming cooler) are more likely to survive, while those unable to adapt may face extinction. The other responses describe scenarios that are less probable given the nuances of adaptation and species survival.
