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.
As the climate becomes cooler, species living in that region will need to adapt to the new conditions in order to survive. Some species may already have cold-weather adaptations, such as thick fur or hibernation, that will allow them to thrive in the cooler climate. Other species may undergo natural selection and develop new adaptations over time. However, species without the necessary adaptations may struggle to survive and could potentially go extinct. This process is part of the concept of biodiversity, where different species evolve and adapt to changing environments in order to maintain a healthy ecosystem.
