Most mountain hares have white fur because they rely on snow for protection in winter. Only a few hares have dark fur. Due to global warming, there has been a decrease in snowfall, and only rarely is there any snow on the ground. How do you think this might affect the population of mountain hares?

• They will all continue to have fur of a similar color

• With less snowfall, all white hares will die because they are now visible to predators.

• There will be more hares with dark fur because they will be less visible in their snow snow-free environment and will pass on their genes for dark fur to their offspring.

• All hares will migrate to a different area.
