There are 3 types of polar bears: ones with thick coats, ones with thin
coats and ones with medium coats. It is fall, soon to be winter. The
temperatures are dropping rapidly and the bears must be kept warm,
or they will freeze to death. Many of the bears have had ~2 cubs each
but due to the extreme temperatures, many mothers only have one cub left.
1. What is the favorable variation for Natural Selection in this scenario?___________________________
2. Darwin says every population has variations. What are the variations in this population?
___________________________________________________________________________________
3. What evidence shows that this population produces more offspring than can survive?
__________________________________________________________________________________
4. What will happen to the bears with the favorable variation?
__________________________________________________________________________________
5. Over time, how will this population change because of Natural Selection?
