This is the story of Lorena the gazelle, her pack, and how they experienced natural selection.
One thing that Lorena and her pack knew was they had to produce lots of offspring because it was the best chance that some of their fawns would survive. So the adults produced a total of 5 fawns which is an immense amount of fawns. They then left to go to their favorite water hole to rest.
The gazelle pack then left to go back to their home grassland. They realized that they had produced fawns with lots of variation; 2 of them had dark brown fur and 3 of them light brown fur increasing the chances of their survival because of variation. Unfortunately it was raining very hard and visibility was heavily reduced.
Unfortunately, during the midst of the heavy rain, a lion pack consisting of 3 males jumped about behind the hills they were hiding from and charged the innocent gazelles. Because of reduced visibility, the lions could only clearly see the dark brown gazelles. This resulted in all of the dark brown gazelles being caught and killed. They were the ones selected and eaten.
Lorena and the light brown gazelles were able to escape the lion attack and travelled to the river where they could rest and drink. They had survived but they had lost half of their population.
Then the remaining members of the pack went back to their favorite water hole in hopes of finding other gazelles and they were in luck. They found other straggling light brown gazelles who were able to produce offspring which passed down the favored light brown fur gene. This shows that the gazelles adapted to their harsh predators by keeping the light brown fur as the prominent gene.
