Evolution of the Fox Population
Storyboard Text
- Natural Fox Population
- Life here is good!
- Change in Climate
- BRRR! Oh no, it's getting cold!!
- Survival Pressures
- OH NO! An eagle! I need to hide before it finds me!
- HAH! This eagle will NEVER find me...
- Two different species of fox live in the same habitat located in North America.
- Hunting for Prey
- The climate in North America changes from warm temperature to snowing and cold temperatures in the winter.
- Mating Reproduction
- During the winter, predators of foxes, such as an eagle, are able to spot dark-colored foxes better than light-color foxes, as white foxes are able to blend in with the snow during the winter.
- End Fox Population
- AWW! Look at all of our cute babies!
- The eagle was able to spot the brown fox easier than the white fox, therefore, brown foxes are eaten more often than white foxes. White foxes are able to escape being eaten by predators through camouflaging with the snow. As a result, the population of light-colored foxes decreases while the number of dark-colored foxes remain about the same.
- AHHH, he found me!
- Phew! I think I'm safe! The eagle can't tell the difference between me and the snow!
- The surviving fox population are able to mate and reproduce, therefore, passing on their traits.
- Glad we were able to escape that eagle! I love you!!
- I love you!
- Because less of the white fox population is hunted, more live to reproduce, therefore, passing on more traits to offspring. The white fox population continues to grow while the dark fox population is on the verge of extinction.
- I guess this is the end of our species...
