Giraffe Natural Selection
This storyboard does not have a description.
Here there is a tall giraffe with a long neck and a short giraffe with a short neck.
The giraffe on the left is able to find food up in high places while giraffe with shorter necks have a disadvantage because they have to find the scarce food.
These giraffes eventually die out because of lack of food and resources.
Because all of the other short-necked giraffes died out, there are more long necked giraffe babies placed into the enviroment.
As the giraffes grew up they were able to get the food they needed and reproduce even more.
Because most giraffes live on this can cause overpopulation and lead to a different version of natural selection.
