Natural Selection in Squirrels
Overproduction of Offspring
A squirrel population has to learn to survive through all of the seasons, and their bodies must learn to adapt to predators and the seasons.
These squirrels know that soon it will be time to grow their population, so they can survive through natural selection.
Selection Part 2
Squirrels usually produce 5-6 younger squirrels, and they vary in color, because of the mix in genetics.
Little do they know, there is an owl lurking above looking to come in for the kill.
The hungry owl is quick to see something red, not blending in on the ground. While it is necessary to have variation in a species, the squirrels are now easier to see, so they will be hunted.
Because their population was getting killed off, over time the red squirrels start to disappear, therefore they are not passing down the genes for red fur. The brown fur color starts to become more prominent in the species.
