What is Natural Selection?
Bon Voyage, Darwin!
The Same, But Different?
WHAT DOES IT ALL MEAN?
Darwin explains that all species of the planet have formed from a simple life form years before. Natural selection pretty much means that organisms that are best suited to their environment will have the ability to survive, reproduce and pass on the favourable traits on to the offspring.
HENCE, THE FINCHES BEING AN EXAMPLE OF NATURAL SELECTION! WOO!
Therefore, Darwin's finches allows us to see that there are favourable beak sizes and shapes to allow for the bird to find and eat a food source at each island.
One island may have a varity of fruits to eat, so a finch with a large, soft beak would have the characteristic to eat the fruits. Where a finch with a smaller, hard beak may have a better characteristic to pick seeds for the ground.
