There is a population of Galapagos finches living in the island.
Some fiches have higher chance of surviving while other have low chances of surviving because of their appearance.
Some stay on Grassy land while some stay in near the ocean
Geographic Isolation is where 2 populations of the same species where are separated by a geographical barrier.
Variation is the differences in traits and physical features in a population
Some Finches are bigger while other are smaller.
Selection is where some organisms have traits that give higher chances of survival and reproduction
The offspring inherit the traits of their parents like their color and appearance.
Inheritance the process of when a fit organism that survives reproduces and passes down traits which their offspring will inherit.
When the finches meet again, they are a completely different species as the ones by grassy land are smaller whereas the ones by coast have different traits that are suited for the environment.
Time is the important factor as over time certain traits that are helpful to an animal's habitat become more popular
