Today class we are going to learn about natural selection
I can't find any fruit
Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring.
The first part of natural selection is the overpopulation of offspring. The monkey population is producing more monkeys than can survive to maturity. This also results in more competition for food.
I'm hungry! But I can't find any monkeys!
The next part of natural selection is variation. This is where we can see different characteristics in the monkey population. In this case its their fur color.
So that class is how natural selection works.
Then there is selection. This is when the best adapted monkeys are determined. These monkeys are the most likely to survive and reproduce. The smaller orange monkeys didn't blend into the trees so they were more visible to predators.
The last part of natural selection is adaptation. Since these monkeys are brown just like the tree trunks and branches they blend in.
