What are adaptations?
Adaptations are changes in organisms that occur when they are confronted with changes in their environment.
What is an example of natural selection?
Peppered moths became more common in polluted areas as darker moths were better camouflaged against predators.
What is another example of natural selection?
Giraffes with longer necks could reach higher leaves, giving them a better chance of surviving.
What is migration?
Migration is the seasonal movement of animals from one region to another.
