Genetic changes are like nature's toolbox. They help groups of living things adjust to new surroundings. Let’s break it down:
Mutations: These are random changes that happen in DNA. They can lead to new traits. For example, if a rabbit has a mutation that makes its fur darker, it can hide better in a shady forest.
Variation: When there are different traits in a group, some animals are better at surviving in certain situations. Think about a bunch of birds. Those with longer beaks can get food from deeper flowers.
Survival of the Fittest: The animals that have helpful traits are more likely to live longer and have babies. Those babies inherit the good traits from their parents.
In simple terms, genetic variation helps living things evolve. It allows species to do well even when the environment changes!
