Evolution plays a big role in the different kinds of life on Earth. It happens through a few key processes: natural selection, mutations, and genetic drift.
Natural Selection: This is when species change to fit their surroundings. For example, the peppered moth learned to have darker colors to hide better in polluted areas.
Genetic Variation: Sometimes, small changes in an organism’s genes happen. These unique traits can help some individuals survive better than others.
Speciation: As time goes on, groups of a species can change so much that they become new species. A famous example is Darwin's finches from the Galápagos Islands.
These processes help create the amazing variety of life we see around us today!
