Evolution
⭐ MasteredOver many generations, living things change slowly. Those best suited to their environment survive and pass on their features. This is called natural selection.
Charles Darwin sailed to the Galapagos Islands and studied finches.
All about Evolution
Evolution is the slow change in living things over many generations. Individuals in a population differ slightly from each other. Those with features that help them survive and reproduce in their environment pass those features to their young.
This process is called natural selection. Over millions of years it has led to a huge variety of species, from tiny insects to giant whales. Giraffes with longer necks could reach more leaves, so they had more offspring.

Frequently asked questions about Evolution
Does evolution happen to individual animals?
No. An individual does not change its traits during its life. Evolution happens across generations in a population.
Did humans evolve from monkeys?
No. Humans and monkeys share a common ancestor that lived millions of years ago, and each species has evolved along its own path.
Is evolution a theory or a fact?
Evolution is supported by huge amounts of evidence from fossils, DNA and observations. The theory explains how it happens.
