What is the difference between evolution and natural selection?

Evolution is the change; natural selection is a cause.
Is evolution a theory or a fact?
It is both, in different senses. That living things have evolved and share common ancestry is an observed fact, supported by fossils, genetics, and direct observation. The theory of evolution is the well-tested scientific explanation of how that change happens. In science, a strong theory explains established facts.
What is an example of evolution?
A clear modern example is antibiotic resistance: bacteria that survive a drug pass on their resistance, so the population evolves to withstand it. Other examples include the peppered moth's colour shift during industrialisation and the varied beak shapes of Darwin's finches, each suited to a different food source.
Who developed the theory of evolution?
Charles Darwin is credited with the theory, set out in his 1859 book On the Origin of Species. Alfred Russel Wallace independently reached the same idea of natural selection around the same time. Later discoveries in genetics combined with Darwin's work to form the modern understanding of evolution.
