Most people in the western world used to have a solid idea about our origins: all living organisms were deliberately formed by a single creator. Then, in 1831, a 22-year-old student decided to go on an expedition that would change everything. Upon returning home Darwin came up with his theory of natural selection — a process through which living organisms adapt, reproduce and change. The evolution of peppered moths in the United Kingdom during the industrial revolution is a great example of this process.
