What it's about

In 1859 Charles Darwin published his theory that species aren't fixed but change over time through natural selection: individuals vary, more are born than can survive, and those best suited to their environment live to pass on their traits. He builds the case patiently, from pigeon breeding to fossils to the animals of remote islands.

Why it's worth reading

It's on the Guardian's list of the best nonfiction of all time and is one of the most important books ever written. It changed how humans understand life itself.

Good to know

It's written in Victorian prose, and the long sections on breeding and classification are slow. The first edition is shorter and clearer than later ones.
