Etymology
Neo-Darwinian combines neo- (meaning 'new') and Darwinian (from Darwin, the scientist who explained evolution), so it literally means a 'new' version of Darwin's ideas. That's why neo-Darwinian describes the modern form of Darwin's theory that adds knowledge about genes and how populations change.
