Even though Malthus was not a scientist, he was an economist and understood populations and how they grow. It was this key idea, that certain species would adapt to survive in the struggle for life, that led to Darwins development of evolution through natural selection. Malthus was the person who influenced Darwins idea that some offspring are better suited for survival than others.
