Jared Diamond's central thesis in his bestselling book, Guns, Germs and Steel, is that the fate of human societies has always depended upon their skills as farmers ... This is what the plant sciences have always been about.
Plant sciences or botany! No biological science has transformed society more than the successive waves of agricultural revolutions - new ways of growing more food. It started with the domestication of cereal crops - wheat, rice and corn. And in the 20th century, the green revolution has allowed nearly 7 billion people to live on the planet. The story of botany leads from the founding of agriculture and medicinal plants to understanding plant physiology and reproduction to the founding of genetics to finally understanding the miracle of photosynthesis.
