Fundamentals of plant genetics and breeding Book

This is a lovely book written about Darwin as a botanist. How his research on plants shaped his ideas about the world and helped him to develop the unifying theory of biology. It also covers much of Darwin's life story, including his voyage on the Beagle. I thought it was interesting and an enjoyable read. There are probably more definitive books on Darwin's life, but the botanical perspective gives this one a unique angle.
