This is not my first reading on seeds topic, because I have already read 'An orchard invisible' by Silvertown, which I have appreciated for its scientific rigor. I also appreciated Thor Hanson's book because, even if it is more colloquial, the author easily illustrates the most updated and modern theories concerning seeds. I only would have had notes and bibliography linked to the text, because I can't read again the text to understand the notes (or is it a problem of my Kindle edition?).
