This was a short, 89 page, simplified version of his book, “Replacing Darwin” (which I also own). I skimmed through the full version before deciding to read this one, because the full version is extremely technical (the author is a PhD), and frankly beyond me 😂 (though I may attempt it in the future anyway). This version is perfect for the layman, and I would recommend it to anyone who is interested in this subject as a very introductory book on the topic.
