Definitely. As a total layman in this kind of stuff, I believe I’ve read The Selfish Gene first, but at the time I was so eager to consume as much knowledge as possible in this subject, that I could maybe be misremembering all the effort and research it took for me to understand it. It’s a fascinating book, but more specific.

Imo, Unweaving the Rainbow has a much broader appeal and is much easier reading. They’re both very different books.
