This book is from 2008, so in terms of the science and its impact on the world, it’s a bit behind the times. It’s still a good primer on how the world was changing from a fairly monolithic view on genes to an understanding of the whole genome, “junk” DNA included, and it covers some worthwhile discussions. I found it a bit dry and pedantic at times, though it doesn’t help that the science was well below the level I understand now.
It’s most worth it when it focuses on the implications of the new genomics and the technologies involved. But I might be inclined to say skip it and look for something more modern if you’re not super interested.
