The Greatest Show On Earth by Richard Dawkins
Dawkins covers the difference between theory and “theory,” common descent, fossils, embryology, molecular evidence and the unintelligence of many “designs.” Although it was useful, informative and intermittently interesting, I did sometimes find it a bit dry and less compelling (likely because much of it was review). Alternatively, I quite enjoyed the final third of the book and consider it the best part. That is where Dawkins examined the many poorly designed parts of organisms and how all the evidence points to a process that generally adds upon and adapts existing structures instead of wholly replacing them (as it would be unlikely evolutionarily). In the final chapter, Dawkins takes the part of the final paragraph of On the Origin of Species and breaks it down and elaborates. I liked the idea and it was well executed.
It is a saddening thing that so many deny or are uninformed about the richness and beauty of both our natural world and the idea of evolution.
