"On Methuselah's Trail" is one of the best books I have read about fossils and evolution. Not revolutionary, challenging or very complicated - just well written, charming, and - most important - it makes you want go right out in the bush to look for your own fossils!A Wonderful Book! I wish this book had been around when I was in high school because it brought the field of science in general, and geology/biology in particular, alive for the first time. I honestly looked at my natural surroundings differently after reading it. I have also purchased and enjoyed the hard cover copies of Professor Ward's other two books. Some of the passages he writes especially with regard to bringing you back in time give you shivers.
