Strongly recommend you read Dawkins' "The Greatest Show on Earth" (https://www.amazon.com/Greatest-Show-Earth-Evidence-Evolutio...) and come back to tell us what you think :)

I have previously read the site kindly submitted for discussion today and have recommended it (here on Hacker News, too, as I recall) before. This site is well worth a read. A comment asks for a recommendation of a book about macroevolution, transformation to new species among descendant organisms, and I can not only recommend two books, but also a free website. The website is 29+ Evidences for Macroevolution,[1] which I have recommended often to readers here on Hacker News. The books are Why Evolution Is True by Jerry Coyne[2] and The Greatest Show on Earth by Richard Dawkins.[3] Both books are very readable and interesting and well deserve your attention. There are other good recent books about evolution that help fill in the research findings that have occurred since you or I finished our formal schooling.[4]

My favorite read in early 2009 was What Intelligence Tests Miss: The Psychology of Rational Thought by Keith Stanovich

http://www.amazon.com/What-Intelligence-Tests-Miss-Psycholog...

which is full of helpful information on developing the kind of cognition missed by IQ tests that constitutes rationality, very important information for parents, educators, and business leaders.

2009, the 200th anniversary of the birth of Charles Darwin and the 150th anniversary of the publication of his book On the Origin of Species, has been a banner year for new books on evolutionary biology. Some of my favorites include

Why Evolution is True by Jerry Coyne

http://www.amazon.com/Why-Evolution-True-Jerry-Coyne/dp/0670...

The Greatest Show on Earth: The Evidence for Evolution by Richard Dawkins

http://www.amazon.com/Greatest-Show-Earth-Evidence-Evolution...

and

Evolution: The First Four Billion Years edited by Michael Ruse and Joseph Travis.

http://www.amazon.com/Evolution-First-Four-Billion-Years/dp/...

All are full of up to date information about biology, which, as Thedosius Dobzhansky said, only makes sense in the light of evolution.

SuperFreakonomics by Steven D. Levitt and Stephen J. Dubner

http://www.amazon.com/SuperFreakonomics-Cooling-Patriotic-Pr...

is enjoyable and thought-provoking, sometimes laugh-out-loud funny, for all the usual reasons applying to collaborations by those two authors.
