Summary: Worthwhile reading for anyone of any generation
Review: One of my all-time favorites, I actually read this book with, of all people, my Grandmother, who was at least equally enchanted by it.The book is a fascinating account of the evolution of the human brain, and makes some powerful points about the ways in which our reptilian and other ancestors are still very much with us.

Summary: Evolutionary Thinking about the Brain
Review: Sagan certainly is a deep thinker and a thoughtful writer. However, as one would expect, this reviewer challenges the basic supposition of the work, that evolution is a scientific fact.
To many, his statement on pg. 6 is patently personal opinion, amply demostrated to be untenable, even in scientific circles: "Evolution is a fact amply demonstrated by the fossil record and by contemporary molecular biology. Natural selection is a successful theory devised to explain the fact of evolution."
There is no ample fossil record, and contemporary molecular biology itself provides reasonable doubts at to any evolution, e.g. Behe's "Darwin's Black Box." This is tragic when competent scientists such as Sagan change personal model choice of world origins into scientific fact. This cannot be demonstrated.
Even more recent evolutionists such as Gould agree. Jumping off this given, Sagan then speculates how the human brain has and is evolving. Much interesting and useful observations from inquiry into the human mind is good reading however. Taken with a filter of truth, this book provides for such a good read.

Summary: Carl Sagan makes you look at things differently.
Review: Sagan never lost his child-like wonder when describing the world around us. His writings are, for the most part, understandable and logical. We lost a great deal when he died, and I lost one of my favorite authors. A thought in one of his books stays with me: On a beach, pick up a handful of sand. You're holding roughly 2500 grains of sand, which is about how many stars you can see on a clear night. There are more stars in the universe than there are grains of sand on all the beaches in the world.

Summary: INSIGHTFUL
Review: Sagan once again does a wonderful job at allowing the average person to understand the more complex side of science. Get ready to really challenge what you think about the nobility of mankind.
Rating:
Summary: An early Sagan work still relevant today.
Review: Sagan's gifted style of writing manages to take difficult topics and present them in a readable, fascinating, and thought provoking manner. Sagan's works should be required reading in any high school science class.
