I am sure genetics has advanced much since this book was written but I doubt that it's theories have been proven wrong. It is a well written, easy to read explaination of the molecular similarities between man, chimp and ape. And, using the molecular information, the authors propose an evolutionary tree that, to me, rings true.
Read this book.
The puzzle of the title is this: DNA studies show we share 95% of our genome with chimps. How can such a slight difference in our respective genetic blueprints account for such a huge difference in skull and brain anatomy?
This book proposes an explanation which, right or wrong, is just a splendid idea, a kind of intellectual marvel. The idea is that the brain is an ancient structure. It fully evolved over a period of many, many millions of years. This whole long evolutionary period is remote from us. It came and went a long, long time ago. In this scheme, the brain might, for example, have evolved within the head of an increasingly quick witted, deeply thoughtful, man-sized reptile. A big green one, let's say.
In subsequent evolution the structure of the big brain was lost. It went silent, unexpressed. But it rode the genome down through the eons until suddenly, just 2 million years ago, it was re-expressed in apes. Ourselves. A biochemical accident. Today, chimps still carry the silent code for a big brain, just as they (and we) carry the silent code for many ancient structures like gills and flippers. Chimps don't express DNA encoding the big brain, but we do.
If the hypothesis of an ancient big brain is accepted, a lot other problems suddenly solve themselves. The sudden, seemingly overnight appearance of the human brain, 2 million years ago, allows almost no time for such an elaborate structure to evolve. The answer: it didn't evolve 2 million years ago. It evolved long before, over a suitably long period of time, and simply re-appeared in man. Popped up fully realized.
A current book, The Prehistory of the Mind, by Steven Mithen, an archaeologist, emphasizes a fascinating observation. Although the big brain appeared 2 million years ago, mankind did nothing particularly intelligent or impressive until 1.9 million years later, that is, just 100,000 years ago. Man was a toolmaker, yes, but he kept making the same oafish, primitive tool, a stone axe, consisting of a rock tied to a stick, for nineteen hundred thousand years.
Finally, just 100K years ago, human beings suddenly got smart -he or more probably she -- finally found the boot disk.
Everything, the whole explosion of human progress, has happened since that day. An explanation of the long night of the human brain, per Gribbin's Monkey Puzzle, would be genetic drift. Lack of maintenance. An ancient brain would have come down us in very poor operating condition. DNA encoding for any feature that is unused over time will lose fidelity like a fading photograph. So it took 1.9 million years to get the biochemistry of the brain to start working right once again. Finally, 100,000 years ago, it happened to kick in. And the rest is history. Find this wonderful book.

the casual reader with an interest in particle physics. In "Q is
for Quantum" these amazing insights are presented in short,
succinct, manageable 'quanta'. Many of these statements and models
baffle, and read like the pronouncements of a first-century Gnostic on
how the universe and the fabric of reality are ordered. The difference
is that all these statements are buttressed by experiments and
mathematical models. Moreover, they are often ratified to a staggering
degree of accuracy.
How can we believe that reality is radically
altered by our observation of it? Even to the extent that our
observations of distant quasars today affect the way the light
emerged from them 10 billion years ago? How can particles be at two
places at once? How does every charged particle on the other side of
the Andromeda galaxy (2 million light years away) instantaneously
"know" if we poke an electron here on earth (see the entry
on "transactional interpretation")? I would suggest you read
the introduction to this book, and then the entry on "double-slit
experiment" and, as the author suggests, " ...follow your
nose from there." These shed light, albeit it a dim ray, on the
central mysteries of quantum mechanics.
John Gribbin's latest book "Q is for Quantum" is the perfect companion to his 1996 masterpiece "Companion to the Cosmos".
Gribbin's presents his work in a well illustrated, encyclopaedic (A to Z) style with nearly all topics having hyperlinks to cross-references elsewhere in the book. He puts great emphasis on the human dimension of science as well as on the purely physical phenomena and theories he describes so well. The mini-biographies of the scientists are fascinating in their own right, particularly when looking at the historical context and the geographic, social and academic connections/parallels that have led to these great advances in human thought.
Gribbin guides us along those amazing scientific paths of the past half millennia , from Galileo and Newton to Einstein and Hawking. He has this reader convinced that we are very close to realizing the ultimate dream of a Grand Unifying Theory (GUT) which ties together all the links between the forces of nature. His work is right up to date and includes the latest ideas on M-branes and superstrings.
The best way to read the book is to open it at random , find a topic of interest and see how far the hyperlinks can take you. Bliss for a net-head! The real strength of Gribbin's writing is to help us cover that great spectrum (in time and space) between the sub-atomic microworld of Quantum phenomena through to the edges of the Cosmos. Somewhere in the middle is the human dimension, dare I say, the "real world".
It was our friend Douglas Adams who posed that trickiest of tri-lemmas ... What is the answer to that ultimate question, that is, the Meaning of Life, the Universe and Everything ? He told us ... it is 42 !
John Gribbin's agrees - look up his section on Planck. What is the smallest unit of time? Answer: zero, decimal point, FOURTY TWO zeros, one second.
Before Planck time nothing much happened ... but then again ...

Gribbin fills in the background on that observation, describing how the simpler elements are formed during the big bang and how more complex elements are formed inside stars, particularly when they explode. It is a two-fold history, both of how astronomers and astrophysicists (a remarkably recent discipline) discovered how these were formed and of the universe itself and how it developed.
The only complaint I can come up with is that Gribbin gives Sagan too little credit, never quoting him with the statement above, even though it's truer and more characteristic than the "billions and billions" phrase the impressionists like to use. It's ironic that part of Gribbin's subtitle is the title of one of Sagan's most notable books.
Other than that, this is a gripping and easy-to-read relating of some of the fundamental concepts in modern astronomy. Highly recommended.
also, read 'river out of eden' by richard dawkins for information on human evolution.

"Hyperspace" takes the reader a a quest to find some answers as to how the universe and our galaxy was formed. This book is a companion to the TLC video "Hyperspace: Our Final Frontier." This book shows us how astronomers are now able to explore the universe by proxy... by light, radio waves, and x-rays. There is satellite information and revealing photography from the latest generation of astronomical telescopes all are here in the book making for some very interesting reading along with some interesting illustration to make a point.
The book's contents has but four chapters: Across the Universe, The Fate of the Universe, Making Contact, and Other Worlds. As you read the well-written narrative, you will learn about the universe and its wonders. This is an excellent text for understanding and learning about the universe without having an advanced degree.
