From my list of book reviews it will be blatantly obvious that I like non-fiction, especially non-fiction science books. I therefore naturally thought that The universe within by Neil Shubin would be a perfect match. A little bit of geology mixed with astronomy and evolution combined with reportedly good writing. It felt like a safe bet for me. I was wrong.
Shubin starts out by describing a geological expedition to Greenland. It was indeed interesting to learn about the hardships associated with finding stones that were formed during the time you are interested in. Shubin quickly moves on (it is a rather short book) to state that all living creatures on earth are related to one another and then he also takes it one step further, saying that we are also related to distant stars because had it not been for supernovas of massive stars the elements on which life depends, would not have formed. This, I suppose, is a profound fact, but I guess that a few paragraphs is not sufficient to convey a feeling of awe.
The book proceeds on a wild journey through space and evolution. Shubin writes about the origin of life and about the formation of stars as well as the entire universe. He frequently diverts from the main story (if there is one) and discusses other things such as the circadian rhythm. The part I personally found most interesting was the one about earth’s climate on a geological timescale. Did you know that before the Himalayas formed 40 million years ago (due to the collision of the Indian and Chinese landmasses), earth was considerably larger than it has been since then. At some points there were not even any ice caps over Antarctica. The Himalayas, Shubin explains, drained carbon dioxide from the atmosphere which was flushed into the oceans which in turn reduced the greenhouse effect of our atmosphere which cooled earth. We should expect more such drastic changes of the earth’s climate in the future and we better hope that we humans are able to adapt to such changes.
This is not a bad book but I feel that if suffers from trying to cover too broad an area in too few pages. It reminds me of when my supervisor was going to give a talk about “cognition and evolution”, which he felt was already stretching what you could cram into one talk. The arrangers however felt that this was too modest, can’t we change the title to cognition, evolution, and the cosmos to raise interest? I don’t know how that episode ended but I can imagine that, like this book, the result would lack focus.
