There are about Anyway, Gould repeated and repeated and repeated the same conclusions over and over and over and over, until I was ready to embrace the iconographies of the cone of increasing diversity and the ladder of progress just to spite him.

But the animals of the Burgess Shale are weird and amazing and beautiful in their own way, and stephe principles of design are far more imaginative than anything I’ve ever read or seen in science fiction. Since clades are monophyletic all descended from a single common ancestorthere is always going to be a “cone of increasing diversity”, because the clade always depicts hierarchical branching lineages of descent.

But Gould has an unique talent of de This is a pinnacle in popular science writing. I found the writing style to be quite dry and technical. To be fair, that IS the subject of the book, but it’s a subject that could perhaps have been elucidated with fewer pages of grandstanding and petty squabbling with the scientific establishment.

Some 80 percent of all named animal species are arthropods, the vast majority insects. When some fish developed forearm like fins it was for use in water not to colonize land. His respect for the reader as an ‘intelligent layperson’ is refreshing and makes this book a real pleasure to read. He points out that mammals lived alongside dinosaurs for million years before the Cretaceous-Tertiary extinction.

And his passionate commitment to the notion of an intelligent lay audience that he can explain them to. Unfortunately, most of the book is out of date. He gets all worked up about subjects that don’t really bother me. Many were formed by soft bodied creatures never before known.

oa Gould calls these animals with their diverse anatomies “weird wonders” and explains that their broad proliferation was possible because the middle Cambrian was a time of filling the so-called “ecological barrel. If your curiosity about the Burgess Shale or the weird and wonderful beings of the Cambrian period needs sating, this book should more than do it.

From the outset the author’s bias for his subject is apparent. Four such papers appeared in and see Bibliography —the first on arthropods that he considered incorrectly as related to horseshoe crabs, the second on maravillosq and jellyfish probably all attributed to the wrong phylathe third on worms, and the fourth and longest on arthropods.

He never again published a major work on Burgess metazoans. East Dane Designer Men’s Fashion. Learn more about Amazon Prime. Once, it was thought that these animals were only simpler versions of modern animals, however, extended study of these animals found the animals to be several times more diverse than any faunal assemblage today.

I am very much impressed by him. An Urchin in the Storm. For example, in Haeckel’s illustrations, Gould does not analyze the taxonomic groups represented, nor does he consider that Haeckel perhaps wanted to show the phylogenies of the taxa he placed close to the top, and thus gave them more visual importance, because, after all, there is only so much space on the page.

Wonderful Life: The Burgess Shale and the Nature of History

The only critique I have against the book that it beats a dead horse on the effect of contingency in the evolution of life a bit too much; but mqravillosa in the era it was written it was not that obvious. Those Burgess Shale lifeforms that have modern day progeny were lucky. Science, like farming, is hard work. The single real takeaway from the book mwravillosa the idea that life had the highest degree of morphological diversity at the inception of multicellular life and has since only decreased in anatomical diversity not to be confused with the increase in speciation over time.

If you know what a “chelicerate arthropod” is, then dive right in! The ultimate maravilolsa of the book is still being debated among evolutionary biologists today.

I was interested to see that I didn’t hold some of the preconceptions he argues against – I hope because this book is rather out of date, being ivda in the year I was born! Gould regarded Opabinia —an odd creature with five eyes and frontal nozzle—as so important to understanding the Cambrian explosion that he wanted to call his book Homage to Opabinia.

This is an account worth reading of the recollections of ploughing. So, once I calmed down a bit, I conceded that perhaps Knight influenced more imaginations than Kish. In the late 60s Harry Whittington began to study the Burgess fossils in detail and discovered that many of them beloned to lineages which left no modern descendants. My passion for fantasy and science fiction followed later, during my teenage years. A fascinating story, with Gould’s analysis at the forefront. He explicitly states over and over that this material is a revolution, that it overturns the establishment, and that it’s an incredible drama.

A beach from the Silurian Period, still not entirely turned to rock. Also gives a nice biography of Walcott, the man who discovered the Burgess Shale. Anyone who has visited the Smithsonian Museum of Natural History in Washington DC has probably seen the gorgeous murals of ancient life under the sea, done by Eleanor Kish.

So he talks about how Charles Doolittle Walcott marabillosa everything wrong except for the na I’m not saying anything startling or new when I say this book is awesome.

Jan 03, Max rated it really liked it Shelves: Another thing learned from the Burgess Shale is the imprecision of the concept “survival of the fittest. Most of the “weird wonders” that Gould describes have been taxonomically re-evaluated in the previous two decades, and technical developments in systematics the concept of “stem groups” in cladogramsnow show that much Burgess biota, vid, belong closer to the original classifications of Walcott.

I will however say that, as enchanting as I found this book, if you aren’t interested in analyses of middle Cambrian fauna, this is probably not the book for you.
