life on a young planet sparknotes

Nicely written and well argued, especially in later chapters when the concept of "snowball Earth" reared its head. If I hadn't recently read several other books on both bacteria and the origins of multicellular life, I probably wouldn't have managed to finish it. But Knoll has a poetic sensibility (and a tendency to start out each section with a literary epigraph that warmed my heart). Microbes have evolved diverse mechanisms for surviving on a catastrophically evolving planet. After all, on planet Earth it took just a few hundred million years to create the first bacteria, but it took almost 3 billion years to create the first large creatures, like worms or trilobites. You need to have some geology vocabulary to have an easy-read, but that also helps to dive deeper into the topics and show a more nuanced discussion. It was definitely visible that the author has a vast knowledge in his field, and it was very interesting to read how he dissected different lines of arguments to draw conclusions. Use up and down arrows to review and enter to select. :) I felt like this was a solid read for my self-guided education on the history of the earth. Written by an expert in the field, with a whole professional life behind him, it's superbly, clearly and engagingly written - I haven't read a natural history book as good as this for a while. The Cambrian explosion some 543 million years ago, which marks a radical expansion of multicellular life-forms and the beginnings of the higher taxa known to us today, represents in fact a rather late episode in the history of evolution on our planet. Australopithecines, dinosaurs, trilobites--such fossils conjure up images of lost worlds filled with vanished organisms. Knoll deftly defeats this prejudice by pointing out that while animals are the kings of morphological variety, it is the microorganisms that are the exemplars of metabolism. Life finds a way. It is meticulously researched and a true source of knowledge. If a gas giant is found in a planet, the gas giant can give many characteristics to the planet. We owe our habitable planet (and its established biogeochemical cycles) to the metabolism of tiny living beings from long, long ago. Very well researched and presented. He describes the so-called evo-devo (I.e., evolutionary developmental biology) revolution with verve-both as an observer, and a participant/contributor. In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication. Knoll has a knack for writing understandable science and clearly explaining why scientists think what they think about early life and what evidence there is support or oppose a specific hypothesis. Refresh and try again. Most exoplanets are found through indirect methods: measuring the dimming of a star that happens to have a planet pass in front of it, called the transit method, or monitoring the spectrum of a star for the tell-tale signs of a planet pulling on its star and causing its light to subtly Doppler shift. .. expresses better than most the bumptious vitality and sheer fun of open-minded research.---Stefan Bengtson, Nature"Andrew Knoll, one of the world's foremost paleontologists, here presents the origin and early evolution of life the way it … YoungPlanet started as a family project and came about as a result of living and working in London, New York, Dallas, Paris, Istanbul and Moscow and entering new communities with young children. Just be ready to spend some time getting through this book, it can be difficult. An exceptional overview of the paleontological, biochemical and geochemical processes and mechanisms that made up our early Earth. Written by an expert in the field, with a whole professional life behind him, it's superbly, clearly and engagingly written - I haven't read a natural history book as good as this for a while. Other interesting topics include how periodic extinction events may have cleared the. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. Promoting a sustainable use of our ecosystems and preserving biodiversity is not a cause. He points out areas where more research is needed. I found this book listed as a top volume to read about the history of the beginning of the earth / life on our planet. As other reviewers have noted, be aware this is about life on the planet when it was just bacteria--there isn't much talk of animals, but that was fine with me--I wanted to know about the earliest of origins, befre humanoids. This book is all about discovering what life was like on the early earth - the first three billion years of evolution on earth (i.e. The study of the history of life on this planet has come a long way. It's a great read, fascinating, and very well written. Start by marking “Life on a Young Planet: The First Three Billion Years of Evolution on Earth” as Want to Read: Error rating book.

Black Beach A lawyer with a promising future is forced to deep dive into his past when he agrees to negotiate with an old friend turned kidnapper. Australopithecines, dinosaurs, trilobites--such fossils conjure up images of lost worlds filled with vanished organisms. I very rarely give 5/5 reviews, and then only to classics, but this is too good to receive four stars. Where Are You Going, Where Have You Been. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. It includes first hand details of the fieldwork and laboratory analyses carried out by himself and many others, and the evidence painstakingly gleaned, that underpin the latest theories in evolutionary sciences. It explains what early life was like and how it evolved. Considering it's mostly about slime--AKA bugs (prehistoric germs), algae, fungi, and these other weird things called archaea, you'd think it wouldn't have been so hard to put down. Goodreads helps you keep track of books you want to read. mostly precambrian). Knoll pulls it all together nicely in this well-written volume. Clearly explaining the theories and practices of the interdisciplinary sciences involved, this book is one of the best books on evolution I've read. This book focuses mostly on single-celled organisms. These could sterilize closely orbiting planets where life had only begun to get a toehold. Chemistry was my science of choice in college, but I hadn't really kept up in the interim, I found the more recent advances in our understanding of how early single-celled life developed and evolved and created the conditions for more complex life by modifying the atmosphere engrossing. A beautifully written book with numerous explanatory diagrams, B&W photographs and a section of colour plates. He has a great writing style and a quick sense of humor to get across his points about paleontology. In a nutshell - exceptional. The majority of the time life was on planet Earth (~3 billion years), it existed predominantly as single-celled organisms. David Attenborough: A Life on Our Planetis a 2020 British documentaryfilmnarrated by David Attenborough. The numerous charts, photographs, and diagrams are a huge plus. Fascinating book that starts when earth cools from its molten state and stops at the Cambrian Explosion . Welcome back. That means the vast majority of this book is about rocks, microbes and fossil microbes - with a bit of chemistry, earth science and comparative evolutionary biology to flesh things out. I found it hard to keep going at times -- in fact, I gave up once, then got it out of the library again -- although the author writes well and comes across as an appealing guide to geology and the paleontology of one-celled life. We’d love your help. The geological eon that is the focus of this book was a. The geological eon that is the focus of this book was a time when the world was alien, with at times relatively little oxygen, or covered almost to the equator in ice, or when the largest organism for staggeringly long periods of time was bacteria, a time that in some locations leaves abundant fossils, but are not a bone or a shell or carapace sticking out on a cliffside but microscopic ones, only able to be seen in a lab after preparation (though one learns on reading the book, towards the end there were definitely fossils that could easily be seen with the naked eye or even before the end if one knows what one is looking at such as with stromatolite fossils). But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Nevertheless, at some points it felt like I was reading something alond the lines of ''Dear Diary,....'' in the parts where he introduced his field work, which felt a bit boring and not as well written. An example of a planet that has gas giants would be Jupiter, Saturn, Uranus, and Neptune. Nevertheless, at some points it felt like I was reading something alond the lines of ''Dear Diary,....'' in the parts where he introduced his field work, which felt a bit. Thorough summaries and insightful critical analyses of classic and contemporary literature. A young girl discovers stories around her city by communicating directly with the ghosts who inhabit it.

Thing to keep in mind: The First Three Billion Years of Evolution on Earth sounds fascinating, but nothing much bigger than a microbacteria actually *evolved*. Life on a Young Planet . So when he asks that people heed … The detection of a gas in the planet’s atmosphere could turn scientists’ gaze to a planet long overlooked in the search for extraterrestrial life. Here, in this well-lighted cafe, the light is a manmade symbol of man's attempt to hold off the darkness — not permanently, but as late as possible. Andrew H. Knoll is a paleontologist who is particularly conversant with the integrative approaches of modern day evolutionary science. The author presents the research as a good scientist, with a healthy dose of skepticism, while basing conclusions on well established research. The stronger part of his conclusion reminded us that past may be prologue: That current action or inaction may have consequences in what could be, but doesn't have to be, our own evolutionary endgame. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. The origin of life. Needs a little basic understanding of middle school science to get through. There is an obligatory dramatisation of Attenborough as a … by Princeton University Press, Life on a Young Planet: The First Three Billion Years of Evolution on Earth (Princeton Science Library).

He explains the complex geochemistry that became, in time, a biochemistry. The Little Prince, fable and modern classic by French aviator and writer Antoine de Saint-Exupery that was published with his own illustrations in 1943. This was a good, readable (occasionally a little technical) popular science book on the early years of life on Earth, before abundant animal fossils started appearing it the fossil record, well before dinosaurs, before even trilobites, the most famous of Paleozoic marine fauna. From some ancient ancestor the three domains of cellular life emerged: prokaryotes (or bacteria), eukaryotes (cells with a membrane-bound nucleus), and the archaea, not recognized until 1977, and most commonly associated with life in the deep ocean thermal vents. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. This was a good, readable (occasionally a little technical) popular science book on the early years of life on Earth, before abundant animal fossils started appearing it the fossil record, well before dinosaurs, before even trilobites, the most famous of Paleozoic marine fauna. But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg.
