I found the degree of detail to fit well with the text's readability and I was uniformly impressed with the author's knowledge and presentation. Un incontro fatale - La nascita della cellula complessa. Sight was the surprise winner chapter for me. He then explains the chemistry which allowed life to escape its formative environment and the invention of the related processes of photosynthesis and respiration which have allowed life to flourish. Development of the complex cell, sight, power of movement and sex constitute a few of the characteristics identified by the author.
Fotosintesi e respirazione sono processi uguali e contrari. Chapter 10 - Death The diseases of old age appear to be tied to specific genes, suggesting that they are generally caused by a specific pathway. Life Ascending: The Ten Great Inventions of Evolution. Therapods show signs of the highly efficient breathing system possessed by the birds, which allows air to be passed over the lungs during both inhalation and exhalation. Gibi sıklıkla dile getirilen, bilimin açıklayamadığı düşünülen pek çok konu üzerine güncel tartışmalar hakkında muazzam bilgiler içeren bir kitap.
Birds acn extracted two or three times as much oxygen from rarefied air as can mammals. Ci sono due processi che introducono confusione negli alberi genici darwiniani: i trasferimenti laterali di geni e le fusioni di interi genomi. For example - there has been significant debate over whether life originated in 'black smokers' or alkaline vents mentioned earlier. Not as incestuous as it sounds. Ramybės būsenoje medžiagų apykaita vyks ne šiaip random lėtai, o 10 kartų lėčiau negu greičiausias to gyvūno medžiagų apykaitos variantas. In an engaging chapter on photosynthesis—as well as others dealing with the complex cell, the sense of sight and the emergence of sex and movement among organisms—Lane lays out processes of dizzying complexity in smooth, nimble prose.
It's a good thing I listened to the formless audiobook, or I'd have had a bonfire right then and there. This chapter is about how death works and how we can overcome it. Winner of the 2010 Royal Society Prize for science books Powerful new research methods are providing fresh and vivid insights into the makeup of life. While the octopus design seems to be more straightforward with the retina at the back, the human eye has better blood supply to the receptors allowing greater processing of the pigments. Throughout all the different chapters - Sex, Hot Blood, Death, Photosynthesis to name a few - you will learn in depth, the beauty of each of these systems and how and why they evolved, far more than just 'survival of the fittest' and 'selfish genes', but the chemical balances and trade off restrictions involved.
I do have to say that he'd have taken less flack for his discussion of consciousness if he'd made it the last part of a chapter on what are the current theories on the origin and history of the nervous system. Over the last decades, groundbreaking new research has provided vivid insights into the molecular makeup of life. It is possible that eyes triggered the entire Cambrian explosion, the point when most modern Phyla emerged. الفصل السادس الحركة تحدث عن الحركة كاختراع عظيم أسهم إسهاما عظيما في انتشار الحياة كما نراها الآن علي الكوكب. E senza la fotosintesi non esisterebbe nemmeno ossigeno libero. Dabar, deja, ši knyga man kelia frustraciją ir širdgėlą. Understanding evolution of eukaryote cells is difficult as lateral gene transfer and whole genome fusions cloud the gradual evolution processes.
Chapter 1 - The Origin of Life It appears that life started in the alkaline sea floor vents where seawater reacts with newly exposed rocks, creating the mineral serpentine. Get your mind out of the gutter! I love him because he blew my little mind. When the universe was a singularity -- when everything was contained in a space smaller than the period at the end of this sentence -- there was no time, no space, no matter, no beginning. If you pick this book up, heads-up : some sections of the book may seem overtly technical when they begin but if you continue on, the argument will be very clear soon enough. Why Energy Drives the Origin and Evolution of Life is expected in 2014. Ta prasme susidariusi per natūralią atranką? فيا لفصل التاسع تحدث عن الوعي، وفي الفصل العاشر والأخير تحدث عن الموت. Nick is a biochemist in the Department of Genetics, Evolution and Environment at University College London.
The reference to the paper by Freeland and Hurst opened up to me a whole set of articles of which I had not been aware before. However the book is more than just biochemistry, it is a run-down or rather run-up of 10 inventions of evolution that have had the greatest impact on the world, ranging from conditions in which the first proteins and genetic molecules were formed right up to consciousness and, surprisingly, death. He is the author of Life Ascending: The Ten Great Inventions of Evolution, which won the 2010 Royal Society Prize for Science Books, as well as Power, Sex, Suicide: Mitochondria and the Meaning of Life and Oxygen: The Molecule that Made the World. Lots of new things from recent and less recent research that I hadn't yet heard about, which was much of what I was hoping for from this book. He then worked as Medical Writer at for a year before joining Medi Cine International a medical multimedia company, also as a writer. I didn't need to worry about that with Dr. As we age, the mitochondrial populations wear out and the free radical leak creeps up.
He was awarded the 2015 Biochemical Society Award for his outstanding contribution to the molecular life sciences. Lane says that multicellular organisms have arisen independently five times, and lists red algae, green algae, plants, animals, and fungi. While relatively constant over recent time, the rate of carbon burial in the Carboniferous period lead to oxygen concentrations above 30%, allowing animals like dragonflies to become huge. But whatever our beliefs, this richness of understanding should be a cause for marvel and celebration. So, the problem addressed by Lane is the origin of the eukaryotic cell. With such high acclaim I approached Life Ascending with some enthusiasm, which was rapidly deflated when I found out Nick Lane is a biochemist — a field that has never exactly grabbed my imagination. Life Ascending won the 2010 Royal Society Prize for Science Books.
A thought provoking discussion on the meaning of consciousness and its physical significance is provided. This is science on the cutting edge, championing theories that have been gaining attention slowly in recent years, among those interested in biology but not in the mass media. Most of all though, I love that Lane shows us the process of science - the areas where things aren't settled, the places with scientists disagree, the ways that personalities can conflict with credibility. He did offer a book rec for further reading on the topic, Eating the Sun which, ha, my county library has and therefore so will I, shortly, so that's promising. I credit the computer, even more than the new scanning techs.
