Although Charles Darwin’s theory of evolution laid the foundations of modern biology, it did not tell the whole story. Most remarkably, The Origin of Species said very little about, of all things, the origins of species. Darwin and his modern successors have shown very convincingly how inherited variations are naturally selected, but they leave unanswered how variant organisms come to be in the first place.In Symbiotic Planet, renowned scientist Lynn Margulis shows that symbiosis, which simply means members of different species living in physical contact with each other, is crucial to the origins of evolutionary novelty. Ranging from bacteria, the smallest kinds of life, to the largest--the living Earth itself--Margulis explains the symbiotic origins of many of evolution’s most important innovations. The very cells we’re made of started as symbiotic unions of different kinds of bacteria. Sex--and its inevitable corollary, death--arose when failed attempts at cannibalism resulted in seasonally repeated mergers of some of our tiniest ancestors. Dry land became forested only after symbioses of algae and fungi evolved into plants. Since all living things are bathed by the same waters and atmosphere, all the inhabitants of Earth belong to a symbiotic union. Gaia, the finely tuned largest ecosystem of the Earth’s surface, is just symbiosis as seen from space. Along the way, Margulis describes her initiation into the world of science and the early steps in the present revolution in evolutionary biology; the importance of species classification for how we think about the living world; and the way "academic apartheid” can block scientific advancement. Written with enthusiasm and authority, this is a book that could change the way you view our living Earth. Keine Bibliotheksbeschreibungen gefunden. |

"In secret exercise of my perceived rights as a person of free will I snuck out of the University of Chicago eight-grade laboratory school, with its vastly inferior pool of potential boyfriends, and returned to the huge public high school where I had decided I belonged. I refused to stay another day in that lab school, where everything was so familiar and algebra was so hard. I was living in my parents' lovely South Shore Drive apartment and decided that running away was the only solution. Of course, I had no money, nowhere to go, and a rigid schedule of classes and duties."
Es kam wie es kommen mußte.
"Fury hit the fan when the high school administrators realized that my parents had no idea that I was not in the lab school; when I had told them that I was leaving I hadn't admitted that my parents didn't know. Of course my parents had not noticed the missing tuition bill. - Many teary sessions followed in and out of school."
Man bekommt aber einen Endruck, warum sich der charismatische Carl Sagan von dieser dickköpfigen jungen Dame angezogen gefühlt haben mag.
"At age fourteen I was lucky indeed to be accepted into the University of Chicago's special early entry program. Although three and a half years later I graduated with many acquisitions, including a liberal arts degree and a husband [Sagan], by far the most lasting was a thoroughgoing, finely nurtured critical scepticism. I cherish my University of Chicago education for its central teaching: one must always strive to distinguish bullshit from authenticity."
Obwohl das Buch nun schon ein paar Jahre alt ist (1998) bietet es einen immer noch aktuellen, allgemeinverständlichen, aber knapp gehaltenen (146 S.) Überblick sowohl über die Endosymbiontentheorie als auch über die Gaia-Hypothese. Ein klein wenig Grundwissen über beide Themen sollte man allerdings mitbringen. Der einzige Wermutstropfen ist die spärliche Ausstattung mit nur wenigen und durchgehend schwarzweißen Abbildungen. Beide, die serielle Endosymbiontentheorie (SET à la Margulis) und die Gaia-Hypothese, werden im Kontext ihrer historischen Entwicklung dargestellt. Insofern ist dies nicht nur ein Lehrbuch, sondern vielmehr ein Geschichtsbuch aus individueller Sicht – aber wie gesagt: man sollte sich wirklich für Biologiegeschichte interessieren.
Margulis ist von Grund auf Optimistin. Sie meint, die Erde wird auch mit so schädlichen Organismen wie Homo sapiens fertigwerden: "Gaia, a tough bitch, is not at all threatened by humans".
