Quando nel 1967 la giovane biologa Lynn Margulis riuscì a pubblicare il suo primo importante articolo sull’origine delle cellule mitotiche venne sommersa da una marea di critiche, anche molto velenose. Non solo non si scoraggiò, ma continuò imperterrita a studiare il vasto e ignorato mondo dei microrganismi, convinta che in essi risiedesse la chiave dell’evoluzione del nostro pianeta e di tutte le forme di vita che lo abitano. Sostenne con caparbietà che la cooperazione, piuttosto che la competizione, costituisse il motore della selezione naturale e tolse alle mutazioni casuali il ruolo chiave nella speciazione. Gradualmente riuscì a dimostrare che tutte le cellule possono funzionare e dare origine a nuove specie grazie alla simbiosi con antichissimi batteri. Oggi, che la sua teoria rivoluzionaria è universalmente accettata e che, grazie alla microscopia elettronica e al sequenziamento del DNA, ha fatto fare un balzo in avanti alle teorie evolutive di Darwin, è più che mai opportuno che si conosca da vicino Lynn Margulis, una scienziata ribelle. [Abstract translated by Google Translate: This is the abstract in English… When in 1967 the young biologist Lynn Margulis managed to publish her first important article on the origin of mitotic cells, she was overwhelmed by a flood of criticism, even very poisonous. Not only was she not discouraged, but she continued undaunted to study the vast and ignored world of microorganisms, convinced that in them resided the key to the evolution of our planet and all forms of life that inhabit it. He stubbornly argued that cooperation, rather than competition, was the engine of natural selection and took away the key role in speciation from random mutations. Gradually he succeeded in demonstrating that all cells can function and give rise to new species thanks to the symbiosis with ancient bacteria. Today, that his revolutionary theory is universally accepted and that, thanks to electron microscopy and DNA sequencing, has made a leap forward in Darwin's theories of evolution, it is more appropriate than ever to get to know Lynn Margulis, a rebel scientist.]
