Lynn Margulis began her scientific career very young and she will be remembered by her development of the role of the symbiosis as source of evolutionary innovation. Her pioneer works of the sixties favoured the progressive acceptance of the complex cells' origin from the reunion of simpler cells. The current evolutionary theory recognises and adds a major part the ideas that Margulis defended within the indifference when not the reject of most of the scientists of the age. Some of her other scientific contributions, result of an untiring and enthusiastic work until the same moment of its disappearance, have not being exempt of controversies either. An example was her contribution from the microbiology to the Gais hypothesis of James Lovelock.

In 2000, in the framework of the 5th centenary celebration of the University of Valencia, she made the American Geophysical Union to celebrate an international congress in the University. In 2001 she was invested ‘honoris causa’ doctor by the University of Valencia, later publishing a book that collects some of her most prominent contributions: Lynn Margulis, a revolution in the evolution (PUV, 2002). The Chair of Divulgation of Science has also edited, in Catalan and Spanish, the second edition of her Early Life. Margulis, that also collaborated with Mètode magazine, always recognised the esteem for the University of Valencia, and she showed a huge generosity towards her Valencian colleagues, who she visited several times, and she starred some of the most multitudinous academic and scientific acts now remembered.
