Lynn Margulis (Boston 1938 - ) is a biologist and Distinguished Professor at the University of Massachusetts.

Margulis holds a negative view of Neo-Darwinism. She formulated a theory to explain how symbiotic relationships that are taking place in modern-day humans and animals are the driving force of evolution. Margulis argues that inherited variation, significant in evolution, does not come mainly from random mutations. Rather new tissues, organs, and even new species evolve primarily through the long-lasting intimacy of strangers. The fusion of genomes in symbioses followed by natural selection, she suggests, leads to increasingly complex levels of individuality.[1]

Master from the University of Wisconsin (1960), Lynn Margulis received her Ph. D. in 1963 from UC Berkeley. She was elected to the National Academy of Sciences in 1983. In 1999, she was awarded the National Medal of Science.

Lynn was the first wife of American astronomer and astrobiologist Carl Sagan (Married in 1957). She also worked in Mexico at the Universidad de la Baja California.
