Lynn Margulis

Lynn Margulis was a scientist who studied the evolution of cells. She proposed the theory of symbiogenesis, which states that eukaryotic cells (cells with a nucleus) evolved from the merger of two or more prokaryotic cells (cells without a nucleus).

Margulis was born in Chicago, Illinois, in 1938. She studied biology at the University of Chicago and then went on to get her PhD in genetics from the University of Wisconsin–Madison.

After graduating from Wisconsin, Margulis worked as a researcher at the University of Massachusetts Amherst. She published her theory of symbiogenesis in 1967, and it quickly became accepted by the scientific community.

Margulis's work has helped us to understand how life on Earth evolved. She is a role model for young scientists, especially girls and women.

Lynn Margulis was a pioneer in the field of evolutionary biology.
