Biography

Lynn Margulis was a pioneering American evolutionary biologist, best known for her theory on the origin of eukaryotic organelles and her contributions to the endosymbiotic theory. Born in Chicago, Illinois, she showed an early interest in biology, earning her Bachelor’s degree from the University of Chicago, her Master’s degree from the University of Wisconsin, and her Ph.D. from the University of California, Berkeley. Margulis spent much of her career at the University of Massachusetts Amherst, where she was a distinguished professor. Margulis’s groundbreaking work suggested that key organelles in eukaryotic cells, such as mitochondria and chloroplasts, originated from symbiotic relationships between separate single-celled organisms. Initially met with skepticism, her theories eventually gained wide acceptance and significantly influenced our understanding of evolution and cell biology. In addition to her scientific contributions, Margulis was an outspoken critic of the neo-Darwinian emphasis on competition, instead highlighting the importance of cooperation and symbiosis in evolution. She authored numerous books and scientific papers, and her work continues to inspire biologists around the world.
