Lynn Margulis (March 5, 1938 - November 22, 2011) was an influential American biologist and professor at the University of Massachusetts Amherst. She is best known for her groundbreaking theory on the origins of eukaryotic organelles, contributing significantly to the widely accepted Endosymbiotic Theory. This theory explains how certain organelles, like mitochondria and chloroplasts, evolved through symbiotic relationships between different species. Additionally, Margulis was associated with the Gaia Hypothesis, proposing that Earth’s living organisms and their environments form a self-regulating complex system essential for maintaining life.
