Lynn Margulis

Sull'autore

Lynn Margulis was an influential American biologist, renowned for her groundbreaking work in the field of symbiotic relationships in evolution. She is best known for her endosymbiotic theory, which posits that certain organelles, such as mitochondria and chloroplasts, originated as independent prokaryotic organisms that entered into a symbiotic relationship with ancestral eukaryotic cells. This theory revolutionized the understanding of how complex life forms arose and has had a profound impact on evolutionary biology and microbiology.

Throughout her career, Margulis published numerous scientific papers and authored several books, contributing significantly to the discourse on evolution and the role of cooperation in biological systems. She challenged the traditional Darwinian view of evolution, emphasizing the importance of symbiosis as a key driver of biodiversity. Her work not only advanced scientific knowledge but also inspired a generation of biologists to explore the interconnectedness of life. Margulis's legacy continues to influence research in ecology and evolutionary theory today.
