Lynn Margulis

She was a biologist. Biology is the work that studies life and living organisms. Some of the other things studied in the field of biology are structure, growth, function and evolution.
Lynn Margulis was born on August fifth 1938.
She died on November 22nd 2011 in Amherst Mass.
Place of Birth
Lynn Margulis was born in Chicago, Illinois.
Known for
She is known for her theory about evolution through cells. She stated that multicellular things evolved from single celled items. She was also known for her contributions to the Endosymbiotic theory and her theory on the origin of eukaryotic cells. One of her more recent theories is the Gaia theory.

Science Explained
The Endosymbiotic theory states that the key organelles (the cells that are usually coated in a thin layer of lipid bilayer) of eukaryotes (an organism that has cells that contain a nucleus and membrane) originated as a symbiosis relationship. Symbioses is a close relationship between too things. Her theory about the origin of eukaryotic cells is quite similar to her contributions to a lot of her other work. Eukaryotic cells are organisms that cells contain a nucleus and a membrane. The Gaia theory is the theory that world as a whole is alive.

She was a biologist and a professor who taught botany. Throughout her career Dr. Margulis was always questioning things that had already been established as facts. Her persistent questioning changed many things that were already thought to be true. In the 1960s she began her studies of cells.

Did you know?
Lynn Margulis was the oldest child of four girls; she married twice and divorced twice. One of her more recent theories before she died was the Gaia theory. Much of her work was done with scientist James Lovelock who is currently living in England.
