Among her most important work was the development of the serial endosymbiotic theory (SET) of the origin of cells, which posits that eukaryotic cells (cells with nuclei) evolved from the symbiotic merger of nonnucleated bacteria that had previously existed independently.

What evidence did Lynn Margulis provide to support the endosymbiotic theory?
By the time Margulis proposed her theory, evidence for symbiosis theories was available from microscope studies of cells, electron microscopy, genetics, and molecular biology. Such evidence enabled Margulis to support her theories with experimental data.

What was Lynn Margulis theory?
Lynn Margulis was an eminent American evolutionary biologist. Her serial endosymbiotic theory (SET) of eukaryotic cell development overturned the modern concept of how life originated on earth. She argued that different types of bacteria, through “symbiogenesis”, formed more complicated single organisms.
What is the Margulis endosymbiotic hypothesis?
In her article, Margulis hypothesized that “three fundamental organelles: the mitochondria, the photosynthetic plastids and the (9 + 2) basal bodies of flagella were once themselves free-living (prokaryotic) cells.” That mitochondria and plastids might have originated endosymbiotically from prokaryotic progenitors was ...
What is the theory of endosymbiotic theory?
The endosymbiotic theory states that some of the organelles in today's eukaryotic cells were once prokaryotic microbes. ... They eventually lost their cell wall and much of their DNA because they were not of benefit within the host cell. Mitochondria and chloroplasts cannot grow outside their host cell.
