Answer:

Lynn Margulis developed the endosymbiotic theory, to explain the origin of eukaryotes.

Explanation:

The endosymbiotic theory, also known as Symbiogenesis, is a theory of evolution which explains the origin of the eukaryotic cells from prokaryotes. This theory states that the organelles that distinguish the eukaryote cells were evolved from the individual single-celled prokaryotes through symbiosis.

Also, cell organelles present in the eukaryotic cells like plastids (chloroplast), mitochondria and other organelles represent the previously free-living prokaryotes, that have been taken one inside the other in endosymbiosis.
