What Is Symbiogenesis Theory?

Symbiogenesis, endosymbiotic theory, or serial endosymbiotic theory, is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms.

What does the Endosymbiotic theory say?

The Endosymbiotic Theory states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote). This theory explains the origin of eukaryotic cells.

Is symbiogenesis the same as Endosymbiotic theory?

Symbiogenesis refers to the crucial role of symbiosis in major evolutionary innovations. The term usually refers to the role of endosymbiosis for the origin of eukaryotes. Symbiogenesis may also be applicable to other evolutionary innovations. The role of symbiosis can be integrated with existing evolutionary theory.
