Phrase: serial endosymbiosis theory | Statement: [Microcosmos, associatedWithTheory, serial endosymbiosis theory]

Target entity: serial endosymbiosis theory
Context triple: [Microcosmos, associatedWithTheory, serial endosymbiosis theory]

• A. Symbiosis in Cell Evolution
  Symbiosis in Cell Evolution is a landmark scientific book by Lynn Margulis that argues complex eukaryotic cells arose through symbiotic mergers of simpler organisms, helping establish the endosymbiotic theory in evolutionary biology.
• B. Origin of Eukaryotic Cells
  Origin of Eukaryotic Cells is a landmark scientific book by Lynn Margulis that advanced the endosymbiotic theory explaining how complex eukaryotic cells evolved from symbiotic relationships between simpler prokaryotic organisms.
• C. “From Metabolism to Symbiosis”
  “From Metabolism to Symbiosis” is a theoretical work by Japanese architect Kisho Kurokawa that traces his evolution from the Metabolist movement toward a philosophy of architecture based on coexistence and symbiotic relationships.
• D. Haldane–Oparin hypothesis of the origin of life
  The Haldane–Oparin hypothesis of the origin of life proposes that life first arose through a gradual chemical evolution of organic molecules in Earth’s early “primordial soup,” eventually leading to self-replicating systems.
• E. Microcosmos: Four Billion Years of Microbial Evolution
  Microcosmos: Four Billion Years of Microbial Evolution is a popular science book by Lynn Margulis that explores the central role of microbes in the evolution and functioning of life on Earth.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions

Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: serial endosymbiosis theory
Triple: [Microcosmos, associatedWithTheory, serial endosymbiosis theory]

Serial endosymbiosis theory is a scientific hypothesis proposing that key organelles of eukaryotic cells, such as mitochondria and chloroplasts, originated through successive symbiotic mergers between ancestral prokaryotic organisms.
