SUMMARY
The evolution of eukaryotic cells is primarily explained by the endosymbiotic theory, which posits that organelles within eukaryotic cells originated from prokaryotic cells that formed symbiotic relationships. This theory is supported by substantial scientific evidence, including genetic and biochemical data, which demonstrate the similarities between mitochondria, chloroplasts, and their prokaryotic ancestors. Critics of the theory exist, but the foundational research remains robust and widely accepted in the scientific community.
PREREQUISITES
