Where Did Eukaryotic Cells Come From - A Journey Into Endosymbiotic Theory

The video explores the evolution of life on Earth, focusing on the transition from simple prokaryotic cells to complex eukaryotic cells with membrane-bound organelles. It introduces the endosymbiotic theory, explaining how certain organelles like mitochondria and chloroplasts originated from symbiotic relationships between cells. The video also examines various examples of endosymbiosis in single-celled organisms like Paramecium bursaria and amoebas, as well as in multicellular organisms like hydra. It highlights the mutual benefits of these relationships and questions the boundaries of what constitutes an individual organism.
