1966: The Evolutionary Theory of Endosymbiosis – Tracing the Origins of Cellular Complexity

Endosymbiosis, first proposed by Konstantin Mereschkowski and later advanced by Lynn Margulis, is a fundamental evolutionary theory explaining the origin of complex eukaryotic cells from symbiotic relationships with prokaryotic organisms

This image shows the fossilized remains of microfossils known as Eosphaera, located within the over 3.4-billion-year-old Gunflint chert formation in Pilbara, Western Australia. These microorganisms are thought to possibly represent transitional forms between prokaryotes and eukaryotes.
