1. Symbiogenesis

   Symbiogenesis (endosymbiotic theory, or serial endosymbiotic theory,) is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms. The theory holds that mitochondria, plastids such as chloroplasts, and possibly other organelles of eukaryotic cells are descended from formerly free-living prokaryotes (more closely related to the Bacteria than to the Archaea) taken one inside the other in endosymbiosis. Mitochondria appear to be phylogenetically related to Rickettsiales bacteria, while chloroplasts are thought to be related to cyanobacteria. The idea that chloroplasts were originally independent organisms that merged into a symbiotic relationship with other one-celled organisms dates back to the 19th century, when it was espoused by researchers such as Andreas Schimper. The endosymbiotic theory was articulated in 1905 and 1910 by the Russian botanist Konstantin Mereschkowski, and advanced and substantiated with microbiological evidence by Lynn Margulis in 1967. Among the many lines of evidence supporting symbiogenesis are that new mitochondria and plastids are formed only by splitting in two, and that cells cannot create new ones otherwise; that the transport proteins called porins are found in the outer membranes of mitochondria, chloroplasts, and bacterial cell membranes; that cardiolipin is found only in the inner mitochondrial membrane and bacterial cell membranes; and that some mitochondria and plastids contain single circular DNA molecules similar to the circular chromosomes of bacteria.

1. Symbiogenesis

   Symbiogenesis is the merging of two separate organisms to form a single new organism. The idea originated with Konstantin Mereschkowsky in his 1926 book Symbiogenesis and the Origin of Species, which proposed that chloroplasts originate from cyanobacteria captured by a protozoan. Ivan Wallin also supported this concept in his book "Symbionticism and the Origins of Species". He suggested that bacteria might be the cause of the origin of species, and that species creation may occur through endosymbiosis. Today both chloroplasts and mitochondria are believed, by those who ascribe to the endosymbiotic theory, to have such an origin. In Acquiring Genomes: A Theory of the Origins of Species, biologist Lynn Margulis argued later that symbiogenesis is a primary force in evolution. According to her theory, acquisition and accumulation of random mutations are not sufficient to explain how inherited variations occur; rather, new organelles, bodies, organs, and species arise from symbiogenesis. Whereas the classical interpretation of evolution emphasizes competition as the main force behind evolution, Margulis emphasizes cooperation. She argues that bacteria along with other microorganisms helped create the conditions that we require for life, such as oxygen. Margulis believes that these microorganisms make up a major component in Earth’s biomass and that they are the reason current conditions on earth are maintained. She also believes that the DNA in the cytoplasm of animal, plant, fungal and protist cells, rather than resulting from mutations, resulted from genes from bacteria that became organelles. She claimed that bacteria are able to exchange genes more quickly and more easily, and because of this, they are more versatile, which is why life was able to evolve so quickly.
