[11] [12] The Russian botanist Boris Kozo-Polyansky became the first to explain the theory in terms of Darwinian evolution. [13] In his 1924 book A New Principle of Biology. Essay on the Theory of Symbiogenesis, [14] he wrote, "The theory of symbiogenesis is a theory of selection relying on the phenomenon of symbiosis." [15]
An overview of the endosymbiosis theory of eukaryote origin (symbiogenesis). Symbiogenesis theory holds that eukaryotes evolved via absorbing prokaryotes. Typically, one organism envelopes a bacterium and the two evolve a mutualistic relationship. The absorbed bacteria (the endosymbiont) eventually lives exclusively within the host cells.
The symbiosis, subsequently also discovered in varying degrees in other protists such as Strigomonas culicis, Novymonas esmeraldas, Diplonema japonicum and Diplonema aggregatum are considered as good models for the understanding of the evolution of eukaryotes from prokaryotes, [3] [4] [5] and on the origin of cell organelles (i.e. symbiogenesis).
Endogenosymbiosis is an evolutionary process, proposed by the evolutionary and environmental biologist Roberto Cazzolla Gatti, in which "gene carriers" (viruses, retroviruses and bacteriophages) and symbiotic prokaryotic cells (bacteria or archaea) could share parts or all of their genomes in an endogenous symbiotic relationship with their hosts.
The process is widely agreed to have involved symbiogenesis, in which an archeon and a bacterium came together to create the first eukaryotic common ancestor (FECA). This cell had a new level of complexity and capability, with a nucleus, at least one centriole and cilium , facultatively aerobic mitochondria , sex ( meiosis and syngamy ), a ...

Ford said it would cut around 14% of its European workforce on Wednesday, blaming losses in recent years due to weak electric vehicle demand, poor government support for the EV shift and ...
The hydrogen hypothesis is a model proposed by William F. Martin and Miklós Müller in 1998 that describes a possible way in which the mitochondrion arose as an endosymbiont within a prokaryotic host in the archaea, giving rise to a symbiotic association of two cells from which the first eukaryotic cell could have arisen (symbiogenesis).
