All organisms arose from a single common ancestor.
An endosymbiont or endobiont is any organism that lives inside the frame or cells of some other organism most often, though no longer continually, in a mutualistic relationship.
Bacterial endosymbionts result in dramatic phenotypes in their arthropod hosts, including cytoplasmic incompatibility, feminization, parthenogenesis, male killing, parasitoid protection, and pathogen blocking.
Endosymbionts, such as Wolbachia, Rickettsia, and Cardinium, are a type of bacteria generally located in arthropod species inclusive of bugs, spiders, crustaceans, and mites, in addition to other invertebrates along with filarial nematodesEndosymbiosis is a form of symbiosis in which the symbiont lives in the body of its host and the symbiont in an endosymbiosis is known as an endosymbiont.
