Modern evolutionary synthesis
The modern evolutionary synthesis is a 20th-century synthesis of ideas from several fields of biology which provides a widely accepted account of evolution. It is also referred to as the new synthesis...
Salamander Has Algae Living Inside Its Cells
In a symbiotic union more complete than any previously found in vertebrates, the common spotted salamander lives with algae inside its cells. Such a degree of cross-species fusion was long thought to ...
The eclipse of Darwinism
The eclipse of Darwinism was a phrase used by Julian Huxley to describe the state of affairs prior to the modern evolutionary synthesis when evolution was widely accepted in scientific circles but rel...

Endosymbiont
An endosymbiont is any organism that lives within the body or cells of another organism, i.e. forming an endosymbiosis (Greek: ἔνδον endon "within", σύν syn "together" and βίωσις biosis "living"). Ex...

Endosymbiotic theory
Symbiogenesis, or endosymbiotic theory, is an evolutionary theory which explains the origin of eukaryotic cells from prokaryotes. It states that several key organelles of eukaryotes originated as symb...

Evolutionary developmental biology
Evolutionary developmental biology (evolution of development or informally, evo-devo) is a field of biology that compares the developmental processes of different organisms to determine the ancestral ...
Human microbiome
The human microbiota is the aggregate of microorganisms, a microbiome that resides on the surface and in deep layers of skin (including in mammary glands), in the saliva and oral mucosa, in the conjun...
Hydrogen hypothesis
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 prokaryote (an arc...
Gut bacteria
Gut flora or, more appropriately, gut microbiota, consists of a complex community of microorganism species that live in the digestive tracts of animals and is the largest reservoir of microorganisms ...
Rhizobia
Rhizobia are soil bacteria that fix nitrogen (diazotrophs) after becoming established inside root nodules of legumes (Fabaceae). Rhizobia require a plant host; they cannot independently fix nitrogen. ...

Chloroplast
Chloroplasts /ˈklɔrəplæsts/ are organelles, specialized subunits, in plant and algal cells. Their main role is to conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the ener...

Mixotricha paradoxa
Mixotricha paradoxa is a species of protozoan that lives inside the gut of the Australian termite species Mastotermes darwiniensis and has multiple bacterial symbionts. The name, given by the Australi...

Orthogenesis
Orthogenesis, orthogenetic evolution, progressive evolution or autogenesis, is the hypothesis that life has an innate tendency to evolve in a unilinear fashion due to some internal or external "drivin...

Viral eukaryogenesis
Viral eukaryogenesis is the hypothesis that the cell nucleus of eukaryotic life forms evolved from a large DNA virus in a form of endosymbiosis within a methanogenic Archaea. The virus later evolved i...
Mitochondrion
The mitochondrion (plural mitochondria) is a membrane-bound organelle found in most eukaryotic cells. The word mitochondrion comes from the Greek μίτος, mitos, i.e. "thread", and χονδρίον, chondrion, ...
Population genetics
Population genetics is the study of the distributions and changes of allele frequency in a population, as the population is subject to the four main evolutionary processes: natural selection, genetic ...
Theistic evolution
Theistic evolution, theistic evolutionism or evolutionary creationism are views that regard religious teachings about God as compatible with modern scientific understanding about biological evolution....
Mutation theory
Mutationism refers to historical and contemporary views of evolution that emphasize the role of mutation and that are understood as alternatives to Darwinism. In the mutationist view, change may occur...
Saltationism
In biology, saltation (from Latin, saltus, "leap") is a sudden change from one generation to the next, that is large, or very large, in comparison with the usual variation of an organism. The term is ...
Lamarkism
Lamarckism (or Lamarckian inheritance) is the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring (also known as heritability of acquired characteri...

Computational phylogenetics
Computational phylogenetics is the application of computational algorithms, methods, and programs to phylogenetic analyses. The goal is to assemble a phylogenetic tree representing a hypothesis about ...
Endogenous retrovirus
Endogenous retroviruses (ERVs) are endogenous viral elements in the genome that closely resemble and can be derived from retroviruses. They are abundant in the genomes of jawed vertebrates and they oc...
Baldwin effect
In evolutionary biology, the Baldwin effect, also known as Baldwinian evolution or ontogenic evolution, describes the effect of learned behavior on evolution. In brief, James Mark Baldwin suggested th...
