|
Species |
All individuals and populations of a particular type of organism that can interbreed with one another |
|
|
Homologies |
Similarities of biological structures that results from evolution from a common ancestor |
|
|
Analogies |
Similarities in form or function that is not a result of evolution from a common ancestor but is evidence of convergent evolution |
|
|
Binomial nomenclature |
The two-word naming system used in taxonomy, consisting of Latin genus and the species name of an organism |
|
|
Eubacteria |
a bacterial group including cyanobacteria; they differ from archaebacteria in their ribosomal RNA and transfer RNA in different ways |
|
|
Archae |
domain of bacterial species on the basis of RNA analysis |
|
|
Protista |
a kingdom of mostly aquatic, unicellular eukaryotes |
|
|
Fungi |
a kingdom of heterotrophic organisms that develop spores; feed by absorbing rather than ingesting; many are decomposers |
|
|
Plantae |
the plant Kingdom |
|
|
Animalia |
the animal kingdom |
|
|
Cladistics |
groups its species according to ancestry and homologous characteristics not found in other organisms |
|
|
Coevolution |
the evolution of two species interacting with each other and reciprocally influencing each other's adaptations |
|
|
Adaptiation |
A characteristic that improves and organism's chance of surviving |
|
|
Adaptive Radiation |
the development of numerous species from a common ancestor in a diverse environment |
|
|
Common Ancestor |
an ancestral form or species from which two different species evolved |
|
|
Geographic isolation |
The separation of two populations of the same species or breeding group by a physical barrier
|
|
|
Gradualism |
a model of evolution in which change takes place at a slow, steady rate resulting in a steady increase in biological diversity |
|
|
Punctuated equillibrium |
a model of evolution in which separation occurs in spurts of relatively rapid change followed by long periods of stability |
|
|
Speciation |
the appearance of a new species |
|
|
Stasis |
a state of inactivity or balance |
