|
Species
|
Basic grouping used in biological classification |
|
|
|
Homologies |
Condition of being homologous
|
Structural resemblances |
|
|
Analogies |
Similarity in form or function that is not a result of evolution from a common ancestor |
|
|
|
Binomial Nomenclature
|
A two word naming system to identify each species |
Used by the Linnean system
|
|
|
Eubacteria |
Bacterial group including the Cyanobacteria |
Monera is divided into two main groups called Eubacteria and Archae
|
|
|
Archae |
Domain of bacteria species on the basis of RNA analysis |
Section of monera group
|
|
|
Protista
|
A kingdom of mostly aquatic, unicellular eukaryotes |
Protista consists of mostly microscopic unicellular eukaryotes |
|
|
Fungi |
Kingdom of heterotrophic organisms |
Mushrooms, other decomposers |
|
|
Plantae |
Plant kingdom |
Multicellular, photoautotrophic eukaryotes |
|
|
Animalia |
Animal kingdom |
Heterotrophic multicellular eukaryotes |
|
|
Clade
|
Life-form group consisting of an ancestor and all its descendants |
Family tree |
|
|
Coevolution |
Change of an organism triggered by the change of a related organism |
Ex: squirrels and dogs
|
|
|
Adaptation
|
Trait that is maintained and evolved by means of natural selection |
Adaptations enhance the fitness and survival of individuals |
|
|
Speciation |
Evolutionary process by which new biological species arise |
Speciation is the splitting of species |
|
|
Geographic isolation
|
Group of plants, animals, or other living creatures being separated from mixing genes within their same species |
Geographic isolation is the people of a remote village are only able to reproduce within the village population |
|
|
Adaptive radiation |
The development of numerous species from a common ancestor in a diverse environment |
Patten in evolution |
|
|
Common ancestor |
Characteristics of how things evolved |
|
|
|
Stasis |
A state of balance among opposing forces |
Ex: fossil records May occur because a population or species is well adapted and it's environment remains stable |
|
|
Gradualism
|
A model of evolution in which change takes place at a slow and steady rate |
|
|
|
Punctuated equilibrium |
A model of evolution in which speciation occurs in spurts of relatively rapid change |
Model of evolution |
