|
Species |
A conceptual group of all individuals of a type of organism that can interbreed. |
Humans are a species; humans can interbreed only with other humans. |
|
|
Homology |
A structural similarity that suggests common ancestry. |
Limbs of birds, reptiles, fish, mammals, and amphibians. |
|
|
Analogy |
Structural similarity that does not evidence common ancestry, instead suggesting convergent evolution. |
Insects' and birds' wings. |
|
|
Binomial nomenclature |
The two-word way of naming organisms. |
Homo sapiens, the name, has two parts. |
|
|
Eubacteria |
The bacterial group that includes cyanobacteria and has different rRNA and RNA transfer than Archaebacteria. |
Cyanobacteria are members of Eubacteria. |
|
|
Archaea |
Bacterial species group based off of RNA analysis. |
Proposed by Carl Woese, it isn't Eubacteria. |
|
|
Protista |
Organisms that aren't in another group. |
Kelp is an example of this kingdom that can be unicellular or multicellular. |
|
|
Fungi |
Organisms that absorb, develop spores, are heterotrophs, are often decomposers, and have chitinous cell walls. |
Mushrooms. |
|
|
Plantae |
Autotrophic organisms that store food as starch, perform photosynthesis, have cell walls have cellulose. |
A tree. |
|
|
Animalia |
The kingdom of motile heterotrophs - animals. |
Humans, birds, fish, etc. |
|
|
Clade |
The group of organisms that evolves from one common ancestor. |
Primates are in the same clade. |
|
|
Coevolution |
"The continuous adaptation of different organisms to each other." |
Tortoise neck length and height of cacti. |
|
|
Adaptation |
Any characteristic that helps an organism to live better. |
Penguins are adapted to many different locales around the Southern Hemisphere. |
|
|
Speciation |
The appearances of a new species. |
Atriplex robusta. |
|
|
Geographic isolation |
Separation between populations in different places. Geographic + Isolation. |
The Kaibab and the Abert's species of squirrels. |
|
|
Adaptive radiation |
A rapid increase in speciation. |
Populations diversifying to avoid competition. |
|
|
Common ancestor |
A species from which multiple species are both/all derived from. |
A species from which two species evolved. |
|
|
Stasis |
A state of little evolutionary change in a species. |
The Australian lungfish. |
|
|
Gradualism |
Speciation through gradual accumulation of changes. |
Species slowly becoming different. |
|
|
Punctuated equilibrium |
Rapid change in a species just after an isolation. |
Immediate change after a relocation. |
