|
Species |
a group of organisms that is capable of breeding with each other in nature to produce fertile offspring |
basic grouping used in biological classification |
|
|
Homologies |
structural resemblances |
Important in classification because classification relies on linking species to ancestors
|
|
|
Analogies |
structures that are similar in appearance and function but are not the result of shared ancestors.
|
EX: wings of birds and insects |
|
|
Binomial nomenclature |
a two word naming system
|
EX: Linnean system
|
|
|
Eubacteria |
A group within Monera
|
The other one in Archaea
|
|
|
Archaea |
A group within the Monera Kingdom
|
The other one is Eubacteria
|
|
|
Protista |
A kingdom that consists of mostly microscopic unicellular
|
mostly aquatic |
|
|
Fungi |
a kingdom of heterotrophic organisms that develop spores |
many are decomposers
|
|
|
Plantae |
the kingdom that consists of plants
|
EX: trees and flowers
|
|
|
Animalia |
the kingdom that consists of animals
|
EX:Whales, Humans, Rat
|
|
|
Clade |
a group of organisms that share a common ancestor |
like cladistics |
|
|
Coevolution |
evolution of two species interacting with eachother |
influence each others adaptations |
|
|
Adaptation |
a characteristic that improves an organism's chance of survival |
can start with a mutation |
|
|
Speciation |
the origin of new species as a result of evolution
|
creation of new species |
|
|
Geographic isolation |
when a population of a species is separated from another population by geography
|
can't exchange genetic material
|
|
|
Adaptive radiation |
rapid increase in speciation |
adaptations of Darwin's finches
|
|
|
Common Ancestor |
an animal that a group of animals is all a descendant of
|
these animals form a clade
|
|
|
Stasis |
the rate of large-scale change remaining slow for a long period of time |
may occur because of well adapting and a stable environment
|
|
|
Gradualism |
new species branchine off from ancestral species and continuing to change at a similar rate |
a pattern of evolution
|
|
|
Punctuated equilibrium |
a short period of rapid change just after a population becomes isolated and forms a new species |
is a pattern of evolution |
