What does the phylogenetic species concept examine?
It examines the phylogeny ( the evolutionary history of a species) or evolutionary history of organisms.
What does the biological species concept define?
Species on the basis of whether two organisms can produce fertile offspring.
What is the system of standard names for species?
Binomial Nomenclature
Definition of species?
A group of organisms that can interbreed in nature and produce fertile offspring.
What does species concept do?
It is how scientists define various definitions of species.
Meaning of Morphology
The branch of biology that deals with the structure or form of organisms
Meaning of Phylogeny
The evolutionary history of species
What does the morphological species concept focus on?
Focuses on morphology - the body, size, and other structural features.
Definition of Taxonomy
The branch of biology that identifies names and classifies species based on natural features.
Who is Carl Von Linne / Carolus Linnaeus?
A Swedish scientist who is considered to be the Father of Taxonomy and Binomial Nomenclature.
Binomial nomenclature definition
Binomial : two parts
Nomenclature: naming system
First word is the genus ( plural genera, taxonomic group of a closely related species), the second word identifies the particular species.
How is the Binomial Nomenclature written?
It is italicized when typed, with the genus name capitalized and the species in lower case.
When written by hand both are underlined.
Classification definition
The grouping of organisms based on the set of criteria that helps to organize and indicate evolutionary relationships.
Hierarchical Classification definition
The method of classifying organisms in which species are arranged in categories from most general to most specific.
What is the Taxonomic categories used for?
Used to classify by assigning organisms that have been named and identified.
