Classification Flashcards
Classification
Process of sorting living organisms into groups for evolutionary relationships to be understood
Taxonomy
Theory and practise of classification
Species
Members of the same species are capable of breeding to produce fertile offspring
And with similar features
Points of courtship
- attracts same species
- attracts members of opposite sex
- indicates sexual maturity
- stimulates release of gametes
- form pair bond
Phlogeny
Evolutionary relationship between orgamisms
Hierarchy
Groups within groups without overlap - groups are called taxa
Hierarchy order largest to smallest
Domain
Kingdom
Phylem
Class
Order
Family
Genus
Species
Why is bionomial nomenclature in latin
Can be understood worldwide
How to write the bionomial properly
Genus and species underlined with the genus having a capital letter at the start
Phlogenetic trees
Shows the phlogenetic relationship between species
Space between branches of phyligenetic tree
Closer the branches, closer the evolutionary relationships between organisms
Reasons its difficult to know if organisms belong to the same species
Some organisms appear different but are the same species
Some organisms reproduce asexually
Extinct species cannot be bred
Modern classification is based on
- DNA base sequencing
- mRNA base sequencing
- Amino acid seqencing
