Speciation and Taxonomy Flashcards
what is the binomial system?
a system in which each organism is given two-part names
based on latin or greek
What make up the two part name in the binomial system?
- generic name
- specific name
What in the generic name of a species?
the genus of the organism
What in the specific name of a species?
the species of organism
How do you write it down?
- capitalise the generic name
- underline the full binomial name
what makes up the classification system?
in order
- Domain
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species
What is a species?
a group of organisms that are similar and can reproduce and create fertile offspring
What are the types of classification?
- hierachal
- phylogenetic
What is hierachal classification?
when organisms are organised by putting smaller groups in larger ones
What is phylogenetic classification?
when organisms are organised by their evolutionary origins and relationships
what are taxons?
taxa if plural
the groups in hierachal classification
How do species recognise each other?
courtship behaviour
What are the purposes of courtship behaviours?
- recognise members of their species
- synchronise mating
- form a pair bond
- become able to breed
What are courtship behaviours?
the behaviours in which members of a species select reproductive partners
How is courtship behaviour important for survival of species?
it ensures that they can reproduce and create fertile offspring (prevents them from going extinct)
