4.5 species & taxonomy

• what is courtship behaviour?

  behaviours of closely related species are more similar, the ability to display behaviours is genetically determined and increases chances of survival
• what is artificial classification?

  Grouping organisms based on easily observable characteristics such as colour or size
• what is phylogenetic classification?

  Grouping organisms based on their evolutionary relationships with no overlap between groups
• what is the order of taxonomy?

  domain, kingdom, phylum, class, order, family, genus, species
• what system is used to name species?

  binomial system- 1st part of the species names= is the genus (written in caps) 2nd part of the name is the species (lower case)
• hierarchy of phylogenetic classification is where smaller groups are placed within larger groups with no overlap
• two organisms belong to the same species if they are able to produce fertile offspring
• advances in immunology and genome sequencing help to clarify evolutionary relationships between organisms.
