4.5 Species & Taxonomy Flashcards
(17 cards)
Define species
A group of organisms that can interbreed to produce fertile offspring.
What is one advantage of courtship behaviour?
Individuals can recognise sexually mature members of their own species of the opposite sex.
How does courtship behaviour help in mating?
It allows individuals to synchronise mating.
What is a benefit of courtship behaviour in terms of relationships?
It helps form a pair bond.
What is an outcome of successful courtship behaviour?
It leads to successful breeding.
Define classification
The process of arranging organisms into groups.
Classification hierarchy (name the 8 groups, largest to smallest)
Domain → kingdom → phylum → class → order → family → genus → species.
Universal naming system
Binomial naming system.
What does the generic name in a binomial name represent?
The genus the organism belongs to.
What do two closely related species share in terms of binomial nomenclature?
They share the same genus.
What does the specific name in a binomial name represent?
The species the organism belongs to.
How should the first letter of the generic name in a handwritten binomial name be formatted?
The first letter should be capitalised.
How should the rest of the generic name in a handwritten binomial name be formatted?
The rest should be in lowercase.
How should a handwritten binomial name be visually represented?
The whole name should be underlined.
What is phylogenetic classification?
The process of arranging organisms into groups based on their evolutionary origins and relationships.
How can we clarify evolutionary relationships between organisms?
Analyse their molecular differences. Advances in immunology/genome sequencing provide clear pictures of how related two organisms are.
Hierarchical classification
Groups within groups; no overlap between groups.
