How does the Linnaean system of classification give an indication of degree of relatedness of different species?
Closely related species have the same generic name
Why use the scientific name?
- Are universal
- Gives indication of degree of relatedness of different species
True or False?
Organisms that share the same species name but different generic names are related
False -
Organisms that have the same species name but different generic names are not necessarily related
Why do we classify?
(name at least 1, then increase every time card appears)
- Identify species
- Organise species
- Understand species
- Protect + Conserve
- Communicate importance
What is the first classification step?
Identify similarities + differences
What is the second classification step?
Identify potential categories
What is the third classification step?
Choose the appropriate group
