Koalas play crotchet on fluffy ground sometimes Kingdom Phylum Class Order Family Genus Species
What is a domain?
A further level of classification in the hierarchy. This level of classification is placed at the top of the hierarchy.
Why do scientists classify organisms?
- to identify species
- to predict characteristics
- to find evolutionary links
What are the advantages of using the binomial naming system?
Scientists worldwide can share their research
Links between different organisms can be seen, even if they live on different continents
What are the three domains?
Archaea
Bacteria
Eukarya
Define species
A group of organisms that can interbreed to produce fertile offspring
Why are the offspring of different species infertile?
They have an odd number of chromosomes. This means that meiosis and gamete production cannot take place correctly as all chromosomes must all pair up.
Describe the binomial naming system
The first word indicates the organisms genus. It called the generic name.
The second word indicates the organisms species. It is called the specific name.
